L-Leucine Powder - an essential amino acid that is popular among strength and endurance athletes

L-Leucine Powder is an essential amino acid in the form of a soluble powder. Together with isoleucine and valine, it is one of the branched chain amino acids or BCAAs. It is most commonly found in the supplementation plan of strength athletes, bodybuilders, crossfitters, endurance athletes and other active people.

 

It takes the form of a highly soluble powder, which you just need to mix in water, juice or other beverage and drink. It is also great in a post-workout drink, which enhances its benefits. Thanks to its purely plant-based composition, it is suitable for vegans.

 

Other benefits of leucine include that it is a known precursor of the signaling protein mTOR. Therefore, leucine has the greatest potential of all amino acids. Strength athletes, bodybuilders, crossfitters, endurance athletes and other active people can benefit from these properties.

    Good product. It works as it should; the taste is natural, so that is to be expected.

    I only drink unflavored plant proteins mixed with water, and I have grown quite accustomed to their taste. Some of them even taste pleasant. However, leucine is punishing! When dissolved only in water, it tastes like expired cleaning agent mixed with thinner. Even when mixed with apple juice, a aftertaste remains, though it is much more tolerable. I am withholding one star because I am glad this packaging size is available.
