What It Actually Is
L-Arginine is an amino acid the body uses to produce nitric oxide, a molecule that helps blood vessels relax and widen.
What Research Generally Shows
The nitric oxide pathway is well-established biochemistry. Supplemental arginine's practical effect on blood flow and vitality varies by individual and dose — clinical doses in research are often several grams daily, well above what a single gummy blend typically provides.
The Honest Gap
VigorBoost's arginine amount isn't disclosed within the 82mg blend, and 82mg total (split among eight other ingredients) is far below gram-level research doses.
