Alpha-alanine is a non-essential amino acid. Non-essential amino acids can be made by the body, so they don't have to be provided by food. Amino acids are the building blocks of proteins.

You may see the terms “L-alpha-alanine” and “D-alpha-alanine.“ The “L” refers to the “left-handed” chemical form of the alpha-alanine molecule. The “D” refers to the “right-handed” chemical form of the molecule. The L and D forms are mirror-images of each other.

Alpha-alanine is used for low blood sugar (hypoglycemia), diarrhea-related dehydration, liver disease, enlarged prostate (benign prostatic hypertrophy, BPH), fatigue, stress, and certain inherited disorders including glycogen storage disease and urea cycle disorders.

How it works

Alpha-alanine is an amino acid. It can affect blood sugar levels.


Possibly Effective
Low blood sugar (hypoglycemia) in people with type 1 diabetes

Some research shows that taking L-alpha-alanine by mouth can raise blood sugar levels after a “blood sugar low” due to taking too much insulin. L-alpha-alanine can also prevent blood sugar from dropping too low overnight.


Alpha-alanine seems to be safe when used appropriately for a short time. Side effects have not been reported in studies of alpha-alanine.



Pregnancy and breast-feeding: Not enough is known about the use of alpha-alanine duringpregnancyandbreast-feeding. Stay on the safe side and avoid use.Dosing considerations for Alpha-alanine.

Diabetes: L-alpha-alanine can increase blood sugar levels in people with diabetes. This can be helpful if blood sugar levels are too low, but it can be harmful if blood sugar levels are normal or too high. Monitor your blood sugar carefully if you have diabetes and use alpha-alanine.
