L-Arginine and L-Citrulline for Men

Our verdict

L-Arginine and L-Citrulline for Men works out to $0.72 per serving of l-arginine, at 1000mg per serving in capsule form. That puts it above the median of the 24 l-arginine products we can price per dose, where the typical serving costs $0.11, a Value Index of 0.2 where the median product is 1.0. One container lasts 60 days at the label dose of 1 serving a day, about $21.50 a month. We could not verify a third-party certification for Havasu Nutrition in a public registry.
