Blood FlowIs Everything.

Nitric Oxide is the molecule your body makes to keep blood flowing freely. After 40 it starts to decline, taking heart health, energy and recovery with it. Read your strip and see where you are.

New Result in90 Minutes.

That's what two capsules do. The formula is built for daily use. Consistent Nitric Oxide support is what protects blood flow every day.

Your Level HeldSteady.

Nitric Oxide takes time to build for some people. The formula is designed for daily use, and consistency is what moves the reading.

Readings MoveDay to Day.

A single strip is a snapshot. Hydration, food and timing all shift it. Daily Nitric Oxide support is what builds a steady baseline.

Why Levels Drop.

The Foundation for What's to Come.

More Than Menopause.

The Foundation for What's to Come.

Nitric oxide production naturally declines with age, and stress, diet and life stages like menopause can speed that up. That's why testing, and supporting it daily, matters.

Estrogen supports the enzyme that makes Nitric Oxide in your blood vessels. As estrogen declines, Nitric Oxide production drops, affecting blood flow, vascular function and blood pressure. That's why testing, and replacing it, matters now.

By the age of 40, your nitric oxide levels have reduced by 50%

Three steps, one pathway.

Dietary nitrates from beetroot and leafy greens convert to Nitric Oxide, supporting vasodilation and circulation.

01
Plant-based nitrates

Dietary nitrates from beetroot and leafy greens. The same pathway your diet uses, delivered at a clinical dose.

02
Converts to nitric oxide

Oral bacteria and the body convert nitrate to nitrite to Nitric Oxide. This route doesn't depend on the enzyme that fades with age.

03
Supports vasodilation & circulation

Vessels relax, blood moves, and the systems that depend on it (heart, brain, muscle) get what they need.

More Than a SupplementThe Foundation for How You Age

Nitric Oxide keeps blood vessels flexible and blood flowing. Production naturally declines with age, and life stages like menopause can speed that up. Daily support helps maintain healthy circulation and blood pressure already within normal range.* Test your levels, then support them.
