What is l-arginine?

L-arginine is an amino acid that you can find naturally in foods like fish, meat and nuts. L-arginine is semi-essential (conditional), which means that your body can produce the amino acid, but you also need to include some sources of the amino acid in your diet.

What does the “l” in l-arginine stand for?

The letter L in front of arginine stands for “levorotatory,” which is a chemistry term that means the amino acid didn’t bond with a protein molecule (free form). This helps providers categorize amino acids based on how similar they are to the amino acids humans produce in their own bodies. The L designates that it easily absorbs into your body because it’s most similar to amino acids already in your body.
