Real people. Real results. See how Berkeley Life is helping customers feel more energized, balanced, and supported every day.

Excellent N.O. Booster

I've tried a few different N.O. boosters. Berkeley Life has proven to be the most effective and more importantly, the most consistently effective product. It seems their quality control is above the others and I'll continue to buy from them for both reasons.

Noticeable increased energy level

I have been taking the NO tabs daily. My energy level is up and moreover sustained.

Gail M.

Improved Health

I am 69 yrs. old, and I am taking NO for heart health, blood pressure, and gut health. I have been taking it for three weeks, and already I can see and feel a difference. I have been taking the liquid, but just purchased the gum to try. I look forward to continued physical and mental improvement. Thank you

    Sample pack

    I felt significant improvement in mood and energy levels after taking only 1 capsule daily for a week. Daily dose is two capsules. I have tried a lot of vitamins and various supplements, most without any noticeable change. This NO is different, it feels like it improves my heart health. For that reason, I am ordering more.

    It really works.

    I think you should try this stuff. Two things: 1.The day after I took NO foundation, I was air drumming in the car like I do and I noticed that my rings were spinning around my fingers because my blood pressure had noticeably dropped. 2.I have had Raynaud’s syndrome where my circulation in my hands and feet is so poor, they go completely white. That did not happen.. in the middle of 30ish degree weather, at that. And BONUS**:my digestion seemed to be better which is crazy because I deal with chronic gallbladder pain. Highly recommend you try.

    Thank you so much for sharing your incredible experience, Jaron! We're absolutely thrilled to hear how N.O. Foundation has made such a noticeable difference for you. It's amazing that you could feel the circulation benefits so clearly - from your rings fitting differently to experiencing relief from Raynaud's syndrome even in cold weather! That's exactly what our Nitric Oxide support is designed to promote. And what a wonderful bonus that your digestion improved too - better circulation can indeed support overall wellness in ways that might surprise us. We're so grateful you took the time to share these detailed results and highly recommend our Sample Pack to others. Thank you for being part of the Berkeley Life community!
