You can also get BCAA's in cheap whey protein powder
Many athletes take branched chained amino acids (BCAAs) during their weight training workouts to enable them to increase their quality of their workouts and improve recovery ability, but research shows that BCAAs may also play a role in life extension. According to a study published in the October 6, 2010 issue of Cell Metabolism, BCAA supplementation increased the average life span of mice. It does this by stimulating the formation of new mitochondria, which is a structure in cells involved in energy production.
Indirectly, there are other ways that BCAA supplementation can prolong life. Individuals with chronic liver disease experience may improve insulin resistance with BCAA supplementation (International Journal of Molecular Medicine, July 2008) and cancer patients can enjoy a better quality of life as the BCAA leucine, in combination with a high protein diet and fish oil supplementation, has been shown to reduce the muscle tissue loss associated with cancer (British Journal of Cancer, March 2009). As that logical alien with pointy ears would say, “Use BCAAs to live long and have prosperous workouts!”
