L-Arginine 500mg 250 Caps, NOW Foods

L-Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion as well as DNA synthesis.

What is the source of NOW L-Arginine?

L-Arginine, like all NOW amino acids, is a synthetic substance produced in a laboratory. Because it is not derived from an animal source, it is considered a vegetarian product.

Naturally occurring amino acids are typically derived from animal sources, but this process is not hypoallergenic as animal proteins can be carried over. Also, it is more difficult to guarantee hormone- or pesticide-free products. Synthetic amino acids are well-tested, safe, and hypoallergenic.
