Threonine
Essential for collagen, gut lining and immunity.
What is Threonine?
Threonine is an essential amino acid important for making collagen and elastin, the proteins that give skin and connective tissue strength and stretch. It is also concentrated in the mucus that protects the gut lining and in antibodies, and it helps the liver process fat.
Health benefits of Threonine
- Helps build collagen and elastin for skin and tissue
- Supports the protective mucus layer of the digestive tract
- Contributes to antibody production and immune defense
- Aids fat metabolism in the liver
