Our approach

Editorial, not promotional

Grenval is written and edited by an independent team with a background in health communication. Every article is reviewed for accuracy against publicly available research before it is published.

We do not sell products, and nothing on this site is written to persuade a reader toward a purchase. Our aim is simply to explain, in accessible language, what current evidence and public health guidance say about the male heart.
