L-Arginine

An amino acid found in protein foods such as meat, fish, dairy, nuts and seeds. The body also makes it, and uses it to make nitric oxide and other compounds. Our Arginine capsule carries 500 mg of L-arginine.

L-Arginine
Dose used in research Food supplies roughly 4 to 5 g a day. Studies commonly use 2 to 6 g a day, split into doses.

Cautions

Ask a doctor first if you take blood pressure medication, nitrates or erectile dysfunction medication: arginine can add to their effects.

Not advised after a recent heart attack.
