(原文)Optimum Nutrition's BCAA 5000 Powder provides a 5000 mg blend of the three Branched Chain Amino Acids (L-Valine, L-Leucine and L-Isoleucine) in every serving. The Branched Chain Amino Acids (BCAA's), so named because of their unique branched chemical structure, are essential in that the body cannot make them from other compounds. In recent times, these amino acids have been investigated研究 for their potential anticatabolic (preventing muscle breakdown) and anabolic (muscle building) effects.

Optimum Nutrition's BCAA 5000 Powder 裡每份含有5000 mg的 BCAA（L-Valine, L-Leucine and L-Isoleucine）。 BCAA之所以稱做支鍊氨基酸，是因為其獨特的化學結構，對我們的身體極有利用價值，且無法由其他複合物中獲得。在最近，這些氨基酸被研究證實是一種極具潛力的抗氧化劑（防止肌肉損失）並具有合成代謝的作用。
