Following the principle of "more is more," many BCAAs available on the market use a ratio of 4:1:1 or even 8:1:1. This concept does not always work. For BCAAs to have the best possible effect, the ratio of components is crucial. On a daily basis, the body needs twice as much leucine as it does isoleucine and valine. The body can only get the most out of the individual components during and after training if they are provided in the right amounts. Studies show that the amino acids leucine, isoleucine and valine provide the body with the greatest benefits when combined in a 2:1:1 ratio.
