Zinc is an essential trace element necessary for the functioning of approximately 100 different enzymes in the body. It plays a vital role in many biological processes, such as the maintenance of protein structure, the regulation of gene expression and the metabolism of hormones. Zinc is abundant in red meats, certain seafood and whole grains, and many breakfast cereals are fortified with zinc. The proportion of dietary zinc absorbed is determined by the amount of zinc already present in the body, with higher absorption occurring when zinc status is low 1.
Zinc is regarded as relatively safe and generally well tolerated when taken at recommended doses. The U.S. Food and Drug Administration (FDA) has established a Reference Daily Intake (RDI) of 15 mg zinc for adults and children 4 or more years of age (21CFR101.9). RDIs are a set of dietary references for essential vitamins and minerals that are considered amounts sufficient to meet the daily requirements of healthy individuals. RDIs serve as the basis for calculating the percent daily value (%DV) amounts found on dietary supplement and food labels.
Mustard sprout. The greens and seeds of the Indian, or brown mustard plant, Brassica juncea, have been cultivated in Asia and Europe for thousands of years 2. Growing Indian mustard sprouts in mineral-enriched soil can increase the amount of minerals concentrated in the plant’s tissue. The sprouts can then be used in dietary supplements as sources of essential and trace minerals such as chromium, iron, manganese, selenium and zinc 3.
Rice bran is made from the bran layer, underneath the hull layer, of rice, Oryza sativa. Rice bran is high in dietary fiber, and is an excellent source of protein, vitamin E, thiamin, niacin, vitamin B6, pantothenic acid and a number of minerals, such as iron and magnesium. It is also a good source of folate and riboflavin 4. Rice bran also contains beta-sitosterol and other phytosterols, along with the essential omega-3 fatty acid alpha-linolenic acid (ALA) 5.
Rice fiber is the soluble and insoluble fiber obtained from the bran layer of the rice kernel.
Organic vegetable powders are obtained from organically grown vegetables, including broccoli, tomato, carrot, spinach and kale.
