Faster recovery – superior results in resistance or endurance based exercise

Leucine, isoleucine, and valine comprise the branched-chain amino acids (BCAAs). Amino acids are the building blocks of muscle protein and are of critical importance to achieving training goals and recovery after training. BCAAs make up about one-third of all amino acids in muscle but are not produced within the body themselves, so must be obtained from the diet. However, during intense exercise, the body can break down BCAAs in order to provide energy to working muscles if the supply of carbohydrate is insufficient. In short, BCAAs are of vital importance in the athlete’s diet.

Why choose ISO BCAA®?

Leucine is essential when it comes to driving muscle growth. In fact, compared to all other amino acids, leucine by far outperforms these in its ability to stimulate muscle protein synthesis, a marker of muscle growth. Therefore, ISO BCAA® features a blend of 4:1:1 of leucine: isoleucine: valine. Consuming ISO BCAA® before, during and after workouts can provide the essential amino acids to support addaptations made from training. In fact, several studies have demonstrated the anabolic and anti-catabolic effects of amino acids taken before and after exercise, and may also improve recovery from intense exercise.
