Science
Called the ‘miracle molecule’, Nitric Oxide (NO) is well demonstrated to be instrumental in circulatory health — thanks to highly respected, peer-reviewed research. In fact, the Nobel Prize in Medicine was awarded to three American scientists in 1998 for their discoveries on ‘Nitric Oxide as a signaling molecule in the cardiovascular system’*.
As a key to healthy circulation — including vasodilation (relaxing of blood vessel walls), blood flow, blood pressure, and oxygen delivery — Nitric Oxide is deeply connected to almost every biological system in the body. Because of the wide-reaching benefits of adequate circulation, Nitric Oxide is closely linked to supporting healthy energy levels, cognitive health, hormonal health, gut health, sexual health, and more.*
Nitric Oxide is naturally made in the human body. As we age, we produce less of it — and over time, the blood vessels involved in naturally producing NO become less efficient due to free radical damage, inactivity, and poor diet. At the same time, deterioration of veins and arteries results in overall poor circulation, leading to a myriad of health issues.
Nitric Oxide can be re-introduced into the body through a nitrate-rich diet, but the realities of modern eating habits make simple supplementation programs — like Berkeley Life’s — a much more efficient and effective solution.
Research and Thought Leadership
Nitric Oxide research continues to grow at a rapid pace. To leverage findings from these studies and apply them directly to product improvements and innovation, we rely on the help of industry-leading practitioners and thought leaders in the functional and preventative healthcare space. The Berkeley Life scientific advisory board advises on the latest scientific findings, which we directly apply in continuously educating and supporting our practitioners.
If you are a practitioner interested in learning more about the science of Nitric Oxide, please schedule a meeting with our team, who can provide you with access to further research and thought leadership around Nitric Oxide and its health benefits.
