L-Arginine and Vitamin C
Vitamin C protects nitric oxide from oxidative breakdown, extending the vasodilatory effect of arginine.
L-Arginine
The nitric oxide precursor for blood flow and cardiovascular health.
Vitamin C
Antioxidant vitamin and iron-absorption amplifier.
Great to combine
These two are frequently stacked together; they complement each other and are commonly taken at the same time.

Frequently asked
Can you take L-Arginine and Vitamin C together?
Yes, they are commonly taken together. Vitamin C protects nitric oxide from oxidative breakdown, extending the vasodilatory effect of arginine.
What's the best time to take L-Arginine and Vitamin C?
Around the same time works well. L-Arginine: 30–60 minutes before exercise for performance; spread throughout the day for cardiovascular goals. Vitamin C: With iron-rich meals to maximize iron uptake.
How do L-Arginine and Vitamin C interact?
Synergy: Work better together than alone. Vitamin C protects nitric oxide from oxidative breakdown, extending the vasodilatory effect of arginine.
Related pairings
L-Arginine + L-Citrulline
L-Citrulline converts to arginine in the kidneys far more efficiently than oral arginine; the two share the same nitric oxide pathway.
L-Arginine + Magnesium
Magnesium supports vascular smooth muscle relaxation alongside nitric oxide from arginine.
L-Arginine + Zinc
Zinc is a cofactor for nitric oxide synthase, the enzyme that converts arginine to NO.
Collagen + Vitamin C
Vitamin C is a required cofactor for the enzymes that build collagen, so adequate vitamin C supports both dietary collagen and the body's own production.
