As a supplement
Talk to your doctor or pharmacist.
Roll Call does not check drug interactions or assess personal safety.
A non-essential amino acid the body makes on its own and also gets from protein-containing foods. It plays a basic role in protein structure and in glucose metabolism.
Why it’s used
Included in some amino acid or protein-support supplements, though it is not commonly taken on its own for a specific effect the way its relative beta-alanine is.
What the evidence says
There is little dedicated clinical research on supplemental alanine (as distinct from beta-alanine) in humans, so no consistent effect from supplementation has been established.
