Full Product Description

Applied Nutrition’s Leucine 4K provides 4000 mg of L-Leucine per six capsule serving, making it a concentrated source of this branched-chain amino acid (BCAA). L-Leucine plays a critical role in the initiation of muscle protein synthesis and is considered the most anabolic of the three BCAAs due to its regulatory role in mTOR signalling pathways [1]. As a essential amino acid, L-Leucine must be obtained from dietary intake or supplementation, particularly in those undergoing intense physical training [2]. The high dose per serving supports users aiming to maintain or build lean muscle mass through resistance training and sport.

This product is manufactured in the UK in a facility adhering to ISO 22000, BRC, GMP & Halal quality standards and is suitable for vegans and vegetarians.
