Key differences

Option A

Methionine

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.

Categories

Common forms

  • L-Methionine · 90% bioavailability

Option B

Histidine

L-Histidine is an essential amino acid and precursor to histamine, carnosine, and hemoglobin. It is critical for immune response, gastric acid secretion, and metal ion chelation. Combined with beta-alanine, it forms carnosine in muscle tissue. Deficiency affects growth, immune function, and red blood cell production.

Common forms

  • L-Histidine · 92% bioavailability
