Nitric Oxide Support
The only Nitric Oxide supplement you can test and track with simple at-home saliva strips. Supports healthy blood flow, energy, heart health, and cognition daily.
One Molecule. Five Systems.
Two capsules a day. Clinically validated Nitric Oxide support for the systems that drive how you feel, perform, and age.
Potassium Nitrate
Vitamin C
Vitamin B12
Fermented Beet Root
Beetroot Extract (25% Betaine Nitrate)
Berkeley Life works via the dietary nitrate → nitrite → nitric oxide pathway, validated in double-blind, placebo-controlled trials. Nitric oxide signals blood vessels to relax and widen, improving circulation and supporting healthy blood pressure. Clinical research on Berkeley Life's formula showed reductions in carotid artery stiffness and improvements in vascular responsiveness after 8–12 weeks of daily use. Magnesium reinforces this by further relaxing smooth muscle in blood vessel walls.

Fermented Beet Root
Beetroot Extract (25% Betaine Nitrate)
Nitric oxide improves how efficiently your muscles receive and use oxygen — Berkeley Life's clinical trial subjects showed a 300% increase in capacity to produce energy after 3 months. Vitamin B12 and Thiamin (B1) are essential co-factors in cellular energy metabolism, and Magnesium plays a direct role in ATP production. The result is sustained stamina and reduced fatigue — with no stimulants.

Fermented Beet Root
Beetroot Extract (25% Betaine Nitrate)
The brain consumes ~20% of the body's blood supply. By driving vasodilation via the nitrate-to-NO pathway, Berkeley Life supports the cerebral circulation needed for sharp thinking and sustained focus. Vitamin B12 is critical for neurological function, nerve sheath integrity, and neurotransmitter synthesis. Thiamin (B1) supports glucose metabolism in the brain — the primary fuel for cognitive performance.

Beetroot Extract (25% Betaine Nitrate)
Nitric oxide is the key molecule behind blood flow to every part of the body — including sexual function. Berkeley Life's clinical pilot showed a 75% increase in libido and 83% enhanced orgasm after 60 days. Improved circulation supports desire and performance in both men and women. Vitamin C enhances NO bioavailability by reducing oxidative breakdown, extending the duration and magnitude of each dose.

Curious About Your Nitric Oxide Levels?
Our easy-to-use test strips help you monitor your body’s Nitric Oxide levels in seconds, so you can take control of your health.
Small Molecule. Big Impact.
Nitric Oxide (NO) helps signal your blood vessels to relax and expand, allowing oxygen and nutrients to move more efficiently throughout the body. It plays a key role in supporting energy, endurance, circulation, heart health, and sexual performance. But as we age, the body’s natural Nitric Oxide production begins to decline.
Berkeley Life is designed to help restore healthy Nitric Oxide levels, supporting blood flow, healthy blood pressure, daily energy, recovery, and overall performance so you can feel and function at your best every day.

Why Blood Flow Matters
Blood flow powers every part of your body, delivering oxygen and nutrients where they’re needed most. When circulation is strong, you feel the difference in your energy, endurance, focus, recovery, and overall performance. But as Nitric Oxide levels naturally decline with age, healthy circulation can slow down too.
Supporting blood flow helps your body perform at its best, promoting stamina, faster recovery, cardiovascular health, and long-term vitality.
Frequently Asked Questions
Berkeley Life is a practitioner-grade Nitric Oxide support company focused on vascular health, circulation, and healthy aging.
Our products are designed to support Nitric Oxide production — a critical molecule involved in blood flow, cardiovascular function, energy production, and cellular signaling.
Nitric Oxide is a signaling molecule produced in the body that helps:
- Relax and dilate blood vessels
- Regulate blood pressure
- Improve circulation
- Deliver oxygen and nutrients to tissues
- Support mitochondrial energy production
- Maintain endothelial function
Nitric Oxide production naturally declines with age.
Nitric Oxide declines due to:
- Reduced endothelial Nitric Oxide synthase (eNOS) activity
- Oxidative stress
- Chronic inflammation
- Insulin resistance
- Hormonal changes
- Poor oral microbiome health
By age 40–50, Nitric Oxide production may be significantly reduced compared to early adulthood.
Many Nitric Oxide supplements use L-arginine or L-citrulline.
Berkeley Life uses dietary nitrates, which:
- Bypass age-related decline in the arginine pathway
- Work independently of eNOS
- Have strong clinical validation
- Provide more consistent Nitric Oxide production
Our formulas are clinically studied and practitioner-trusted.
Berkeley Life uses food-grade potassium nitrate.
It is chemically identical to the nitrate naturally found in leafy green vegetables.
It is not the same as industrial-grade nitrates used in fertilizers or explosives.
Nitric Oxide is a natural signaling molecule essential for vascular health.
In conditions of extreme oxidative stress, reactive nitrogen species may form. Maintaining a healthy diet and lifestyle helps support balanced Nitric Oxide activity.
Dietary nitrates from vegetables and Berkeley Life formulas are considered safe for daily use in healthy adults.
