Alanine is a nonessential amino acid--amino acids being the building blocks of proteins. This amino acid is nonessential because the body can produce it using other, essential, amino acids. Alanine is a very common and versatile amino acid.
Since this amino acid can be produced by modifying existing essential amino acids in the body, consumption of alanine is not technically required, but it is still strongly suggested, so as to allow the essential amino acids to fulfill their other purposes.
