Medical disclaimer: This page is educational and not medical advice. Melonex is a dietary supplement for healthy adults (18+) and is not intended to diagnose, treat, cure or prevent high blood pressure, heart disease or any disease. It is built on the amino acids L-Arginine and L-Citrulline, which support nitric oxide and may lower blood pressure and widen blood vessels; if you take blood-pressure medication, nitrates, erectile-dysfunction drugs (PDE5 inhibitors), or blood thinners, combining them could drop your blood pressure too far — show your doctor the label, and never stop or change prescribed medication. L-Arginine may also trigger herpes outbreaks in susceptible people. Persistent high blood pressure needs medical evaluation — please see a doctor. For adults only (18+).
