Quick answer: Melonex is marketed for healthy blood flow, normal blood pressure, circulation and heart support. Arginine and citrulline studies at several grams a day found small drops in blood pressure. Benefits are not guaranteed, and it is not a treatment for high blood pressure.
Here are the brand's goals, with what research says about the listed ingredients. These are not medical claims.
1. Healthy blood flow
Nitric oxide helps blood vessel walls relax. Arginine is its raw material, and citrulline raises arginine levels.
2. Normal blood pressure
Meta-analyses found average systolic drops of a few mmHg at gram doses. That is far smaller than the effect of most prescription medicines.
3. Circulation and exercise
Citrulline malate is studied for exercise performance and muscle soreness, with mixed results.
4. Heart support
There is no evidence that arginine prevents heart attacks, and it should not be used after one.
5. Other claims
The brand's infographic mentions focus and vision. Melonex has no study on these.
What it is not
- A treatment for high blood pressure or heart disease
- A replacement for medicine, diet or exercise
- A proven finished formula
