Loved by Thousands of Customers

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.

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

    Haven't Noticed

    I am so sad to say this, but I really have not noticed any shift in energy levels at all. And actually, I took a very long nap yesterday so it seems even lower energy level. I haven't tested in the past couple days, but my first test strip barely showed any color AT ALL, so perhaps it will take longer to catch up in my system since it was soooo very low. I am still hopeful!

    We’re sorry to hear you haven’t noticed a change in your energy levels yet, but we really appreciate your honesty and the time you’ve taken to track your progress. It’s also great to hear you’re staying hopeful.

    Since you’ve only been using the product for about a week, it’s still very early in the process. Many people typically begin to notice changes after 4–6 weeks of consistent use, and in some cases it can take up to 12 weeks for more significant results, depending on individual baseline levels and consistency.

    For the most accurate tracking, we recommend testing your nitric oxide levels just before taking your capsules and then again about 90 minutes afterward. This can help you better see how your body is responding over time.

    If you experience any adverse effects or have concerns about how you’re feeling, we do recommend checking in with your healthcare provider to determine whether the product is the right fit for you.

    We’d really love to hear how things are going for you after a few more weeks of consistent use!

    Quality change

    With the new packaging, capsules are only partially filled.

    Thank you for bringing this to our attention, Scott.

    We understand why seeing capsules that appear only partially filled could be concerning, especially with the updated packaging. This can sometimes occur due to normal settling of the powder during shipping or slight variations in how the ingredients compact within the capsule. Please rest assured that each capsule still contains the full, measured amount of active ingredients as listed on the label, and the effectiveness of the product is not affected by how full the capsule appears.

    That said, we do take feedback like this seriously and would really like the opportunity to evaluate what you’re seeing more closely. If you’re able, please send photos to Help@berkeleylife.com so our team can review and assist further.

    We appreciate you taking the time to share your experience with us, and we’re here to help with any additional questions you may have.
