Your energy, your blood flow, your heart health. One molecule controls all three.

Nitric Oxide declines with age — and that decline accelerates during menopause — affecting blood flow, energy, and heart function in ways most wellness routines never address. Berkeley Life Nitric Oxide Support is clinically studied to restore it.

The 3 p.m. Energy Crash Ends Here.

Estrogen activates the enzyme responsible for Nitric Oxide synthesis. As estrogen declines, so does NO and with it, the blood flow that governs energy, cognitive clarity, and heart health. This isn't a hormone story.
It's a vascular one.

"After a few weeks on an NO supplement, that 3 p.m. slump disappeared. My focus returned, and I could finally finish my to-do list."

"This will be absolutely transformative for the millions of women who are currently suffering through this transition with limited solutions, outside of HRT."

DR. MARIZA SYNDER

“Berkeley Life is a company that has gained my respect for their commitment to the development of science-based products that modulate Nitric Oxide status and function. Their commitment to scientific rigor and innovative solutions makes them a powerful ally in the pursuit of functional health.”

Dr. Jeffrey Bland

“Blood flow and healing are critical to the success of our treatments, and the integration of Nitric Oxide has really helped. We continue to promote Berkeley’s N.O. for all of our body procedures as well as men presenting to our men's clinic – our patients are loving the results.”

Dr. Richard Moore

This Isn't a Supplement Just for How You Feel Right Now. It's a Foundation for What's to Come.

You're already doing the work. Eating well. Moving. Prioritizing sleep. And yet something has shifted — in your energy, your clarity, your heart health — in ways that don't respond to the things that used to work.  That shift has a biological explanation. During perimenopause, estrogen decline reduces your body's ability to produce Nitric Oxide. And Nitric Oxide governs the vascular function that underlies nearly everything you're trying to protect.  Berkeley Life Nitric Oxide Support is clinically studied to restore healthy NO production — the pathway perimenopause puts under pressure. And the test strips let you measure your levels before you start and again in 90 minutes, so you don't have to take anyone's word for it. You see it - then you feel it.

Estrogen decline reduces N.O. — the molecule your blood vessels need to stay flexible and open. Berkeley Life supports healthy blood pressure and arterial function as cardiovascular risk starts to rise.* 

12.5 pts avg. reduction in systolic blood pressure in the clinical trial.*

N.O. governs how efficiently your cells receive oxygen. When it declines, energy declines with it. Berkeley Life restores that system.*

300% increase in capacity to produce energy after 3 months.*

Cerebral blood flow depends directly on N.O. When it drops, so does mental sharpness. Berkeley Life supports the vascular foundation your brain runs on.* 

28% improvement in circulation — the gold standard measure of blood flow.*

Oxygen delivery to muscle tissue is a N.O. function. When it declines, recovery slows. Berkeley Life supports faster recovery and sustained endurance.*  

300% increase in capacity to produce energy after 3 months in a published clinical trial.*

Your Wearable Can't Track This, But This Test Strip Can

Berkeley Life Nitric Oxide Test Strips give you a real baseline — the same measurement method used in clinical research — in 10 seconds at home.
No lab. No appointment. No guesswork. Check your baseline before you start. Check again in 90 minutes.  Your wearable tracks your steps, your sleep, your heart rate. But Nitric Oxide?
That's been a blind spot. Until now.
Set your baseline today.
Most people see a sustained measurable difference within a month.*

Are Your Nitric Oxide Levels
 Holding You Back?

NO naturally declines with age — by 50% by age 40, and continues dropping every decade. This invisible drop affects energy, heart health, and how every organ in your body performs.

At 40, NO levels plummet, driving weight gain, mood swings, and poor sleep during perimenopause.
