"I was a doubter! Waited 6 months before submitting this review because I wanted to make sure of the long term outcomes first. Now, six months later I know Nitric Oxide really has improved my health. My energy level is up and my overall feeling of well being is better. Highly recommend this product to anyone of any age. I’m 70 years old and it has made an improvement in my daily feeling of well being."

    This works !!

    I have been tracking my nitric oxide levels with test strips while experimenting with various supplements. While other brands resulted in only slight changes, Berkeley’s nitric oxide supplement produced a dramatic improvement in my readings.

    Very relevant. I have been able to cut back on blood pressure medications. It is one of the most underappreciated supplements.
