Magnesium (from whey mineral complex, rice bran, rice fiber and organic vegetable powder)

Magnesium is a mineral necessary for human life. Magnesium is essential to all living cells, but nearly 50% is found within the bones, where it plays a major role in bone and mineral homeostasis. Magnesium is also important for many cellular reactions, such as energy generation, cell membrane stabilization and protein activation. Food sources of magnesium include green leafy vegetables, nuts, meat, starches and milk1,2. The U.S. Food and Drug Administration (FDA) has established a Reference Daily Intake (RDI) of 400 mg magnesium for adults and children 4 or more years of age. RDIs, which are a set of dietary references for essential vitamins and minerals that are considered amounts sufficient to meet the daily requirements of healthy individuals, serve as the basis for calculating the percent daily value (%DV) amounts found on dietary supplement and food labels. Supplementation with magnesium is appropriate for many, as more than half of the U.S. population consumes less than 245 mg/day. When ingested as a naturally occurring substance in foods, magnesium has not been demonstrated to exert any adverse effects. However, mild gastrointestinal disturbances have been observed with excess magnesium intake from nonfood sources 2.

Whey mineral complex is a concentrated source of calcium and other minerals obtained from filtering whey. Besides calcium, it includes essential minerals such as phosphorus, magnesium, potassium, sodium and iron. It can be used as an additive for various foods such as drinks for the purpose of providing nutrition. The U.S. Food and Drug Administration (FDA) has been notified that industry considers whey mineral concentrate to be generally recognized as safe (GRAS) for its intended use and has not objected to its use for this purpose (GRN No. 52).

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 2. Rice bran also contains beta-sitosterol and other phytosterols, along with the essential omega-3 fatty acid alpha-linolenic acid (ALA) 3.

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.
