Bodybuilders and athletes should consult their physician before opting for a dietary supplement which they think can help improve their performance. This NutriNeat article presents information on the possible side effects of calcium caseinate.
According to the National Health and Nutrition Examination Survey (NHANES) data collected from 2003 to 2006, that covered all types of dietary supplements, indicates that 53 % of American adults took at least one dietary supplement, most commonly multivitamin/multimineral supplements (taken by 39 % of all adults). Women were more likely than men to take dietary supplements.
Dietary supplement ‘calcium caseinate’ is a protein that is obtained from casein present in skim and milk. It contains about 17% glutamic acid―a proteinogenic amino acid. As you know, casein is the main protein present in milk. About 80% of protein in cow milk is casein. Athletes and bodybuilders consume protein supplements which help increase the rate of metabolism, promote fast burning of fat, and help build muscle. They consume calcium caseinate supplement before going to bed as it promotes a higher metabolic rate while sleeping and keeps the body in a muscle-building state all night long. It is also consumed as a snack before going to bed. It is taken with breakfast, or as a meal after working out.
Those who need a slow and sustained nutrient supply take this supplement instead of whey protein, because when ingested, whey protein breaks down at a relatively faster rate while this supplement keeps releasing amino acids into the blood stream for several hours. In the food industry, the compound calcium caseinate is added to powders that require a quick dispersion in water, for example, instant cream soups and coffee creamers. Thus, it is used as a food additive too.
Possible Side effects
Dr. Russell Blaylock M.D., has described in his book Excitotoxins: The Taste that Kills that calcium and sodium caseinates as food additives always contain free glutamate. The review of this book is available on the American Nutrition Association’s Nutrition Digest, Volume 36, No. 4. Although MSG is not added to the supplement as an ingredient, it is formed during processing, and therefore, it may not be mentioned on the label. To be on the safe side, pregnant and breastfeeding women and those who are about to undergo a surgery should avoid taking calcium caseinate supplement.
According to researchers, natural casein present in milk is the best protein for muscles, and the protein provided through this dietary supplement is actually of no use to muscles. Pure casein is known for its unique anabolic properties, and so, raw milk casein can keep your muscles in a sustained anabolic mode for an extended period of time. But the manufacturers of dietary supplements want you to believe that their product is the best one.
The U.S. Food and Drug Administration (FDA) regulates dietary supplements, but less strictly than the way it regulates prescription or over-the-counter drugs. Consumers should keep in mind that minimally processed foods and supplements are considered healthy, because they contain compounds that are close to their natural state.
