Leucine is one of the nine essential amino acids and can only be obtained from diet. Studies suggest that the amino acid leucine, in conjunction with adequate dietary protein, may help to build and maintain lean tissue and optimize body composition.* Active individuals and athletes may want to supplement with leucine pre-workout, intra-workout, and post-workout. NOW® Sports Leucine Powder is instantized for easy mixing in water, beverages, or smoothies – no clumping.
