Threonine is an essential amino acid, meaning it must be obtained through diet as the body cannot synthesize it. It plays a critical role in protein synthesis, immune function, and the maintenance of connective tissues such as collagen and elastin.
For active individuals, threonine is important for muscle repair and growth, especially when combined with other essential amino acids. It also contributes to gut health by supporting the production of mucus and structural proteins in the intestinal lining.
Due to its involvement in tissue repair and immune modulation, threonine supplementation may support recovery after intense training and help prevent performance decline during heavy training cycles.
Synonyms:
L-threonine
Benefits:
- Aids in muscle protein synthesis
- Supports immune and gut health
- Promotes recovery from physical exertion
- Contributes to collagen and elastin production
Sources:
Found in meat, eggs, dairy, legumes, and protein supplements.
Observations:
Often included in EAA and BCAA formulas. Safe when taken in appropriate amounts; excessive intake may lead to imbalances with other amino acids.
