The BCAA's are among the nine essential amino acids for humans, because our body can’t manufacture them. Their only source is our daily food or food supplementation. On the other hand, they account for 35% of the essential amino acids in muscle proteins. Leucine, Isoleucine and Valine are indispensable amino acids provided by mixed dietary protein intakes from different sources. BCAA's can also be consumed as food supplements, especially suggested around intense workouts or physical work. Our BCAA 6400 formula contains a 2:1:1 ratio of Leucine, Isoleucine and Valine.DirectionsTake 1-3 servings a day, before and after training, and at any other time like before going to bed.
