Alpha-alanine (typically as L-alpha-alanine or D-alpha-alanine) is a non-essential amino acid. Non-essential amino acids can be made by the body.

Amino acids like alpha-alanine are the building blocks of proteins. Because alpha-alanine can be made by the body, it doesn't need to be consumed in food. Alpha-alanine can affect blood sugar levels.

People use alpha-alanine for dehydration from diarrhea, enlarged prostate, schizophrenia, stress, and many other purposes, but there is no good scientific evidence to support these uses.

Don't confuse alpha-alanine with the similarly named beta-alanine. These are not the same.
