 Educational Information Biological Chromium Molybdenum Zinc


Chromium enriched yeast helps to normalize blood sugar, potentiating the action of insulin (Glucose Tolerance Factor) and plays an important role in the metabolism of fats and carbohydrates.

Chromium is an essential nutrient required for normal carbohydrate and fat metabolism. Insufficient dietary intake of chromium leads to signs and symptoms that are similar to those observed in diabetes and cardiovascular diseases.

Dietary intake of chromium in the U.S and most industrialized countries is suboptimal due to the extensive processing of our foods. The estimated and safe daily intake for chromium is 50 to 200 micrograms. Most diets, however, contain less than 60% of the minimum suggested intake. Supplemental chromium given to people with impaired glucose tolerance or diabetes leads to improved blood glucose, insulin, and lipid variables.

Strenuous exercise, high sugar diets and physical trauma result in high chromium losses and increase the need for chromium supplements. Chromium has been also shown to improve lean body mass in humans and certain animals.

A significantly increased rate of growth was observed in a group of malnourished children given a chromium supplement.

Response to chromium is dependent upon the form and the amount of supplemental chromium. Organic GTF is an excellent source of biologically active chromium.

No documented signs of chromium toxicity have been reported in the many chromium supplementation studies over the past three decades.

Nutritecks Chromium Yeast is grown from special strains of yeast on natural ingredients enriched with chromium. Primary grown high chromium yeast is reported to have significantly greater level of biologically active chromium than inorganic chromium.

High Chromium Yeast is a biologically active form of chromium and is better absorbed than inorganic chromium. High chromium yeast is the preferred form of chromium for nutrition supplements.

GLUCOSE TOLERANCE FACTOR Chromium is recognized as a trace element essential for human nutrition and it must be obtained from the diet. Chromium, as the central part of Glucose Tolerance Factor (GTF), enhances the effect of insulin in the body. This factor improves glucose tolerance and insulin efficacy. Nutritecks Organic GTF contains high levels of organic chromium that is available for GTF.

Glucose Tolerance Factor (GTF) has been shown to be related to normal carbohydrate metabolism.

Chromium deficiency in humans leads to symptoms associated with diabetes such as glucose intolerance, unexpected weight losses and impaired nerve conduction.

Chromium deficiency occurs in older individuals, diabetics and those consuming large amounts of carbohydrates and sugars. Chromium supplements are suggested for those individuals.

Insulin requiring diabetics have been shown to have an abnormal rate of chromium absorption. During the first 24 hours after a single oral dose of chromium, the individuals absorbed two or more times more chromium than normal subjects.

Chromium potentiates or enhances the action of insulin, it does not replace insulin. With an optimum level of chromium in the body, less insulin is required to keep glucose levels under control.

A study with diabetics showed that inorganic chromium was ineffective in improving glucose tolerance while a six month supplement of high chromium yeast normalized the glucose tolerance as measured by the glucose tolerance test.

Biologically active chromium supplements, such as high chromium yeast, will decrease blood sugar of people with elevated glucose values (hyperglycemic) and increase that of those with low blood sugar (hypoglycemic). ESSENTIAL TRACE ELEMENT IN LIPID METABOLISM

Improvements in overall lipid metabolism, like those for glucose and insulin variables, are dependent upon the amount of supplemental chromium. Suboptimal chromium intake is associated with signs and symptoms of chromium deficiency that are similar to those for cardiovascular diseases.

Total cholesterol, low density lipoprotein (LDL)- and high density lipoprotein (HDL) -cholesterol, total cholesterolIHDL ratio, and triglycerides have all been shown to improve in humans as well as animals following chromium supplementation.

Chromium supplementation of elderly subjects causes significant decreases in total cholesterol with larger decreases in subjects with the highest levels prior to supplementation.

Chromium supplementation in test group of men led to significant decreases in serum triglycerides and increases in HDL-cholesterol compared to placebo-treated subjects.

Chromium supplementation of patients being treated for diabetes led to significant improvements in diabetic symptoms and also increases in HDL-cholesterol.

Chromium may also help control hypertension. One study has shown prevention of sugar-induced hypertension in spontaneously hypertensive rats.

Daily supplementation of chromium substantially increases HDL cholesterol, which is considered one of the best indicators of risk of heart diseases.

The body contains about 9 mg of molybdenum. Present in all tissues, it is found mainly in the liver, kidneys, adrenal glands, bones, and skin. It is important to several enzyme systems, most significantly that of xanthine oxidase, which supports many functions, including uric acid metabolism and mobilization of iron from the liver for body use. Molybdenum is fairly easily absorbed in the gastrointestinal tract, though it competes with copper at absorption sites. It is eliminated through the urine and the bile.


Molybdenum is a vital part of three important enzyme systems, xanthine oxidase, aldehyde oxidase, and sulfite oxidase.It has a vital role in uric acid formation and iron utilization, in carbohydrate metabolism, and sulfite detoxification. In the soil and possibly in the body, as the enzyme nitrate reductase, molybdenum can reduce the production or counteract the actions of nitrosamines, known cancer-causing chemicals, especially in the colon. Found more in molybdenum-deficient soils, nitrosamines have been associated with high rates of esophageal cancer.

Xanthine oxidase (XO) helps in the production of uric acid, an end product of protein (purine) metabolism. Though an excess of uric acid is known to cause gout, recent studies show that, in proper concentrations in the blood, it has antioxidant properties and helps protect the cells and tissues from irritation and damage caused by single oxygens and hydroxyl free radicals. Thus, uric acid has a new image as being an important part of balanced human function and not just a waste product. Xanthine oxidase may also help in the mobilization of iron from liver reserves.

Aldehyde oxidase helps in the oxidation of carbohydrates and other aldehydes, including acetaldehyde produced from ethyl alcohol.

Sulfite oxidase helps to detoxify sulfurs in the body, particularly sulfites, which are used to preserve food. These potentially toxic and harmful substances can cause nausea or diarrhea and precipitate asthma attacks in sensitive individuals.


• RDA Recommendations (USA, 1989]

• 75-250 mcg/day for adults

•50-150 mcg/day for children (7-10 years)

15-40 mcg/day for infants

• The amount provided by the average diet ranges from 50-500 mcg/day.

• A safe and sensible amount of added molybdenum is from 150-500 mcg/day for adults and 50-300 mcg/day for children.

Further research is required, but it appears that molybdenum is very important for optimum health and longevity.

Deficiency and Toxicity

Molybdenum, like most trace minerals, is required in a specific narrow range of daily intake; amounts much greater than this may be toxic. Animals given large amounts experience weight loss, slow growth, anemia, or diarrhea, though these effects may be more the result of low levels of copper, a mineral with which molybdenum competes.

Information about molybdenum deficiency is limited. Low soil levels of molybdenum lead to increased levels of nitrates and nitrosamines, which increase the risk of cancer, especially in the esophagus and stomach.

Depletions or deficiencies of molybdenum are common, and its availability in foods is decreased through soil depletion and food processing. This mineral has come to the nutritional forefront in the last decade with the recognition of its essential nature and the concern about deficiency.


The food levels of molybdenum depend largely on soil content. Whole grains, particularly the germ, usually have substantial amounts; oats, buckwheat, and wheat germ are some examples of grains containing molybdenum. Many vegetables and legumes are also good sources. Brewer*s yeast, liver and organ meats are often fairly high in molybdenum.

As the use of nutritional supplements increase, there is a growing consumer demand for more sophisticated information on the products they are consuming. Some of the questions on Zinc Yeast concern the importance of zinc in the diet, the bio-availability of organic Zinc Yeast versus inorganic sources and toxicity issues. Zinc enriched yeast is the natural convenient, safe and economical way to increase zinc intake.


There is considerable evidence that zinc deficiency in humans is a serious worldwide problem as a result of soil losses and losses in food processing, this deficiency or depletion can produce a variety of symptoms. Zinc is involved in a multitude of human body functions and is part of many enzyme systems. Zinc is important in normal growth and development, the maintenance of body tissues, sexual function, the immune system, and detoxification of chemicals and metabolic irritants.

Essential partof more than 200 enzymes involved in digestion and metabolism

With regards to metabolism, zinc is part of alcohol dehydrogenase, which helps the liver detoxify alcohols, including ethanol, methanol, ethylene glycol and retinol (Vitamin A). Zinc is needed for lactate and malate dehydrogenase, both important in energy production. Zinc in carboxypeptidase (a digestive enzyme) helps in protein digestion.

Critical Immune Response

Zinc is used in a variety of immune responses. It is one of the supportive nutrients used to treat lowered immunity. Zinc has been shown to increase T lymphocyte production and enhance other white blood cell functions.

Zinc is effective in treating skin problems, and may have an anti-inflammatory function.

Zinc is one of the micro-nutrients used to treat skin problems such as boils, bedsores, general dermatitis and acne. Psoriasis is even occasionally responsive to zinc supplementation. Zinc may have an anti-inflammatory function, especially in the joints and artery linings.

Wound Healing Effect of Zinc

Zinc is used commonly to enhance wound healing. Taken before surgery, zinc has been shown in numerous studies to speed recovery time and reduce the incidence of postoperative complications, such as wound infections.

Zinc & Chromium are known to be important trace elements in diabetes as a cofactor for insulin.

Zinc is important to normal insulin activity. It is a required element for the normal exocrine and endocrine function of the pancreas.

Zinc effects on cadmium toxicity

Zinc therapy can reduce cadmium toxicity from pollution or from cadmium in water or foods. Cadmium toxicity may aggravate hypertension, atherosclerosis, and heart disease and produce complications of hypertension or stroke.


Zinc is fairly non toxic, especially in amounts of less than 100-150 mg of elemental zinc daily. The Recommended Dietary Allowance (RDA) for zinc in adults is 15 mg with additional amounts needed during pregnancy and lactation (up to 25 mg). With infections, burns, before or after surgery, in pregnancy, or with aging, 50-75 mg of zinc per day is suggested as a therapeutic dose. Groups at risk, such as growing children, pregnant women and elderly people should have a higher zinc intake provided by dietary measures or supplementation.

Recommended Dietary Allowances for Zinc

Under 1 year 3-5 mg

1-10 years 10 mg

11 years and older 15 mg

Pregnant Women 20-25 mg

Lactating women 25-30 mg

Food Grade Yeasts (of Saccharomyces cerevisiae) are widely used in Beer and Wine Brewing, baking of foods such as bread and cookies and in feeding of humans and animals. It is very important to emphasize that yeasts are able to naturally metabolize inorganic minerals into organic forms, similar to what plants do. Plants do the conversion for us taking the minerals from the soil. Mineral enriched yeasts do this by taking the minerals from enriched molasses providing one of the best natural food forms of minerals human can consume. Furthermore, yeasts have an excellent storage mechanism for B-vitamins , as do other organisms, for factors needed for growth and life. Yeast is a naturally rich source of proteins, minerals and B-complex vitamins. Not only does mineral enriched yeast offer a natural form of mineral, it also provides other nutrients when consumed.
