A non-essential amino acid is an amino acid that your body can create on its own. There are 11 non-essential amino acids: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.

L-glutamine is an essential amino acid and one of the building blocks of protein. When the body experiences a glutamine deficit, it can break down protein stores—like muscles—to get more of it.

Adding The Vitamin Shoppe^® brand L-Glutamine to your supplement stack can support protein synthesis and muscle recovery so you can keep flexing on your wellness goals.
