Do nitric oxide boosters work?

Nitric oxide boosters can be effective in increasing the availability of nitric oxide in the body, which is involved in various physiological functions, including blood flow and vasodilation. Dr. Rena Malik mentions that supplements like L-citrulline and L-arginine are used to enhance nitric oxide levels. L-citrulline, in particular, is converted to L-arginine in the body, leading to sustained effects in the bloodstream. These supplements are noted to have some efficacy in sexual medicine 1.

However, the regulation and quality control of these supplements can be problematic as the industry is largely unregulated. This can lead to inconsistencies in the actual content of the supplements compared to what is stated on their labels, making it difficult for medical professionals to recommend them with certainty 1.

Even though there is scientific backing for the efficacy of these boosters in increasing blood flow or enhancing sexual function, the overall quality concerns mean that consumers should exercise caution and ideally choose products from reputable sources.
