How it works

More nitric oxide, better flow.

Nitric oxide is the molecule that relaxes and widens your blood vessels. Your body makes it from the amino acids L-citrulline and L-arginine, which is exactly what this 800mg blend delivers.

01

Supply

800mg of L-citrulline and L-arginine give your body the raw material it uses to make nitric oxide.*

02

Convert

L-citrulline is converted to L-arginine, then to nitric oxide, the signal your blood vessels respond to.*

03

Flow

More nitric oxide supports vasodilation, so blood, oxygen, and nutrients move more freely.*

What's inside

Three actives. One job: nitric oxide.

An 800mg blend of L-citrulline and two forms of L-arginine, the amino acids behind nitric oxide. No fillers you don't need.

Read the label first

Not all nitric oxide formulas are dosed the same.

Many nitric oxide supplements hide doses in a proprietary blend or lean on arginine alone. Here is how ours is built.

Questions

What to know before you start.

For pumps, take 2 capsules 30-60 minutes before training. For circulation support, take 2 capsules a day at a consistent time, with water.
Nitric oxide helps relax and widen blood vessels, which supports circulation and the delivery of oxygen and nutrients to your muscles.*
Both. L-citrulline is the precursor your body converts to arginine, then to nitric oxide, and arginine is the direct substrate. We include both, an 800mg blend.
No. There is no caffeine or stimulant. It is a clean amino acid blend you can take pre-workout or any time of day.
Yes. Beetroot adds dietary nitrates, a different path to nitric oxide, so the two complement each other well as a daily stack.
