Deficiency Symptoms - Vitamins, NutrientsThymus Extracts
Thymus Extracts Deficiency SymptomsSince it is not an essential nutrient, no deficiency state exists. Thyroid Extracts
Thyroid Extracts Deficiency SymptomsAs thyroid extract is not an essential nutrient, therefore, no deficiency state exists. Glucomannan
Glucomannan Deficiency SymptomsAs glucomannan is not an essential nutrient, no deficiency state exists. Glucosamine
Glucosamine Deficiency SymptomsA glucosamine deficiency in humans has not been reported. Glutathione
Glutathione Deficiency SymptomsA deficiency can be the result of diseases that increase the need for glutathione, deficiencies of the amino acids needed for synthesis, or diseases that inhibit glutathione formation. Examples of some health conditions that are associated with glutathione deficiency include diabetes, low sperm counts, liver disease, cataracts, and HIV infection, respiratory distress [...] Proanthocyanidins
Proanthocyanidins Deficiency SymptomsFlavonoids and proanthocyanidins are not classified as essential nutrients because their absence does not induce a deficiency state. However, proanthocyanidins may have many health benefits, and anyone not eating the various plants that contain them would not derive these benefits. Grapefruit Seed Extract
Grapefruit Seed Extract Deficiency SymptomsGrapefruit seed extract is not an essential nutrient and no deficiency states have been reported. Green-Lipped Mussel
Green-Lipped Mussel Deficiency SymptomsBecause green-lipped mussel is not an essential nutrient, deficiencies do not occur. Huperzia
Huperzia Deficiency Symptoms Hyaluronic Acid
Hyaluronic Acid Deficiency SymptomsHyaluronic acid is produced naturally in the human body and is not considered an essential nutrient. However, hyaluronic acid levels in osteoarthritic joints are below normal. Indole-3-Carbinol
Indole-3-Carbinol Deficiency SymptomsAs indole-3-carbinol is not an essential nutrient, no deficiency state exists. Inosine
Inosine Deficiency SymptomsInosine is not an essential nutrient, so deficiencies do not occur. Inositol
Inositol Deficiency SymptomsClear deficiency of inositol has not been reported, although people with diabetes have increased excretion and may benefit from inositol supplementation. Vitamin B3
Vitamin B3 Deficiency SymptomsPellagra, the disease caused by a vitamin B3 deficiency, is rare in Western societies. Symptoms include loss of appetite, skin rash, diarrhea, mental changes, beefy tongue, and digestive and emotional disturbance. IP-6
IP-6 Deficiency SymptomsWhile there is no dietary requirement for IP-6, people consuming diets low in dietary fiber and nuts and seeds have the lowest intake. Iodine
Iodine Deficiency SymptomsPeople who avoid dairy, seafood, processed food, and iodized salt can become deficient. Iodine deficiency can cause low thyroid function, goiter, and cretinism. Although iodine deficiencies are now uncommon in Western societies, the U.S. population has shown a trend of significantly decreasing iodine intake from 1988–1994. If this trend continues, iodine deficiency diseases may become more common. [...] Ipriflavone
Ipriflavone Deficiency SymptomsAs ipriflavone is not an essential nutrient, no deficiency state exists. Lysine
Lysine Deficiency SymptomsMost people, including vegans (vegetarians who also avoid dairy and eggs), consume adequate amounts of lysine. However, vegans whose diets contain large amounts of grains and only minimal amounts of beans could become deficient in lysine. Athletes involved in frequent vigorous exercise have increased need for essential amino acids, although most diets [...] Magnesium
Magnesium Deficiency SymptomsMagnesium deficiency is common in people taking “potassium-depleting” prescription diuretics. Taking too many laxatives can also lead to deficiency. Alcoholism, severe burns, diabetes, and heart failure are other potential causes of deficiency. In a study of urban African-American people (predominantly female), the overall prevalence of magnesium deficiency was 20%. People with a [...] Malic Acid
Malic Acid Deficiency SymptomsA deficiency in humans is unlikely, since the body can produce malic acid. Manganese
Manganese Deficiency SymptomsMany people consume less than the 2–5 mg of manganese currently considered safe and adequate. Nonetheless, clear deficiencies are rare. People with osteoporosis sometimes have low blood levels of manganese, suggestive of deficiency. Medium-Chain Triglycerides
Medium-Chain Triglycerides Deficiency SymptomsMost people consume adequate amounts of fat in their diets and many people consume excessive amounts, so extra fat intake as medium-chain triglycerides is unnecessary. Melatonin
Melatonin Deficiency SymptomsAlthough elderly people often have difficulty sleeping and melatonin supplements have been shown to improve sleep in the elderly, melatonin secretion does not appear to decline in healthy older adults to a significant degree, despite many preliminary reports to the contrary. Most of these preliminary studies failed to verify that older subjects were healthy and not using drugs [...] Multiple Vitamin-Mineral Supplements
Multiple Vitamin-Mineral Supplements Deficiency Symptoms Molybdenum
Molybdenum Deficiency SymptomsAlthough molybdenum is an essential mineral, no deficiencies have been reported in humans. N-Acetyl-Glucosamine
N-Acetyl-Glucosamine Deficiency SymptomsAs NAG is not an essential nutrient, no deficiency states have been reported. NADH
NADH Deficiency SymptomsNADH deficiency is known to occur only in the presence of vitamin B3 deficiency, which is rare in Western society except in some alcoholics. Ionized Air (Negative Ions)
Ionized Air (Negative Ions) Deficiency Symptoms Octacosanol
Octacosanol Deficiency SymptomsBecause octacosanol is not an essential bodily constituent, deficiencies do not occur. Ornithine Alpha-Ketoglutarate
Ornithine Alpha-Ketoglutarate Deficiency SymptomsA deficiency of OKG has not been reported. PABA
PABA Deficiency SymptomsDeficiencies of PABA have not been described in humans, and most nutritionists do not consider it an essential nutrient. Phosphorus
Phosphorus Deficiency SymptomsPhosphorus deficiency is uncommon, because dietary intake is usually adequate. Chronic alcoholics may become deficient in phosphorus. and people taking large amounts of aluminum-containing antacids One study has shown that taking calcium can interfere with the absorption of phosphorus, [...] Phosphatidylserine
Phosphatidylserine Deficiency SymptomsPS is not an essential nutrient, and therefore dietary deficiencies do not occur. Adults age 50 and older, especially those with age-related cognitive decline, may not synthesize enough PS, and appear most likely to benefit from supplemental PS. Vitamin K
Vitamin K Deficiency SymptomsA vitamin K deficiency, which causes uncontrolled bleeding, is rare, except in people with certain malabsorption diseases. However, there are reports of severe vitamin K deficiency developing in hospitalized patients who had poor food intake and were receiving antibiotics. [...] Policosanol
Policosanol Deficiency SymptomsPolicosanol is not an essential nutrient, so no deficiencies are possible. Potassium
Potassium Deficiency SymptomsSo-called primitive diets provided much greater levels of potassium than modern diets, which may provide too little. Gross deficiencies, however, are rare except in cases of prolonged vomiting, diarrhea, or use of “potassium-depleting”diuretic drugs. People taking one of these drugs are often advised by their doctor to take supplemental [...] Pregnenolone
Pregnenolone Deficiency SymptomsSince it is not an essential nutrient, pregnenolone is not associated with a deficiency state. Progesterone
Progesterone Deficiency SymptomsPostmenopausal women have reduced production of progesterone. While this “deficiency” is normal, progesterone, including the natural forms of progesterone, has been found to relieve menopausal symptoms when used in combination with estrogen replacement therapy. Whey Protein
Whey Protein Deficiency SymptomsPeople who do not include dairy foods in their diets do not consume whey protein. However, the amino acids in whey protein are available from other sources, and a deficiency of these amino acids is unlikely. People who do not include dairy foods in their diets do not consume whey protein. However, [...] Pyruvate
Pyruvate Deficiency SymptomsBecause it is not an essential nutrient, pyruvate is not associated with a deficiency state. Resveratrol
Resveratrol Deficiency SymptomsSince it is not an essential nutrient, resveratrol is not associated with a deficiency state. Ribose
Ribose Deficiency SymptomsRibose is not an essential nutrient, therefore deficiencies do not occur. Royal Jelly
Royal Jelly Deficiency SymptomsBecause royal jelly is not an essential nutrient, deficiencies do not occur. 7-KETO
7-KETO Deficiency SymptomsSince the level of 7-KETO is directly related to the level of DHEA in the body, people with lower DHEA levels likely have low 7-KETO levels as well. Low DHEA levels are primarily associated with aging. SAMe
SAMe Deficiency SymptomsSAMe is normally produced in the liver from the amino acidmethionine which is abundant in most diets. Folic acid and vitamin B12 are necessary for the synthesis of SAMe, and deficiencies of these vitamins results in low concentrations of SAMe in the central nervous system. Low blood or central nervous system levels of [...] Selenium
Selenium Deficiency SymptomsWhile most people probably don’t take in enough selenium, gross deficiencies are rare in Western countries. Soils in some areas are selenium-deficient and people who eat foods grown primarily on selenium-poor soils are at risk for deficiency. People with AIDS have been reported to [...] Silicon
Silicon Deficiency SymptomsSilicon is not an essential mineral. Deficiencies have not been reported. Strontium
Strontium Deficiency SymptomsStrontium is not an essential mineral, so deficiencies are not seen with this mineral. Sulforaphane
Sulforaphane Deficiency SymptomsSulforaphane is not an essential nutrient, and thus no deficiency state exists. Sulfur
Sulfur Deficiency SymptomsDeficiencies of sulfur have not been documented, although a protein-deficient diet could theoretically lead to a deficiency of sulfur. Low levels of cystine, and therefore possibly sulfur, were reported many years ago in people with arthritis, but this association is far from proven. Tocotrienols
Tocotrienols Deficiency SymptomsAs it is not an essential nutrient, no deficiency state exists. Top Anti-Aging Supplements
Top Anti-Aging Supplements Deficiency Symptoms Top Supplements for Men
Top Supplements for Men Deficiency Symptoms Vanadium
Vanadium Deficiency SymptomsDeficiencies of vanadium have not been reported in humans, and it is not known whether this mineral is essential for humans. Vinpocetine
Vinpocetine Deficiency SymptomsVinpocetine is not an essential nutrient, so no deficiencies are possible. Xylitol
Xylitol Deficiency SymptomsXylitol is not an essential nutrient; therefore, no deficiencies are possible. Zinc
Zinc Deficiency SymptomsZinc deficiencies are quite common in people living in poor countries. Phytate, a substance found in unleavened bread (pita, matzos, and some crackers) significantly reduces absorption of zinc, increasing the chance of zinc deficiency. However, phytate-induced deficiency of zinc appears to be a significant problem only for people already consuming [...] Vitamin A
Vitamin A Deficiency SymptomsPeople who limit their consumption of liver, dairy foods, and beta-carotene-containing vegetables can develop a vitamin A deficiency. Extremely low birth weight babies (2.2 pounds or less) are at high risk of being born with a deficiency, and vitamin A shots given to these [...] Acetyl-L-Carnitine
Acetyl-L-Carnitine Deficiency SymptomsAcetyl-L-carnitine levels may decrease with advancing age. However, because it is not an essential nutrient, true deficiencies do not occur. N-Acetyl Cysteine
N-Acetyl Cysteine Deficiency SymptomsDeficiencies of NAC have not been defined and may not exist. Deficiencies of the related amino acidcysteine have been reported in HIV-infected patients. Probiotics
Probiotics Deficiency SymptomsPeople using antibiotics, eating a poor diet, or suffering from diarrhea are more likely to have depleted colonies of friendly bacteria. Silica Hydride
Silica Hydride Deficiency SymptomsSilica hydride is not an essential nutrient, so no deficiencies are possible. Adenosine Monophosphate
Adenosine Monophosphate Deficiency SymptomsPreliminary research suggests that people with herpes simplex or herpes zoster (shingles) infections may have low levels of AMP; however, the clinical significance of this finding is unclear. Vitamin B12
Vitamin B12 Deficiency SymptomsVegans (vegetarians who also avoid dairy and eggs) frequently become deficient, though the process often takes many years. People with malabsorption conditions, including those with tapeworm infestation and those with bacterial overgrowth in the intestines, often suffer from vitamin B12 deficiency. Malabsorption of [...] Adrenal Extract
Adrenal Extract Deficiency SymptomsAs adrenal extract is not an essential nutrient, no nutritional deficiency state exists. However, some people sub-optimal adrenal function or frank adrenal insufficiency. The diagnosis of adrenal problems should be made by a physician. Alpha Lipoic Acid
Alpha Lipoic Acid Deficiency SymptomsAlthough alpha lipoic acid was thought to be a vitamin when it was first discovered, subsequent research determined that it is created in the human body and thus is not an essential nutrient. For this reason, deficiencies of alpha lipoic acid are not known [...] Alanine
Alanine Deficiency SymptomsSince alanine is synthesized in the body and is also provided by most foods that are sources of protein, deficiencies are unlikely to occur. Alfalfa
Alfalfa Deficiency Symptoms Blue-Green Algae
Blue-Green Algae Deficiency SymptomsAs it is not an essential nutrient, blue-green algae is not associated with a deficiency state. However, people who do not consume several servings of vegetables per day could benefit from the carotenoids and other nutrients in blue-green algae. Since it is a complete protein, it can [...] Aloe
Aloe Deficiency Symptoms Alpha Ketoglutarate (AKG)
Alpha Ketoglutarate (AKG) Deficiency SymptomsAKG is not an essential nutrient, and no deficiency has been reported. Vitamin E
Vitamin E Deficiency SymptomsSevere vitamin E deficiencies are rare. People with a genetic defect in a vitamin E transfer protein called thrombotic thrombocytopenic purpura (TTP) have severe vitamin E deficiency, characterized by low blood and tissue levels of vitamin E and progressive nerve [...] Amino Acids Overview
Amino Acids Overview Deficiency SymptomsThe vast majority of Americans eat more than enough protein and also more than enough of each essential amino acid for normal purposes. Dieters, some strict vegetarian body builders, and anyone consuming an inadequate number of calories may not [...] 5-Hydroxytryptophan
5-Hydroxytryptophan Deficiency SymptomsDisruptions in emotional well-being, including depression and anxiety, have been linked to serotonin imbalances in the brain. People with fibromyalgia often have low serotonin levels in their blood. Supplements of 5-HTP may increase serotonin synthesis in these cases. The cause of migraine headaches is [...] Arginine
Arginine Deficiency SymptomsNormally, the body makes enough arginine, even when it is lacking in the diet. However, during times of unusual stress (including infection, burns, and injury), the body may not be able to keep up with increased requirements. Branched-Chain Amino Acids
Branched-Chain Amino Acids Deficiency SymptomsOnly a person deficient in protein would become deficient in BCAAs, because most foods that are sources of protein supply BCAAs. Few people in Western societies are protein deficient. L-Carnitine
L-Carnitine Deficiency SymptomsCarnitine deficiencies are rare, even in strict vegetarians, because the body produces carnitine relatively easily. Rare genetic diseases can cause a carnitine deficiency. Also, deficiencies are occasionally associated with other diseases, such as diabetes and cirrhosis. Among people with diabetes, carnitine deficiency is more likely to be found in persons [...] Cysteine
Cysteine Deficiency SymptomsAccording to several studies, blood levels of cysteine and glutathione are low in people infected with HIV. Cysteine has a role in the proper function of the immune system, so a deficiency of this amino acid may either contribute to, or result from, immune suppression associated with HIV. Phenylalanine
Phenylalanine Deficiency SymptomsPeople whose diets are very low in protein may develop a deficiency of LPA, although this is believed to be very uncommon. However, one does not necessarily have to be deficient in LPA in order to benefit from a DLPA supplement. Glutamic Acid
Glutamic Acid Deficiency SymptomsMost food sources of protein supply glutamic acid, so only a person deficient in protein would become deficient in glutamic acid. Glutamine
Glutamine Deficiency SymptomsFew healthy people are glutamine deficient, in part because the body makes its own. During fasting, starvation, cirrhosis, critical illnesses in general, and weight loss associated with AIDS and cancer, however, deficiencies often develop. Glycine
Glycine Deficiency SymptomsFew people are glycine deficient, in part because the body makes its own supply of the nonessential amino acids. Histidine
Histidine Deficiency SymptomsAccording to limited research, many people with rheumatoid arthritis have low levels of histidine. Taking histidine supplements might improve arthritis symptoms in some people. L-Tyrosine
L-Tyrosine Deficiency SymptomsSome people affected by PKU are deficient in tyrosine. Tyrosine levels are occasionally low in depressed people. Any person losing large amounts of protein, such as those with some kidney diseases, may be deficient in several amino acids, including tyrosine. Methionine
Methionine Deficiency SymptomsMost people consume plenty of methionine through a typical diet. Lower intakes during pregnancy have been associated with neural tube defects in newborns, but the significance of this is not yet clear. Ornithine
Ornithine Deficiency SymptomsSince ornithine is produced by the body, a deficiency of this nonessential amino acid is unlikely, though depletion can occur during growth or pregnancy, and after severe trauma or malnutrition. Taurine
Taurine Deficiency SymptomsMost people, including vegans (vegetarians who eat no dairy or eggs), do not need taurine supplements. While infants require taurine, the amount in either human milk or formula is adequate. People with diabetes have been reported to have lower blood levels of taurine than non-diabetics. Amylase Inhibitors
Amylase Inhibitors Deficiency SymptomsAmylase inhibitors are not essential nutrients and are not normally produced in the body, so no deficiency is possible. Antioxidants and Free Radicals
Antioxidants and Free Radicals Deficiency Symptoms Arginine AKG (NO2 Compound)
Arginine AKG (NO2 Compound) Deficiency SymptomsA deficiency of AAKG has not been reported. Kelp
Kelp Deficiency SymptomsPeople who avoid sea vegetables, as well as dairy, seafood, processed food, and the salt shaker, can become deficient in iodine. Iodine deficiency can cause low thyroid function, goiter, and cretinism. Although iodine deficiency is now uncommon in [...] Vitamin C
Vitamin C Deficiency SymptomsAlthough scurvy (severe vitamin C deficiency) is uncommon in Western societies, many doctors believe that most people consume less than optimal amounts. Fatigue, easy bruising, and bleeding gums are early signs of vitamin C deficiency that occur long before frank scurvy develops. Smokers have low levels [...] Vitamin B-Complex
Vitamin B-Complex Deficiency Symptoms Vitamin B1
Vitamin B1 Deficiency SymptomsA decline in vitamin B1 levels occurs with age, irrespective of medical condition. Deficiency is most commonly found in alcoholics, people with malabsorption conditions, and those eating a very poor diet. It is also common in children with congenital heart disease. People [...] Vitamin B2
Vitamin B2 Deficiency SymptomsVitamin B2 deficiency can occur in alcoholics. Also, a deficiency may be more likely in people with cataracts or sickle cell anemia. In developing countries, vitamin B2 deficiency has been found to be a risk factor for the development of preeclampsia in pregnant women. People with chronic fatigue syndrome may be deficient [...] Pantothenic Acid
Pantothenic Acid Deficiency SymptomsPantothenic acid deficiencies may occur in people with alcoholism but are generally believed to be rare. Vitamin B6
Vitamin B6 Deficiency SymptomsVitamin B6 deficiencies are thought to be very rare. Vitamin B6 deficiency can cause impaired immunity, skin lesions, and mental confusion. A marginal deficiency sometimes occurs in alcoholics, patients with kidney failure, and women using oral contraceptives. Some doctors believe that most diets do not provide optimal amounts of this vitamin. [...] Folic Acid
Folic Acid Deficiency SymptomsMany people consume less than the recommended amount of folic acid. Scientists have found that people with heart disease commonly have elevated blood levels of homocysteine, a laboratory test abnormality often controllable with folic acid supplements. This suggests that many people in Western societies have a mild folic acid [...] Pollen
Pollen Deficiency SymptomsSince pollen is not an essential bodily constituent, deficiencies do not occur. Propolis
Propolis Deficiency SymptomsPropolis is not an essential nutrient and no deficiency states have been reported. HMB
HMB Deficiency SymptomsHMB is not an essential nutrient. The body creates HMB from leucine, so any diet containing sufficient amounts of leucine (most do) should lead to the adequate production of HMB. Limited evidence indicates that athletes may benefit from supplemental intake of HMB. [...] Beta-Carotene
Beta-Carotene Deficiency SymptomsPeople who limit their consumption of beta-carotene-containing vegetables could be at higher risk of developing a vitamin A deficiency. However, because beta-carotene is not an essential nutrient, true deficiencies do not occur. Nevertheless, very old persons with type 2 [...] Beta-Glucan
Beta-Glucan Deficiency SymptomsBecause beta-glucan is not an essential nutrient, deficiencies do not occur. Beta-Sitosterol
Beta-Sitosterol Deficiency SymptomsBecause beta-sitosterol is not an essential nutrient, deficiencies do not occur. Betaine (Trimethylglycine)
Betaine (Trimethylglycine) Deficiency SymptomsBetaine is not an essential nutrient, and thus no deficiency state exists. Betaine Hydrochloride
Betaine Hydrochloride Deficiency SymptomsSome research suggests that people with a wide variety of chronic disorders, such as allergies, asthma, and gallstones, do not produce adequate amounts of stomach acid. Flavonoids
Flavonoids Deficiency SymptomsFlavonoid deficiencies have not been reported. Biotin
Biotin Deficiency SymptomsCertain rare inborn diseases can leave people with depletion of biotin due to the inability to metabolize the vitamin normally. A dietary deficiency of biotin, however, is quite uncommon, even in those consuming a diet low in this B vitamin. Nonetheless, if someone eats large quantities of raw egg whites, a biotin deficiency can develop, because a protein [...] Evening Primrose Oil
Evening Primrose Oil Deficiency SymptomsThose with premenstrual syndrome, diabetes, scleroderma, Sjogren’s syndrome, tardive dyskinesia, eczema, and other skin conditions can have a metabolic block that interferes with the body’s ability to make GLA. In preliminary research, supplementation with EPO has helped people with these conditions. There is evidence that alcoholics may be deficient in GLA, and [...] Borage Oil
Borage Oil Deficiency SymptomsMany people in Western societies may be at least partially GLA-deficient as a result of aging, glucose intolerance, dietary fat intake, and other problems, though the exact incidence of deficiency remains unknown. People with deficiencies benefit from supplemental GLA intake from borage oil, black currant seed oil, or evening [...] Boric Acid
Boric Acid Deficiency SymptomsBoric acid is not taken internally and is not a nutrient; no deficiency exists. Boron
Boron Deficiency SymptomsAs boron is not yet considered an essential nutrient for humans, it is not clear whether deficiencies occur. However, diets that are low in fruit, vegetables, legumes, and nuts provide less boron than diets that contain more of these foods. Cartilage and Collagen
Cartilage and Collagen Deficiency SymptomsSince they are not essential nutrients, neither cartilage nor collagen are associated with deficiencies. Bovine Colostrum
Bovine Colostrum Deficiency SymptomsAs bovine colostrum is not an essential nutrient, no deficiency state exists. Brewer’s Yeast
Brewer’s Yeast Deficiency SymptomsBrewer’s yeast is not an essential nutrient, but it can be used as a source of B-complex vitamins and protein. It is by far the best source of chromium, both in terms of quantity and bio-availability. Bromelain
Bromelain Deficiency SymptomsSince bromelain is not essential, deficiencies of this plant-based enzyme do not exist. Vitamin D
Vitamin D Deficiency SymptomsIn adults, vitamin D deficiency may result in a softening of the bones known as osteomalacia. This condition is treated with vitamin D, sometimes in combination with calcium supplements. Osteomalacia should be diagnosed, and its treatment monitored, by a doctor. In people of any age, vitamin D deficiency causes abnormal bone formation. It [...] Calcium
Calcium Deficiency SymptomsSevere deficiency of either calcium or vitamin D leads to a condition called rickets in children and osteomalacia in adults. Since vitamin D is required for calcium absorption, people with conditions causing vitamin D deficiency (e.g., pancreatic insufficiency) may develop a deficiency of calcium as well. Vegans (pure vegetarians), people with dark skin, those who live [...] Calcium D-glucarate
Calcium D-glucarate Deficiency SymptomsCalcium D-glucarate is not an essential nutrient, and thus no deficiency state exists. Calcium: Which Form Is Best?
Calcium: Which Form Is Best? Deficiency Symptoms Carnosine
Carnosine Deficiency SymptomsCarnosine deficiency may occur in severe protein deficiency and in certain severe genetic disorders characterized by inborn errors in amino acid metabolism. Carotenoids
Carotenoids Deficiency SymptomsCarotenoid deficiency is not considered a classic nutritional deficiency like scurvy or beri-beri (severe vitamin C and vitamin B1 deficiencies, respectively). However, given the possible health benefits of carotenoids, most doctors recommend adequate intake. People who do not frequently consume carotenoid-rich foods or take carotenoid supplements are likely to be taking in less than adequate [...] Lutein
Lutein Deficiency SymptomsWhile a deficiency has not been identified, people who eat more lutein-containing foods appear to be at lower risk of macular degeneration. One study found that adults with the highest dietary intake of lutein had a 57% decreased risk of macular [...] Lycopene
Lycopene Deficiency SymptomsThis is unknown, but people who do not eat diets high in tomatoes or tomato products are likely to consume less than optimal amounts. Cetyl Myristoleate
Cetyl Myristoleate Deficiency SymptomsAs cetyl myristoleate is not an essential nutrient, no deficiency state exists. Chitosan
Chitosan Deficiency SymptomsChitosan is not an essential nutrient, so deficiencies do not occur. Chlorophyll
Chlorophyll Deficiency SymptomsBecause chlorophyll is not known to be an essential nutrient, a deficiency does not exist. People who do not eat plenty of green foods lack chlorophyll in their diets. Lecithin/Phosphatidyl Choline
Lecithin/Phosphatidyl Choline Deficiency SymptomsAlthough choline deficiencies have been artificially induced in people, little is known about human deficiency in the real world. Chondroitin Sulfate
Chondroitin Sulfate Deficiency SymptomsBecause the body makes chondroitin, the possibility of a dietary deficiency remains uncertain. Nevertheless, chondroitin sulfate may be reduced in joint cartilage affected by osteoarthritis and possibly other forms of arthritis. Glucosamine/Chondroitin
Glucosamine/Chondroitin Deficiency Symptoms Chromium
Chromium Deficiency SymptomsMost people eat less than the U.S. National Academy of Science’s recommended range of 50–200 mcg per day. The high incidence of adult-onset diabetes suggests to some doctors that many people should be supplementing with small amounts of chromium. Conjugated Linoleic Acid
Conjugated Linoleic Acid Deficiency SymptomsNo deficiencies of CLA are reported or believed to occur, since it is not an essential nutrient. Coconut Oil
Coconut Oil Deficiency SymptomsThere is no human requirement for coconut oil or the shorter-length fatty acids it contains, so no deficiency is possible. Fish Oil and Cod Liver Oil (EPA & DHA)
Fish Oil and Cod Liver Oil (EPA & DHA) Deficiency SymptomsSo-called “primitive” diets have much higher levels of EPA and DHA than modern diets. As a result, some researchers and doctors believe that most people who eat a typical western diet are likely to be [...] Coenzyme Q10
Coenzyme Q10 Deficiency SymptomsDeficiency is poorly understood, but it may be caused by synthesis problems in the body rather than an insufficiency in the diet. Low blood levels have been reported in people with heart failure, cardiomyopathy, gingivitis (inflammation of the gums), [...] Colloidal Silver
Colloidal Silver Deficiency SymptomsSilver is not an essential nutrient, and thus no deficiency state exists. Copper
Copper Deficiency SymptomsMany people consume slightly less than the “safe and adequate range” of copper, 1.5–3.0 mg per day. Little is known about the clinical effects of these marginally adequate intakes, though frank copper deficiency is uncommon. Children with Menkes’ disease are unable to absorb copper normally and become [...] Creatine Monohydrate
Creatine Monohydrate Deficiency SymptomsPeople involved in intense physical activity, especially those limiting their intake of red meat, may have low muscle stores of creatine. Several muscle diseases, as well as rheumatoid arthritis, and chronic circulatory and respiratory diseases, are associated with lowered creatine levels. Turmeric
Turmeric Deficiency Symptoms D-Mannose
D-Mannose Deficiency SymptomsAs D-mannose is not an essential nutrient, except in certain rare genetic disorders people produce sufficient amounts to provide for the bodies' needs. Soy
Soy Deficiency SymptomsAlthough deficiencies do not occur, people who do not consume soy foods will not gain the benefits of soy. Dehydroepiandrosterone (DHEA)
Dehydroepiandrosterone (DHEA) Deficiency SymptomsMeaningful levels of DHEA do not appear in food, and therefore dietary deficiency does not exist. Some people, however, may not synthesize enough DHEA. DHEA levels peak in early adulthood and then start a lifelong descent. By the age of 60, DHEA levels are only about 5–15% of what they were [...] Docosahexaenoic Acid
Docosahexaenoic Acid Deficiency SymptomsPremature infants who are not breast-fed are often DHA-deficient. A link has appeared between DHA deficiency and Alzheimer’s disease; however, no evidence at this time indicates that supplementation with DHA will help Alzheimer’s patients. Similarly, preliminary evidence shows that children with attention deficit disorder (ADD) have low DHA levels. However, no evidence demonstrates that DHA supplementation improves [...] Digestive Enzymes
Digestive Enzymes Deficiency SymptomsPeople with pancreatic insufficiency and cystic fibrosis frequently require supplemental pancreatic enzymes (which include proteolytic enzymes, lipases, and amylases). In addition, those with celiac disease or Crohn’s disease and perhaps some people suffering from indigestion may be deficient in pancreatic enzymes. As bromelain and papain are not essential, deficiencies do not exist. Methylsulfonylmethane
Methylsulfonylmethane Deficiency SymptomsAlthough MSM is present in food, it is not an essential nutrient, so deficiency is not likely. DMSO
DMSO Deficiency SymptomsDMSO is not an essential nutrient and it is not needed in the functions of a healthy body; therefore, deficiencies do not exist. DMAE
DMAE Deficiency SymptomsNo deficiencies of DMAE are reported or believed to occur. Green Tea
Green Tea Deficiency Symptoms Lactase
Lactase Deficiency SymptomsOnly one-third of all people retain the ability to digest lactose into adulthood. Most individuals of Asian, African, and Native American descent are lactose intolerant. In addition, half of Hispanics and about 20 percent of Caucasians do not produce [...] Lipase
Lipase Deficiency SymptomsPeople with pancreatic insufficiency and cystic fibrosis frequently require supplemental lipase and other enzymes. In addition, those with celiac disease or Crohn’s disease and perhaps some people suffering from indigestion may be deficient in pancreatic enzymes including lipase. Methoxyisoflavone
Methoxyisoflavone Deficiency SymptomsMethoxyisoflavone is not an essential nutrient, so no deficiencies are possible. Iron
Iron Deficiency SymptomsVegetarians eat less iron than non-vegetarians, and the iron they eat is somewhat less absorbable. As a result, vegetarians are more likely to have reduced iron stores. However, iron deficiency is not usually caused by a lack of iron in the diet alone. An underlying cause, such as iron loss [...] Fiber
Fiber Deficiency SymptomsMost people who consume a typical Western diet are fiber-deficient. Eating white flour, white rice, and fruit juice (as opposed to whole fruit) all contribute to this problem. Many so-called whole wheat products contain mostly white flour. Read labels and avoid “flour” and “unbleached flour,” both of which are simply [...] Psyllium
Psyllium Deficiency Symptoms Quercetin
Quercetin Deficiency SymptomsNo clear deficiency of quercetin has been established. Flaxseed and Flaxseed Oil
Flaxseed and Flaxseed Oil Deficiency SymptomsALA deficiencies are possible but believed to be rare, except in infants who are fed formula that is omega-3 deficient. Lignan is not an essential nutrient, so deficiencies are not possible. Fluoride
Fluoride Deficiency SymptomsAs fluoride is not considered an essential mineral, it does not have an associated deficiency state. Regardless, people living in areas with low concentrations of fluoride in the drinking water do appear to be at a higher risk of significant tooth decay than those living in areas [...] Fructo-oligosaccharides (FOS) and Other Oligosaccharides
Fructo-oligosaccharides (FOS) and Other Oligosaccharides Deficiency SymptomsAs FOS, GOS, and inulin are not essential nutrients, no deficiency state exists. Fumaric Acid
Fumaric Acid Deficiency SymptomsNo deficiencies of fumaric acid have been reported. However, some doctors suggest that people with psoriasis may have a biochemical defect that interferes with adequate fumaric acid production in the skin. GABA (Gamma-Amino Butyric Acid)
GABA (Gamma-Amino Butyric Acid) Deficiency SymptomsSome people with anxiety, panic disorders, and depression may not manufacture sufficient levels of GABA. Gamma Oryzanol
Gamma Oryzanol Deficiency SymptomsSince gamma oryzanol is not an essential nutrient, it is not associated with a deficiency state. Hydroxycitric Acid
Hydroxycitric Acid Deficiency SymptomsSince it is not an essential nutrient, HCA is not associated with a deficiency state. Garlic
Garlic Deficiency Symptoms Ginkgo biloba
Ginkgo biloba Deficiency Symptoms Glandular Extracts
Glandular Extracts Deficiency SymptomsAs glandulars are not essential nutrients, no deficiency states exist. Liver Extracts
Liver Extracts Deficiency SymptomsAs it is not an essential nutrient, no deficiency state exists. Spleen Extracts
Spleen Extracts Deficiency SymptomsAs spleen extract is not an essential nutrient, no deficiency state exists. |
