Alanine

Other Name(s):

a-alanine, a-amino-propionic acid, b-alanine, b-amino-propionic acid

Unsubstantiated Claims:

Alanine may be beneficial in treating diabetes because it aids glucose metabolism and helps prevent hypoglycemia (a deficiency of sugar in the blood).

Recommended Intake:

Amino acids (AAs) are available as individual AAs or in proprietary AA combinations, as well as part of multivitamin formulas, proteins and food supplements. The forms include tablets, fluids and powders. Adequate protein in the diet, however, should provide a sufficient source of all amino acids.

There are no conditions that increase the requirements for alanine.

Side Effects, Toxicity and Interactions:

The use of a single amino acid supplement may lead to negative nitrogen balance, decreasing the metabolic efficiency and increasing the workload of the kidneys. In children, taking single amino acid supplements may also harmfully affect growth parameters.

Always avoid taking individual amino acids in high dosages for prolonged periods of time.

Women who are pregnant or breast-feeding should not use alanine supplements.

Additional Information:

Alanine has a formula of C₃H₇NO₂ and a molecular weight of 89.09.
