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.

Longevity & Anti-Aging
Scientific approaches to lifespan extension
Foods for deep sleep: tryptophan, magnesium, melatonin from food. Let's look at what to eat in the evening and how to improve sleep quality.
Glycation is a process in which sugars "glue" proteins together, forming AGEs. These damaged structures accelerate tissue aging. Let's look at how to reduce them with diet and nutraceuticals.
Autophagy and fasting: how the body "cleans itself". Let's look at the mechanism, benefits and how to trigger it. Brief and clear.
mTOR and AMPK are two "conductors" of cellular metabolism. One drives growth and synthesis, the other energy saving and cleanup. Let's explore how diet, fasting and supplements manage this balance.
Muscles and metabolism in 60+: how to keep strength against sarcopenia. Protein, HMB and creatine, exercise and food sources.
Hormesis: how moderate stress (sauna, cold, physical exercise) extends life. Mechanisms, data and practical approaches.
Nutrition
Healthy eating principles and dietary approaches
