Calcium (from whey mineral complex, rice bran, rice fiber and organic fruit and vegetable powders)

Calcium is the most abundant mineral in the human body. Over 99% of total body calcium is found in the bones and teeth. The remaining 1% is found throughout the body in blood, muscle and the intracellular fluid. Calcium is used for muscle contraction, blood vessel constriction and relaxation, the secretion of hormones and enzymes, and nervous system signaling. A constant level of calcium is needed to be maintained in the body in order for these processes to function properly. The body gets the calcium it needs through food and by being extracted from bones. Calcium-rich foods include dairy products and dark, leafy greens. For dietary calcium, vitamin D is important and recommended for optimal calcium absorption through the intestine. Calcium extraction from bones occurs when dietary calcium is insufficient and can lead to weakened bone structure 1.

Many individuals in the U.S. consume inadequate amounts of calcium. The U.S. Food and Drug Administration (FDA) has established a Reference Daily Intake (RDI) of 1,000 mg calcium 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.

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 fruit and vegetable powders are obtained from organically grown fruits and vegetables, including strawberry, raspberry, blueberry, cherry, pomegranate, cranberry, broccoli, tomato, carrot, spinach and kale.
