You don’t need another coffee. You need energy that holds up through the 7am workout, the back-to-back meetings, and everything after.
Nitric oxide helps your muscles receive and use oxygen more efficiently. In Berkeley Life’s clinical study, participants showed a 300% increase in capacity to produce energy after 3 months.* Vitamin B12 supports normal energy metabolism, so you feel steady instead of wired.*
No caffeine. No jitters. No 3pm crash. Just sustained stamina and less fatigue, from a formula made to fit the life you’re already living.*

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.

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.

After age 40, the body's ability to produce Nitric Oxide declines significantly, reducing blood flow and increasing cardiovascular strain. Berkeley Life's Nitric Oxide Support helps replenish NO levels through the dietary nitrate pathway, supporting vascular flexibility, healthy blood pressure, and metabolic efficiency. Among the top Nitric Oxide supplements available today, Berkeley Life is one of the few backed by double-blind, placebo-controlled clinical trials. Vitamin C enhances NO bioavailability by reducing oxidative breakdown, extending the duration and magnitude of each dose.

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.
