Health Supplement

Three of the most important amino acids in the body are leucine, isoleucine and valine, collectively known as branched-chained amino acids (BCAAs). They are most important in maintaining muscle tissues, preserving muscle glycogen stores and preventing muscle breakdown during strenuous exercise. Many people have taken BCAA supplements to enhance physical training effects and improve performance during exercise.

BCAA’s inhibit protein breakdown under this condition. BCAAs are of particular interest to bodybuilders because unlike other amino acids, which are broken down in the liver, they are metabolized in the muscles. Here, they can be used to produce energy or construct new proteins. BCAA supplementation decreases nitrogen losses when compared with non-essential amino acids.

BCAA supplementation is combatting immunosuppression caused by prolonged exercise. Supplementation of BCAA’s to competing triathletes and runners increases plasma glutamine concentratiom which can decrease the incidence of upper respiratory tract infections in endurance athletes.
