What Does a Nitric Oxide Booster Do for Men? Benefits, Risks & Safety
If you've seen nitric oxide boosters marketed for men, you may have wondered what they actually do.
Are they mainly workout supplements? Can they improve circulation? Do they have anything to do with erections? And are they safe for everyone?
The short answer is that nitric oxide (NO) is a naturally produced signaling molecule that helps blood vessels relax and widen. Supplements marketed as nitric oxide boosters generally do not contain nitric oxide itself. Instead, they typically contain ingredients intended to help the body produce or increase the availability of nitric oxide.
That matters because blood flow plays an important role in cardiovascular function, physical performance, and normal erectile function.
But the supplement market often makes the subject sound simpler than it really is. Different ingredients have different levels of evidence, and a nitric oxide supplement is not automatically a treatment for erectile dysfunction or another medical condition.
