Alanine is a non-essential amino acid that is used to make proteins. It is used to break down tryptophan and vitamin B6.
It is an important source of energy for muscles and central nervous system, strengthens the immune system, and helps in the metabolism of sugars and organic acids.
Excellent sources of alanine include meat and poultry, fish, eggs, and dairy products. Some protein-rich plant foods also supply alanine.
