L-Methionine is an essential sulfur-containing amino acid and the initiator of all protein synthesis (start codon). It is the precursor to SAM-e (S-adenosylmethionine), the universal methyl donor, and cysteine/glutathione via the transsulfuration pathway. Critical for methylation, detoxification, and antioxidant defense.

L-Leucine is the most anabolic of the three BCAAs and the primary activator of the mTOR (mammalian target of rapamycin) pathway for muscle protein synthesis. The "leucine threshold" concept (2.5-3g per meal) is central to modern sports nutrition for optimizing muscle growth and preventing sarcopenia.
