Calcium pyruvate may cause side effects including gas, bloating, stomach upset and diarrhea. These are more prevalent when the supplement is taken in large dosages.
Calcium pyruvate, often referred to as simply pyruvate, may be taken to treat obesity, cataracts, high cholesterol and cancer. It may also be used as a weight loss supplement or an athletic performance enhancer. Pyruvate is produced when sugar is broken down by the body. It's thought that pyruvate increases the breakdown of fat in the body.
Pyruvic acid, a liquid form of pyruvate, is applied to the skin to reduce signs of aging. When a 50 percent pyruvic acid skin peel is applied to the skin for four weeks, signs of aging, such as fine wrinkles and dark spots from sun exposure, are reduced, and the skin becomes smoother.
The exfoliation of the outer layers of the skin is thought to help diminish the signs of aging. Because the application of pyruvic acid can cause burns to the skin, it should only be done in a professional health care setting.
According to WebMD, there is insufficient evidence that pyruvate provides any benefits other than reducing wrinkles and other signs of aging. Based on research studies, its effectiveness for cancer, cataracts, weight control and performance enhancement is debatable.
