Nutricost L-Arginine L-Citrulline Complex 750mg, 240 Capsules - Non-GMO

Our verdict

Nutricost L-Arginine L-Citrulline Complex 750mg works out to $0.08 per serving of l-arginine, at 750mg per serving in capsule form. That puts it the cheapest quarter of the 24 l-arginine products we can price per dose, where the typical serving costs $0.11, a Value Index of 1.5 where the median product is 1.0. One container lasts 240 days at the label dose of 1 serving a day, about $2.37 a month. We could not verify a third-party certification for Nutricost in a public registry.
