What is pyruvate?
pyruvate is a derivative of pyruvate acid and plays a role in glycolysis or sugar metabolism. While the human body naturally synthesizes this compound of glucose, it also occurs naturally in red wine, dark beer, red apples and other foods. Pyruvate is also available as a food supplement. It is reportedly reduced to reduce cholesterol, improve endurance and performance during aerobic exercise and support weight loss. In fact, it is well known to bodybuilders, athletes and other sports nutrition industries.
The benefit for energy production from this nutrient is a mechanism called Krebs cycle. First, it is converted into acetyl-koenzym A, an event that triggers a number of biochemical reactions that begin with oxidation of glucose components to carbon dioxide during cellular breathing and lead to the production of adenosine triposphate (ATP) used for fuel cells. This process is also known as a cycle of citric acid, or by cyclus of tricarboxylic acid.
Even the process that pyruvates increases energy in the body seems to be clear, scientific evidence to support the claim that supplementation increases athletic endurance and the performance is impassable and in some cases contradictory. Several early experiments with athletes have shown that endurance and performance was increased, especially when this nutrient was combined with creatine. A 2005 study, including 23 previously untrained women who were introduced under the supervision of the exercise program, showed that supplementation in the form of calcium pyruvate did not affect the performance or composition of the body during training.
Premature studies conducted at the University of Pittsburgh Medical Center at the end of 90. For example, one study has shown that the supplementation pyruvatin has to regain weight and body fat in obese women who were re -introduced into a dietWith high calories after previously undergoing weight loss program. In addition, the supplement allowed weight loss while without sacrificing protein reserves and muscle mass. However, it should be noted that the supplement used in this study was a combination of pyruvate and dihydroxyacetone (DHA).
It is clear that further research is needed to justify some health claims about this nutrient. From studies that have so far been conducted, it also seems that better results are observed when this compound is used either with DHA or creatine. In addition, a standardized dose has not yet been determined. However, excessive doses can be caused by gastrointestinal irritation.
