What is L-Arginine?
L-Arginine is an amino acid the body uses through the nitric oxide synthase pathway to produce nitric oxide, the signaling molecule that helps blood vessels relax and widen.
Why is bioavailability a consideration?
Bioavailability is the central consideration with oral L-Arginine supplementation — a significant portion is broken down by arginase enzymes before it can be converted to nitric oxide. This is why many formulas, including MaxVitalize, combine L-Arginine with L-Citrulline, which has a more reliable pathway to raising plasma arginine levels.
What does the research say?
Research has studied L-Arginine for its relationship with vascular tone and physical performance across numerous trials, establishing the scientific basis for its role in nitric oxide production.
L-Arginine's role in MaxVitalize
L-Arginine provides the direct substrate for nitric oxide production, working alongside Beet Root and L-Citrulline in a complementary three-ingredient stack. See the full ingredient list.
Safety considerations
L-Arginine is generally well tolerated. Consult a doctor if you have low blood pressure or take medication for blood pressure, since L-Arginine may have additive effects.
