Welcome to the VitalFit Knowledge Hub
In the VitalFit Knowledge Hub you'll find articles on micronutrients, sports nutrition and well-being — written for people who want to inform themselves without having to wade through scientific texts or marketing promises. If you want to jump straight to a concrete topic, good entry points are Magnesium and muscle function or Vitamin D in winter — two of the most common everyday questions.
What you can expect here
- Background knowledge on vitamins and minerals that's actually relevant in everyday life
- Daily requirements according to DGE — so not "somewhere between 200 and 2,000 mg", but concrete numbers
- Tables on foods and intake forms that let you assess for yourself where you stand
- Clear answers to common questions, without sprawling disclaimers
What we rely on
Every effect-related statement in our articles comes from a single source: the EU list of authorised health claims (Regulation 432/2012). EFSA reviewed this list scientifically — and it defines what may legally be said about a micronutrient at all. Quantity information and reference intakes come from the German Nutrition Society (DGE), safety assessments from the German Federal Institute for Risk Assessment (BfR).
What you won't find here: cure promises, before/after stories, outcome promises like "X kg in 4 weeks", or marketing-speak like "strengthens the immune system". Such statements are — for good reason — not permitted in the EU, and we stick to that.
Personal evaluation is available separately
The articles here are general information. If you want to know what's sensible for you personally, take a look at the Vital-Check. Three minutes, free of charge, then you'll receive your individual evaluation by WhatsApp or email — no diagnosis, no sales pitch, no long phone calls.
Frequently Asked Questions
Are diseases treated here?
No. The knowledge hub provides general information on micronutrients and well-being. For health-related questions please speak with your doctor.
Which sources are used?
We rely exclusively on official sources such as EFSA, DGE, BfR and peer-reviewed studies. Manufacturer websites are not accepted as evidence for effect-related statements.
