Nitric Oxide/Erection Health Support Supplement for Men - 120 Tablets - High Dose L-Citrulline/Korean Red Ginseng

Free Shipping

Why We Love It

Supports enhanced erectile function.
Formulated with scientific backing.
Improves blood circulation naturally.

Main Highlights

Our no nonsense, science backed, daily supplement supports your erections by increasing the amount of available Nitric Oxide in the erection mechanism, which in turn leads to improved function and increased blood flow to your penis. Each serving (4 Tablets Daily) provides 1600mg L-Citrulline and 400mg Korean Red Ginseng.
We are a science led men’s health company - our supplements have been developed after extensive research in collaboration with leading men’s health physicians and packed with ingredients that have robust scientific evidence to support their use. Our philosophy is that we include effective doses of the ingredients that we know have a benefit rather than small doses (and thus not therapeutic) of many things that there is no evidence of their efficacy.
L-citrulline is an amino acid naturally made in your body, converted in the kidneys into L-arginine, another amino acid. L-arginine is then converted into nitric oxide, which helps improve blood flow by helping your blood vessels relax and work better. It also helps fight the natural aging process in the penis that happens to all men over the age of 30.
