L-Leucine is one of the essential amino acids and also belongs to the BCAA group. The 9 essential amino acids the body cannot synthesize and must be supplied by the diet, including sport supplements.
In modern BCAA products Leucine is found in larger and larger ratios, so why not take pure Leucine, which allows proper and precise dosing? You can even take it alongside protein shakes.
Take 1 serving before and after training, and 1 serving between each meal.
