Metabolic & Specialty Labwork

Functional Medicine Testing

Introduction

Our clinic is setup to offer novel and cutting edge laboratory assessments not available at traditional medical practices. Through use of these specialty lab panels we are able to uncover issues that are routinely overlooked elsewhere, providing relief to patients.

Gastro Intestinal

Digestive and Intestinal Health Markers

Although overlooked by many doctors, the gastrointestinal system, is an area that can deliver crucial information about whether your body is functioning properly. Specialty testing provides detailed information about whether your gut operates effectively to deliver the nutrients you need to thrive.  The cellular function of every organ in your body is dependent on nourishing substances obtained through digestion.

Specialty testing can help reveal clinical information about your health:

Excess bacterial enzyme activity in the intestine that can promote hormonal imbalances and gastrointestinal irritation.

Chronic digestive dysfunction that can set the stage for the development of leaky gut, food allergies, toxic stress and systemic autoimmune reactions.

Short chain fatty acid inadequacy linked to increased incidence of colon cancer and ulcerative colitis.

Chronic dysbiosis (altered bacterial balance) and inflamation that can impair absorption, leading to deficiencies of nutrients, proteins, carbohydrates and fats.

Bacterial and yeast overgrowth underlying gastrointestinal symptoms, chronic fatigue, mood shifts and weakened immune function.

Increased toxic burden, small bowel bacteria overgrowth and severe inflammation.

The presence of parasites.

Maldigestion and the cause of symptoms such as gas and bloating, abdominal pain, diarrhea and constipation.

Lactose intolerance and its relationship to gas, bloating, cramping, and diarrhea.

Intestinal Permeability or Leaky Gut can contribute to joint pain, head-aches, and others. More Information.

Through testing, it is possible to determine whether food breaks down into usable substances, whether you absorb certain nutrients, and whether you properly eliminate waste. A healthy body also has beneficial bacteria to counteract the impact of “bad” bacteria, and produces and secretes enzymes, hormones and digestive chemicals.

GI or Gut Testing Provides a Window to your Immune Function

Food allergies, toxins, sugar, antibiotics, parasites and stress can wreak havoc with your gastrointestinal system, upsetting the balance in your intestine as well as allowing harmful substances to enter the system. Gas, bloating, diarrhea, constipation or abdominal discomfort may be the first clue that something is wrong with the digestive tract, but did you know allergies or simple lack of energy and fatigue can often be traced to digestive problems as well?

Chronic vaginal infections may result from similar flora imbalances as in the intestine. Laboratory examination of vaginal secretions can help you to identify the exact cause of chronic itching, discomfort, or discharge, and establish a treatment program to get you back on track.

Probiotics and Antibiotics

The intestinal tract contains large amounts of beneficial bacteria that produce some B vitamins and provide stimulus for proper immune function. However, if your stomach acid is not adequate, if you fail to digest protein, or if your diet does not supply sufficient fiber, the resulting overgrowth of unfavorable bacteria can release toxic products that your body must remove. These toxic products include: benzoate, hippurate, phenylacetate, phenylpropionate, p-hydroxybenzoate, p-hydroxyphenylacetate, indican, and tricarballylate. Your potential to benefit from consuming extra sources of favorable organisms (called probiotics) may go up as the number of toxic compounds and their concentrations increase.

Lactobacillus Acidophilus

D-Lactate elevation is an exception to the use of probiotics just described. Lactobacillus acidophilus is widely considered a favorable bacterium to colonize the human gut. It has beneficial effects in many individuals. However, if you have any tendency for carbohydrate malabsorption, even favorable organisms (i.e., L. acidophilus) can grow so fast that your blood becomes highly acidic due to the formation of D-lactate. This condition is revealed by high D-lactate in urine.

Saccharomyces Boulardii

It is difficult to know the exact identification of organisms that may be producing the compounds found in your urine. However, one specific compound, dihydroxyphenylpropionate seems to be strongly associated with a particularly troublesome type of bacteria called Clostridia. This organism is frequently the cause of travelers diarrhea, but its by-products may produce other symptoms. Species of Clostridia are particularly susceptible to displacement by the favorable organism called Saccharomyces boulardii that is available in capsules.

Antifungals

Yeast is another class of microbes that can chronically grow in the intestinal tract and cause health effects through the release of toxic metabolites. Because of the multiple, non-specific symptoms they can produce, doctors have searched for ways to know when yeast overgrowth is a problem. D-Arabinitol is uniquely produced by intestinal yeast, and the degree of elevation is a useful marker of its growth.

Pre-Diabetes Risk Factors

Inflammatory Markers:

Inflammation is the underlying driver of progression to diabetes, particularly in the development of insulin resistance. These include Tumor Necrosis Factor-alpha (TNF-alpha); Interleukins-6 & -8 (IL-6 & IL-8); highly sensitive C-Reactive Protein (hsCRP); and Plasminogen Activator Inhibitor Type I (PAI-1).

Metabolic Markers:

These markers measure the function of your pancreas and liver in producing and processing insulin. Markers evaluated include: Fasting Glucose which measures sugar in the blood stream. Adiponectin – derived from fast cells, lowers blood pressure, protects against cardiovascular disease, obesity, and insulin resistance. Fasting Insulin – comes from the pancreas, can help determine the etiology of high blood sugar, and used to diagnose insulin resistance. ProInsulin – precursor of insulin, high levels indicate increased risk or presence of diabetes. HOMA-IR (homestastic model assessment insulin resistance) calculation of fasting glucose and insulin, considered a gold standard for quantifying insulin sensitivity. Leptin – hormone from fast cells that regulates appetite, metabolic rate, and body weight, considered protective against obesity. HbA1C – indication of blood sugar control in the last 3 months, small elevations can predict future diabetes among individuals with impaired glucose tolerance.

Cardio-Vascular

Metabolic markers include LDL-Particle Number (LDL-P) which is independent of the regularly reported LDL cholesterol concentration (LDL-C). A person with normal LDL-C concentration and high LDL-P, is still at high-risk for plaque build-up. HDL-Particle Number (HDL-P) indicates increased risk of coronary events for individuals with a low HDL-P number, even in individuals with optimal levels of LDL-P. LDL-Size is highly associated with triglycerides and insulin resistance. Lipoprotein(a) or Lp(a) is influenced by heredity and has a strong association with coronary and peripheral cardiac events. hs C-reactive protein (hs-CRP) is an independent marker for systemic inflammation. High levels are linked to coagulation and vascular endothelium damage. Lipoprotein-associated phospholipase (Lp-PLA2), aka PLAC, is produced in the intima, promoting inflammation and plaque instability. It is specific for vascular inflammation. Homocysteine is an amino acid that has been linked to damaged endothelium, increased platelet aggregation, and the formation of atherosclerotic lesions. Fibrinogen plays a key role in arterial occlusion by promoting thrombus formation, endothelial injury and hyper-viscosity. Insulin Resistance score determined by lipid sub-fractionation.

Genetic and Genomic Testing

Consider genetic testing in the following circumstances:

  • You have a family history of disease.
  • You would like to develop a focused plan to prevent inherited risks from manifesting into actual disease.
  • You would like to know if you have genetic variations that make you more vulnerable to the harmful effects of toxins.
  • You would like to know if you have genetic variations that affect your biological response to certain drugs or nutrients.
  • You have a medical condition that resists medical treatment

Through a simple blood test, Dr. Hirani can evaluate your individual genetic predispositions, and then implement a targeted, customized intervention plan before any disease develops. Many people mistakenly assume that the presence of a genetic flaw means they are destined to experience disease. NOT TRUE! Most genes have flexible expressions and are often influenced by modifiable environmental, diet and lifestyle factors. Poor diet; chronic nutritional deficiencies; hormone imbalances; unhealthy lifestyle habits; bacterial infection; toxic exposure to cigarette smoke, air pollution or other substances; excessive alcohol consumption; sun exposure or bacterial infection can play a role in whether or not disease develops. Over time, these harmful agents and conditions can switch on a gene’s ability to promote disease.

Whether or not you choose to inspect your genes, they are always there and will continue to play an important role in your health. By choosingto look at them, you have the opportunity to influence the ultimate outcome and more actively promote a healthy life. You then will be empowered to modify the expression of disease years before a condition might otherwise develop.

Genomic testing is available to identify your predisposition to the following diseases:

  • Heart disease
  • Arthritis
  • Allergies
  • Osteoporosis
  • Toxicity
  • Oxidative stress
  • Anxiety
  • Cancer
  • Adverse drug reactions

Pregnancy and Preconception

Nutrition

An optimal balance of essential fatty acids is critical for a healthy pregnancy and neurologic development of the fetus. See sections on Fatty Acids, Vitamins & Antioxidants, and Minerals.

Female Hormones

Analysis of progesterone, testosterone and estradiol over a 28 day cycle provides insight into the ovulation.

Adrenal Hormones

High levels of cortisol and stress can lead to physical difficulties during pregnancy.

Heavy Metal Toxicity

Exposure to toxic metals is a risk factor for fetal development.

Thyroid Testing

Thyroid testing allows the practitioner to pinpoint common imbalances that underlie a broad spectrum of chronic illness. Thyroid hormones are essential and primary regulators of the body’s metabolism.

Imbalances can affect virtually every metabolic process in the body, exerting significant effects on mood and energy level.Thyroid imbalances may elicit fatigue, depression, coldness, constipation, poor skin, headaches, PMS, dysmenorrhea, fluid retention, weight gain, anxiety/panic attacks, decreased memory and concentration, muscle and joint pain, and low sex drive.

Thyroid function has a profound impact on overall health via: modulation of carbohydrate, protein and fat metabolism; vitamin utilization; mitochondrial function; digestive process; muscle and nerve activity; blood flow; oxygen utilization; hormone secretion; sexual and reproductive health; and many other physiological parameters.

Ensuring healthy thyroid function is clinically essential. Optimal thyroid function may help safeguard against the pathogenesis of diabetes, obesity, heart disease, and depression.

Thyroid hormones also play central metabolic roles in healthy sexual and reproductive function in both women and men. Because they are essential for IGF-1 production, thyroid hormones significantly affect lipid metabolism.

A thorough analysis of thyroid hormone metabolism includes central thyroid gland regulation and activity, thyroid production and secretion, peripheral thyroid conversion, and thyroid autoimmunity.

T3, T4

Unbound levels of T4 and T3 which reflect the bioactive portion of thyroid hormone. This assessment can identify not only overt hyper-and hypothyroidism, but subtle sub-clinical manifestations of thyroid dysfunction.

Reverse T3

Reverse T3 levels of which can increase when peripheral conversion of T4 to active T3 is impaired. Peripheral thyroid imbalances may arise from nutrient shortages, heavy metal exposure, adrenal stress, enzyme deficiencies, and other chronic illness.

Thyroid AutoImmunity

Thyroid antibody levels which help gauge autoimmune response and may reflect metabolic irregularities and hypothyroidism even when TSH and T4 levels appear normal. Thyroid antibody levels may rise in response to trauma, dysbiosis, inflammation (including thyroiditis) or progressive thyroid degeneration.

Environmental Toxin Exposure

2-methylhippurate

One of the most common organic compounds in our environment is xylene. Produced from coal tar or crude oil, xylene is used as a solvent for paints and paint thinners, and its vapors are released from many building and decorating materials such as varnishes and new carpets. Excretion of 2-methylhippurate is a sensitive and specific marker for xylene exposure.

Glucarate

Glucarate, on the other hand, serves as a biomarker for your exposure to a wide array of potentially toxic chemicals. High urinary glucarate suggests above normal exposure to pesticides, herbicides, fungicides, petrochemicals, alcohol, pharmaceutical compounds, or toxins produced in the gastrointestinal tract. Heavy metals that can be toxic to the body include aluminum, arsenic, cadmium, lead, and mercury. As mentioned earlier, the minerals zinc and selenium offer protection against cadmium and mercury respectively. Your healthcare provider may discuss options with you for heavy metal removal if deemed necessary.

Urinary Porphyrins Analysis

Porphyrins are involved in the production of heme which is a necessary ingredient of the P450 enzymes which are critical for detoxification of chemicals and toxins including pesticides. Heme is also necessary to remove beta-amyloid plaques from the brain. In a recent study, children with severe autism secreted 2-3 times more beta-amyloid precursor protein than children without autism. To generate heme, via specific enzymes, the body normally converts one species of heme porphyrin to another, in a sequential metabolic order or pathway. Yet, certain metals, particularly toxic metals such as mercury, lead, and arsenic, will inhibit different enzymes of the heme porphyrin pathway and will thus cause different and specific porphyrin patterns (or “profiles”) in the urine, the analysis of which can help us determine which metal is involved, and to what degree. Dan Rossignol, MD Paper on Porphyrins in Autism.

Vitamins and Anti-Oxidants

Vitamins are compounds that your body must have to be healthy. Vitamins are “essential” for proper function, which means they are not made inside your body and must be consumed in the diet. Your body needs vitamins for many reasons. Without them, organs cannot function properly, skin ages rapidly, and vision fails.

Vitamin D

Vitamin D is well known for the role it plays in regulating calcium and phosphorus to maintain bone health. Vitamin D insufficiency has been linked to depression and Seasonal Affective Disorder, neurological autoimmune processes, and in preventing on-going inflammation that damages tissue.

Antioxidant Vitamins

Antioxidant deficiency accelerates the process of aging and the risk of developing chronic diseases. To determine your need for antioxidant vitamins we assess both your levels of specific antioxidant vitamins and markers of oxidative stress. Vitamins A, C, and E and the nutrients beta-carotene and coenzyme Q10 are grouped together because they are all involved in antioxidant protection. The principal membrane antioxidant is vitamin E. The lipid peroxide and 8-hydroxy- 2’-deoxyguanosine levels included in the ION profile are indicators of how much damage your body may be sustaining due to lack of antioxidant protection.

Vitamin A

Every day you lose some vitamin A because it is used in the replacement of old tissues. Vitamin A is an antioxidant in the membranes of your cells where it serves a protective function. Vitamin A is required by the eye for vision and it is also needed to protect the rest of your body from damaging effects of infection and stress. However, too much vitamin A can be dangerous, particularly during pregnancy. If your levels are too high, the recommended intake range will be zero. Betacarotene, which also protects tissue, is converted by your body to vitamin A on an as-needed basis. Supplementation with beta-carotene is a safer alternative than vitamin A. Lipid peroxides indicate damage to cell membranes from oxidation. 8-hydroxy-2’-deoxyguanosine measures the oxidative impact to DNA. The lipid peroxide and 8-hydroxy-2’-deoxyguanosine levels will be high if your total antioxidant protection is inadequate. If these markers are high and vitamin A is normal, then either you need other specific antioxidants (see below) or you have a high rate of free radical oxidant production.

Vitamin C

Vitamin C is easily lost from the body and must be replaced frequently. Many experts agree that the average healthy person needs a minimum of 100-150 mg of vitamin C per day to stay healthy. Diseases and other stresses increase your need for vitamin C. Inadequate vitamin C is one factor leading to elevated lipid peroxides. Elevated 8-hydroxy-2’- deoxyguanosine indicates oxidation and need for vitamin C protection. Extra vitamin C is one way to combat the effects of elevated blood levels of toxic heavy metals like mercury, cadmium, or lead. If the cell regulator that uses vitamin C (p-hydroxyphenyllactate) is high, you may need much higher vitamin C intake (up to bowel tolerance doses) to restore normal metabolism and cell control. We measure vitamin C status indirectly with p-hydroxyphenyllactate because vitamin C degrades very rapidly and therefore cannot be measured accurately in a blood specimen sent to the laboratory.

Vitamin E

Vitamin E is a major part of your protection from daily wear and tear. It works to remove harmful molecules that degrade the fatty acids that make up cell membranes (i.e., arachidonic acid). Conditions that increase oxidative metabolism tend to raise your requirements for vitamin E. High levels of p-hydroxyphenyllactate, 8-hydroxy-2’-deoxyguanosine, and quinolinate are associated with increased oxidative stress. Significant elevations in one or more of these compounds could indicate a strong need for other antioxidants as well. The amount of vitamin E that is best for you, again, is influenced by the results of your lipid peroxide test and your serum vitamin E levels.

Coenzyme Q10

Since your body can make coenzyme Q10, it is not called a vitamin. If you are making enough to meet the demands of your tissues, you do not need to take any extra. However, many people do not make enough coenzyme Q10. Certain drugs have been shown to block coenzyme Q10 production. Elevated lipid peroxides may indicate a need for coenzyme Q10. High hydroxymethylglutarate can reveal a block in your body’s synthesis of coenzyme Q10. Other functional markers, such as lactate, succinate, fumarate, and malate, indicate whether your body is able to produce energy efficiently by utilizing coenzyme Q10.

B-Complex Vitamins

The B-complex vitamins are necessary for many enzymes in your body to function properly. Your body uses enzymes to extract energy from food, build new tissue, remove toxins, and maintain the immune system.

Vitamin B1, B3, and B5

Vitamins B1 (thiamin), B3 (niacin), and B5 (pantothenic acid) are some of the most easily lost vitamins. All kinds of stressors, both emotional and physical, can increase losses of B vitamins. Vitamins B1, B3, and B5 are necessary for energy pathways of all of the cells in your body. B vitamins are required for proper breakdown and metabolism of the food you eat. Such steps occur in carbohydrate breakdown where pyruvate and lactate are formed. Amino acids form -ketoisovalerate, -ketoisocaproate, and -keto-ß-methylvalerate, which require B vitamins for further breakdown. Carbohydrates and amino acids share a common B-vitamin-dependent step where -ketoglutarate is formed. If you have a pattern of high levels of these compounds, you may need increased intake of vitamins B1, B3, and B5.

Vitamin B2

Dietary fat, carbohydrate, and protein are all broken down to produce energy using pathways that require vitamin B2 (riboflavin). If you do not have sufficient riboflavin, compounds such as succinate, adipate, suberate, and ethylmalonate are found high in urine. Some of these compounds also give information about other micronutrients that are discussed below.

Vitamin B6

Your body needs vitamin B6 (pyridoxine) to utilize amino acids derived from dietary protein. Inadequate vitamin B6 is one factor that leads to increased concentrations of kynurenate and xanthurenate in urine. These products of amino acid breakdown cannot be further metabolized in the absence of vitamin B6. Abnormal levels of kynurenate can have direct effects on brain function in addition to showing a need for vitamin B6. Glutamine, isoleucine, and leucine are other amino acids that serve as marker compounds for vitamin B6. Deficiency of vitamin B6 can result in high levels of these amino acids. Vitamin B6 deficiency may also result in elevated concentrations of homocysteine in blood, which leads to increased risk of heart disease.

Vitamin B12 and Folic Acid

The most common dietary deficiency leading to homocysteine elevation and the associated increase in heart disease risk involves vitamin B12 and folic acid. You can have normal blood levels of these vitamins but still not have enough for your body’s enzymes to function properly. Dietary deficiency of vitamin B12 and folic acid are associated with increased risk of many diseases, including anemia and the associated chronic fatigue. Methylmalonate is a sensitive functional marker for vitamin B12; high levels of methylmalonate indicate vitamin B12 deficiency. The odd numbered fatty acids containing 15, 17, 19, or 21 carbon atoms (heptadecanoic acid, nonadecanoic acid, tricosanoic acid, pentadecanoic acid) accumulate in vitamin B12 deficiency. Formiminoglutamate (abbreviated FIGLU) is a compound made from the amino acid histidine. Insufficiency of folic acid leads to high urinary FIGLU. Folic acid is especially critical for prenatal and childhood development. It is important for lowering your risk of cardiovascular disease and cancer.

Biotin

Until recently, biotin deficiency was very difficult to determine in humans because this vitamin deficiency affects health in ways that mimic many other conditions. Doctors were likely to overlook biotin deficiency until this test was discovered. Beta(ß)-hydroxyisovalerate is a specific and sensitive metabolic marker for functional biotin deficiency. As your biotin intake decreases, your ß-hydroxyisovalerate excretion increases.

Lipoic Acid

Alpha-lipoic acid (lipoic acid) is classified as a “vitamin-like” compound. It is sulfur containing and is involved in energy metabolism, antioxidant protection, and insulin function. It protects cell membranes by interacting with vitamin C and glutathione. Lipoic acid has been studied as an adjunct therapy for diabetes and liver disease. The urinary markers, pyruvate and lactate, when elevated can indicate a need for supplemental lipoic acid.

Minerals and Elements

Minerals make up about 4 to 5 percent of body weight, and not just in the skeleton! We need minerals for nerve transmission, digestion, antibody production, metabolism of nutrients, and more. The term “elemental analysis” is sometimes used because it is the chemical elements like magnesium, iron, and potassium that actually make up mineral compounds. Just about all of the chemical elements that are found in soil or seawater are present in your body. The ones found in very small amounts are called “trace elements”. Measuring mineral concentrations inside your erythrocytes (red blood cells) is one of the best ways to determine their adequacy. Minerals are important catalysts that spark many of the chemical reactions in your body.

Calcium and Magnesium

The most abundant mineral element in your body is calcium, because it is the major element in bone. Serum and red blood cell calcium, however, do not represent bone mineral content or dietary adequacy. The most extensively required element is magnesium. Erythrocyte magnesium is a measure of magnesium adequacy. Magnesium is required for conversion of the metabolic markers orotate and succinate. Some types of heart problems are aided by using the orotate form of magnesium. Because the supply and regulation of calcium and magnesium are generally linked, it is usually best to use both calcium and magnesium. Your age and sex can help to determine the best amount for supplementation. Normally, because of their role in maintaining and repairing the body, calcium and magnesium must be consumed in hundreds of milligrams per day to maintain a positive balance.

Chromium and Vanadium

The chromium and vanadium content of your erythrocytes can be accurately measured, although their levels are normally very low. The major function of chromium and vanadium is to help insulin act on your cells to regulate blood sugar. We also assess the metabolic marker of blood sugar utilization, ßhydroxybutyrate.

Copper

Copper is part of enzymes, which are proteins that help biochemical reactions occur in every cell. Copper is involved in the absorption, storage and metabolism of iron. The symptoms of a copper deficiency are similar to iron deficiency anemia. (The liver makes a special protein, ceruloplasm, to transport copper and help convert iron to a form that can be used by other tissues). Copper is utilized by most cells as a component of enzymes involved in energy production, protection of cells from free radical damage, strengthening connective tissue, and brain neurotransmitter function. Excess zinc intake can result in a copper deficiency when intake of copper is insufficient.

Manganese

Metabolic pathways used for energy production require manganese and iron. Manganese is a component of several enzymes involved in skin, bone and cartilage formation and blood glucose control. Along with iron and copper, it helps activate an important antioxidant enzyme, superoxide dismutase.

Molybdenum

The trace element molybdenum activates enzymes for building connective tissue and for toxin removal. Molybdenum functions as a cofactor for metabolism of sulfur-containing amino acids. Molybdenum should be balanced with chromium and vanadium.

Potassium

Erythrocyte potassium levels uniquely reveal your total body potassium status. Potassium is also an abundant mineral that helps keep normal water balance between the cells and body fluids. Muscle contractions, nerve impulses and blood pressure rely on availability of potassium. Excessive potassium levels in blood interfere with normal heart and nervous function and could be caused by tissue damage. Low red blood cell potassium is rare and can result from poor dietary intake, diarrhea, disease or certain medications.

Selenium

Erythrocytes are heavily loaded with protective selenium enzymes. Measuring erythrocyte selenium content is the best way to check selenium status. Selenium is required for the production of glutathione, an important antioxidant. High pyroglutamate or low sulfate levels in your urine indicate decreased levels of glutathione, which reveals a functional need for selenium. Functioning synergistically with vitamin E, selenium protects against cellular damage from oxygen radicals. Thyroid hormone activation relies on the presence of sufficient selenium.

Zinc

Approximately 100 enzymes that support biochemical reactions in the body rely on zinc. Zinc is needed for wound healing, a healthy immune system, a healthy sense of taste and smell, and for sexual maturation and development in children. The fatty acid LA/DGLA (linolenic acid/dihomogammalinolenic acid) and ALA/EPA (alpha linolenic acid/eicosapentaenoic acid) ratio are markers that indicate functional zinc deficiency. Zinc also provides protection against the toxic metal cadmium.

Amino Acids

When dietary protein is digested and absorbed, amino acids flow into the blood stream. Amino acids have many important functions in the body including the regulation of muscle and hormone activity and the formation and maintenance of every tissue in your body (i.e., bone, ligaments, tendons, muscle). Conditions like chronic stress, depression, and toxic chemical exposure increase your need for essential amino acids. Essential amino acids are those that must be provided by the diet because the body cannot make them.

Essential Amino Acids

Supplementing essential amino acids can greatly benefit people who have low protein diets, have trouble adequately digesting protein or who have increased demand for specific amino acids to maintain body processes. Between meals, amino acids supply energy to keep cells functioning. There are certain situations where specific amino acids are recommended to supplement based on particular metabolic needs. For most people, the safest and most effective way of supporting your diet with amino acids is to take a balanced formula based upon your amino acid profile. The table that follows your vitamin and mineral recommendations describes a formula that can help meet your special needs. This table is based on your levels of essential amino acids in blood plasma. The following essential and conditionally essential amino acids are measured: arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. The additional 10 amino acids that are measured can be produced in your body if these amino acids are adequately supplied. The energy pathways in your cells require the key compounds citrate, -ketoglutarate, and succinate, which are formed from essential amino acids. Low levels of citrate, -ketoglutarate, and succinate may indicate amino acid imbalances that can affect your energy pathways.

5 – Hydroxytryptophan

Tryptophan is an essential amino acid required for the production of the neurotransmitter serotonin. 5-hydroxytryptophan (5-HTP) is an intermediate amino acid derivative in this process. Acting as a neurotransmitter, serotonin controls functions relating to mood, behavior, appetite, and sleep. The compound 5–hydroxyindoleacetate (5–HIA) is measured in urine as a marker of serotonin metabolism. When this compound is elevated, it indicates higher than normal turnover of serotonin with potential depletion of tryptophan as a result. Low levels of 5-HIA may indicate inadequate production of serotonin. 5-HTP can be used as a dietary supplement to increase production of serotonin as therapy for individuals who are depressed, have sleep problems, or chronic pain such as fibromyalgia. Serotonin re-uptake inhibitors (Prozac, Zoloft, etc.) often lead to elevated 5–HIA.

Arginine

Arginine is a conditionally essential amino acid that is critical for your cardiovascular health and detoxification functions. The amino acid arginine is used to make the powerful blood vessel regulator nitric oxide. Nitric oxide acts to lower blood pressure. Too little arginine can lead to high blood pressure. Too much arginine can lead to increased aging from oxidative damage. Arginine is measured in blood and markers of arginine insufficiency are measured in urine. High citrate, isocitrate, cis-Aconitate, or orotate can indicate arginine insufficiency. The essential amino acid lysine needs to be present in amounts balanced with arginine to ensure healthy immune system function

Carnitine

Although not an essential amino acid, carnitine helps your body use fatty acids for energy. The body makes small amounts of carnitine, but if it is not enough, fatty acids are not processed normally, and urinary excretion of the by-products adipate and suberate increases . Ethylmalonate, which comes from a different carnitine-dependent pathway, would also accumulate with carnitine insufficiency.

Glycine

Glycine is an amino acid serving several important purposes within the body, including detoxification, DNA formation, the synthesis of hemoglobin, and as a part of brain neurotransmission pathways. Glycine and serine are interchangeable . Low plasma levels of glycine and serine can serve as markers for long term repletion of essential amino acids. In the liver, glycine helps to convert many potentially harmful substances, including toxic materials such as benzoic acid (benzoate) into harmless forms. If urinary benzoate levels are elevated, it suggests you may benefit from extra glycine. A second detoxification role of glycine is to serve as a necessary part of glutathione, a compound needed by the liver. Urinary pyroglutamate and a-hydroxybutyrate levels reflect glutathione demand and availability to the body that improves when extra glycine is provided.

N-Acetylcysteine

Glutathione is constantly used up in the removal of toxic molecules and prevention of oxidative damage. Elevated levels of a-hydroxybutyrate indicate increased production of glutathione. Elevated levels of the marker pyroglutamate reveal that glutathione is being lost at a high rate. Sulfate excretion is another way to check your total body sulfur-containing amino acid status. Low urinary sulfate is an indication that total body glutathione is low and sulfur-containing amino acids are needed. The amino acid N-acetylcysteine is one agent for effectively raising your glutathione and sulfate levels.

Fatty Acids

Only in the last century have we discovered that some fats are absolutely essential to health. Our bodies cannot make these fats, and so we must get them from our food, or our health will suffer. These Essential Fatty Acids (EFAs) have many functions in the body: they are the precursors for local “hormones”; they regulate all inflammation as well as all smooth muscle contraction and relaxation. These local hormones are given names like prostaglandins, leukotrienes and thromboxanes. EFAs are also essential components for all cell membranes. Their importance for health cannot be overemphasized since the brain, nerves, eyes, connective tissue, skin, blood vessels, and every cell in the body depend on a proper balance of essential fatty acids for optimal function. It is the fats found in red blood cell membranes, known as phospholipids.

Fat is necessary for cell membranes, nerve coverings, hormone production, vitamin absorption, and more. Most of us get a lot of fat in our diet, but it usually is not the quality fat we should be getting. We need to eat more “good” fats from fish, flax seed, olive, vegetable, and nut oils (omega- 3, 6, and 9 fats respectively) and less saturated oils and trans fats (or hydrogenated oils) contained in processed foods. Elevations in palmitelaidic and/or total C:18 trans indicate excessive intake of foods containing trans fats. Palmitic and stearic acids are significant markers for high consumption of saturated fats. The families of healthy fats called omega-3, omega-6, and omega- 9 protect against heart disease and help skin and joints stay young and supple. Hydrogenated and partially hydrogenated oils often contained in shortening, margarine, and many baked goods, as well as excessive dietary saturated fats from animal products, can cause health problems on a cellular level and increase heart disease risk. The fatty acid profile shows the balance of fats and their metabolites in plasma. Your overall balance of omega-3 and omega-6 fats is represented by the ratios of AA/EPA (arachidonic acid/eicosapentaenoic acid) and EPA/DGLA (eicosapentaenoic acid/dihomogammalinolenic acid). Overall need for polyunsaturated fatty acids is best represented by Mead acid and the triene/tetraene ratio. This ratio is calculated by dividing Mead acid by arachidonic acid values. The saturated/unsaturated ratio shows the overall balance of these classes of fatty acids. It can help give a more complete picture of essential fatty acid status. How healthy is the fat you’re giving your body?

Essential fatty acids are classified into fat “families”: omega 3 fats and omega 6 fats. Non-essential fat “families” include omega-9 fats, saturated fats, omega-7 fats, and trans-fats. Optimal health depends on the proper balance of all fats – both essential and non-essential fats – in the diet. Proper balance means adequate amounts of each individual fat, without having too much, and maintaining proper balance between the various “families” of fats. Fat health also means avoiding potentially harmful fats such as trans fats found in shortening, margarine, fried foods and dairy. A proper balance of fatty acids will lead to mental health and proper nerve function, a healthy heart and circulatory system, reduced inflammation in general, proper gastrointestinal and lung function, a more balanced immune system, and even healthy skin, hair and nails. Fatty acid balance is also critical for the health of all pregnant women and their babies since the developing brain and nervous system of the baby requires large amounts of EFAs that must come from the mother. Fatty acid imbalances have been seen in many disease processes including heart disease, hypertension, insulin resistance and diabetes, asthma, painful menstruation, pre-menstrual syndrome (PMS), depression, attention deficit hyperactivity disorder (ADHD), senility, obsessive-compulsive disorder, and post-partum depression.

Fish Oil and Flaxseed Oil (Polyunsaturated Omega-3 Fatty Acids)

This family begins with alpha linolenic acid (ALA). ALA is an “essential” fatty acid (EFA), meaning that your body cannot make it and you must obtain it from your diet. ALA may be converted into eicosapentaenoic acid (EPA), a longer fatty acid that is involved in regulation of inflammatory processes and prevention of platelet “stickiness.” Diminished platelet stickiness reduces the blood clotting that can lead to heart attack or stroke. Your body can make the other polyunsaturated omega-3 fatty acids from ALA. However, many things can interfere with this process including zinc deficiency, alcohol, obesity, and aging. Docosahexaenoic acid (DHA) is another omega-3 fatty acid and is integral to brain development in fetuses and infants. The best-known sources of omega-3 fatty acids are cold-water fish, flaxseed, soybean, walnuts and their oils.

Black Currant Seed Oil (Polyunsaturated Omega-6 Fatty Acids)

Linoleic acid (LA) is another “essential” fatty acid (EFA). It is used to make the major membrane polyunsaturated fatty acid arachidonic acid (AA). High LA relative to other essential fatty acids leads to products that favor inflammatory processes and excessive amounts can lead to cardiovascular disease. Your body can make other omega-6 fatty acids from LA, like gamma linoleic acid (GLA), but this process can be blocked by nutrient deficiencies, alcohol abuse, obesity, and aging similarly to omega-3 production pathways mentioned above.

Olive Oil (Monounsaturated Fatty Acids)

Monounsaturated fatty acids are found in foods such as nuts, olives, and their oils. You can get oleic acid by using olive oil or your body can produce it from saturated fatty acids. Either way, you need this type of fat to build cell membranes that function properly. The other monounsaturated fatty acids measured are usually minor components. They may reveal metabolic imbalances that affect nerve function and cellular energy production.
