Recommended intake

Alanine is an amino acid that is used to make proteins. It is used to break down tryptophan and vitamin B6. It is a source of energy for muscles and the central nervous system. It strengthens the immune system. And it helps the body use sugars. Amino acids (AAs) are available as single AAs or in AA combinations. They’re in multivitamin formulas, proteins, and food supplements. The forms they come in include tablets, fluids, and powders. 

If you eat enough protein in your diet, you should be getting all amino acids.

There are no conditions that increase the need for alanine.

Side effects, toxicity, and interactions

Using a single amino acid supplement may lead to negative nitrogen balance. This can lessen how well your metabolism works. It can make your kidneys work harder. In children, single amino acid supplements may cause growth problems.

You should not take high doses of individual amino acids for long periods of time.

Women who are pregnant or breastfeeding should not use alanine supplements.
