Our Mission
Making evidence-based health science accessible to everyone
In a world where every other blogger advertises "miracle" supplements and marketing companies spend millions promoting questionable products, we decided to create an island of objective information.
VitaWix is a project that prioritizes evidence-based medicine and scientific research. We don't sell supplements. We don't advertise dubious brands. We simply collect, analyze and clearly explain scientific data about vitamins, minerals and their impact on health.
- We rely only on data from peer-reviewed journals (PubMed, Cochrane, The Lancet)
- We critically evaluate research quality and aren't afraid to report ambiguous results
- We explain complex biochemical processes in simple, understandable language
- We regularly update information as new research emerges
Evidence-Based Medicine
Every article on VitaWix goes through source verification. We only cite data from peer-reviewed scientific journals.
