Are you familiar with nitric oxide? You see a great many supplement products now with names coined around the terms “nitric oxide” and its common abbreviation; “NO”. Nitric oxide is a highly desirable natural compound that promotes better circulation by inducing a natural process known as vasodilation. There are many reasons people may want to increase nitric oxide production and vasodilation; better blood pressure, improved erectile function and muscle fullness are the most common. In response, the supplement industry has created a whole category of supplements to promote vasodilation (” nitric oxide boosters”) most of which rely on, essentially, a single amino acid to get job done. A new study suggests that soy isoflavones are effective NO boosters, too, which could pave the way towards much more effective NO products.
