Three months in and my endurance has changed
“Since starting Berkeley Life three months ago, my endurance has improved dramatically. I'm pushing past plateaus I couldn't break through for years.”
TEST IT. DON'T GUESS IT.
Know your Nitric Oxide level in 10 seconds.
Nitric Oxide helps your blood vessels relax and widen so oxygen and nutrients can move where they are needed. Your body makes less of it as you age. A saliva strip shows you where you stand, and a daily dietary nitrate capsule helps support healthy levels.

Nitric Oxide Support
The only Nitric Oxide supplement you can test and track with simple at-home saliva strips. Supports healthy blood flow, energy and cognition daily.
One Molecule. Five Systems.
Two capsules a day. Nitric Oxide support for the systems that shape how you feel, perform and age, with a test strip so you can see it working.
Potassium Nitrate
Vitamin C
Vitamin B12
Fermented Beet Root
Beetroot Extract (25% Betaine Nitrate)
Berkeley Life works through the dietary nitrate → nitrite → Nitric Oxide pathway, the same route your body uses after a plate of leafy greens. Nitric Oxide is the signal that tells the smooth muscle lining your blood vessels to relax and widen, so blood moves more freely to the tissues that need it. Magnesium supports that same relaxation response. This is the foundation the other four systems are built on.
Potassium Nitrate
Vitamin C
Vitamin B12
Fermented Beet Root
Beetroot Extract (25% Betaine Nitrate)
Better blood flow means more oxygen reaching muscle tissue, and more oxygen means your cells can turn fuel into energy more efficiently. Vitamin B12 and Thiamin (B1) are essential co-factors in cellular energy metabolism, and Magnesium plays a direct role in ATP production. Stimulant-free by design, so there is no caffeine, no crash and nothing to build a tolerance to.

The brain is one of the most blood-hungry organs you have, and it holds no reserve, so how it performs tracks what reaches it. By supporting vasodilation through the nitrate-to-NO pathway, Berkeley Life supports the cerebral blood flow behind sharp thinking and sustained focus. Vitamin B12 supports neurological function and nerve health, while Thiamin (B1) supports glucose metabolism in the brain, its primary fuel.

Nitric Oxide is not aimed at one organ. It is a signalling molecule made along the entire lining of your blood vessels, which is why people describe Nitric Oxide support as a whole-body difference rather than a single effect. Vitamin C helps limit the oxidative breakdown of NO, extending how long each dose stays available. Fermented beet root and beetroot extract supply nitrate in the form your body converts most readily.

Your body's ability to make Nitric Oxide drops off from roughly your thirties onward, and diet alone often does not keep pace. Berkeley Life supplies nitrate every day so production has something to work with. And because it is the only NO supplement that comes with its own saliva test strip, you are not taking it on faith. You can watch your own levels respond within days and adjust from there.
Complete Your System
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 is a signalling molecule your body produces on its own. It tells the smooth muscle in your blood vessels to relax, which lets them widen so oxygen and nutrients can reach tissue more easily.
Production falls as you get older. By your forties and fifties most people make meaningfully less than they did at twenty. Berkeley Life works through dietary nitrate, the same pathway your body uses with leafy greens and beetroot, rather than the arginine route that becomes less efficient with age.

A Smarter Approach ToNitric Oxide
Most Nitric Oxide products use L-arginine or L-citrulline, which rely on an enzyme route that becomes less efficient with age. Berkeley Life uses dietary nitrate, the same pathway your body uses with leafy greens, which works independently of that enzyme.

Frequently Asked Questions
It is a signalling molecule your body makes on its own. Its main job is telling the smooth muscle in your blood vessels to relax, which allows them to widen so oxygen and nutrients can reach tissue more easily. It is involved in energy production and normal vascular function.
Production falls with age. Most people make meaningfully less in their forties and fifties than they did at twenty. Diet plays a part too, since dietary nitrate comes largely from leafy greens and beetroot, and so does the health of the bacteria in your mouth, which do the first step of the conversion.
You touch a strip to your tongue for a couple of seconds and the pad changes colour within about fifteen seconds. You match it against the printed scale on the tube. It indicates salivary nitrite, a marker your body produces along the Nitric Oxide pathway.
The strips are for general wellness tracking. They are not a medical or diagnostic device and they do not diagnose anything.
Potassium nitrate, vitamin C, vitamin B12, fermented beet root and beetroot extract standardised to 25% betaine nitrate. The full panel is printed on every bottle. There is no proprietary blend, so you can see the dose of each ingredient.
Berkeley Life uses food-grade potassium nitrate. It is chemically identical to the nitrate that occurs naturally in leafy green vegetables, and it is not the same material as the industrial-grade nitrates used in fertiliser.
If you take prescription medication, are pregnant or nursing, or have a medical condition, speak with your healthcare provider before starting this or any supplement. Bring the bottle so they can see the full ingredient panel.
