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.

Darrin E.

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

    Thank you for sharing your feedback, Richard. I appreciate you giving the sample pack a try and tracking your experience.

    Day 5 is still very early in the process, and it sounds like you're being realistic about what to expect from a short trial period. The 3-day sample pack is really designed to give you a feel for the product rather than deliver significant results, so your timeline aligns with what we'd typically expect.

    Most people need several weeks of consistent use to notice meaningful changes, so if you do decide to continue with a longer course, that would give you a better window for evaluating how the product works for you.

    You can always reach out to us at help@berkeleylife.com for more assistance or education.

    Thank you for taking the time to share your honest feedback, and we appreciate you giving us a try!

    Stomach Upset

    I tried it for two days, taking it with food; however, experienced stomach upset. Any suggestions?

    Thank you for sharing your experience, Anna. While Berkeley Life is generally well tolerated, everyone can respond differently to a dietary supplement.

    Our recommended serving is two capsules daily with water, preferably after a meal. If you experienced stomach upset taking both capsules together, you could try splitting the serving—one capsule in the morning and one in the evening—to see if that is better tolerated.

    If the stomach upset continues, we recommend discontinuing use and speaking with your healthcare provider before trying it again, particularly if you have any underlying medical conditions or take medications.

    Please let me know if you have any other questions or concerns!

    Nitric oxide

    I’ve been taking this product for six months now. If it has brought my energy levels back up where they should be I’m not fragile anymore or exhausted. Also cut me back on eating so much chocolate. And I can test myself daily with the strips on right up where I should be. I will never stop taking this product best product ever.
