Methionine is an essential amino acid involved in protein synthesis, detoxification, and methylation processes in the body. It plays a critical role in the formation of other amino acids like cysteine and compounds like glutathione, a powerful antioxidant.
In the context of fitness and supplementation, methionine supports muscle growth, tissue repair, and liver health. It’s also important for metabolic processes that affect performance and recovery.
Methionine’s role in glutathione synthesis may help protect muscles from oxidative stress during intense exercise, making it relevant for recovery and cellular protection.
Synonyms:
L-Methionine
Benefits:
- Supports protein synthesis and tissue repair
- Aids in liver detoxification
- Precursor to antioxidants (glutathione)
- Contributes to metabolic health and performance
Sources:
Found in eggs, fish, meat, and some nuts and seeds.
Observations:
Typically included in amino acid complexes or protein supplements. High doses may lead to imbalances if not balanced with other amino acids (like glycine). Excess intake may raise homocysteine levels if unsupported by B vitamins.
