ISOLEUCINE ETHYL ESTER – esterified version of the amino acid isoleucine. Esterification is a process that significantly improves the effect of the supplement. Esterified amino acids show better bioavailability. Compared to the free form of isoleucine, the ethyl ester of this amino acid can be used in lower doses. It has a very strong anti-catabolic and pro-anabolic effect. Isoleucine ethyl ester can often be found in the most modern supplements, which are supposed to have a much better effect. ISOLEUCINE ETHYL ESTER is usually found in advanced BCAA formulas, but also pre-workout supplements.

Dosage: 3-5 g per serving.
