Knowledge base
Browse by category
Popular supplements, vitamins, adaptogens, functional mushrooms, diets and more — one place, vetted sources.
Suplementy, witaminy i minerały — od kreatyny i kolagenu po witaminę D3 i magnez — z dawkowaniem i suplementacją opartą na dowodach.
Creatine
One of the most thoroughly studied supplements in the world — supports strength, muscle mass and, according to newer research, cognitive function.
Collagen
Collagen peptides are often used as a supportive measure for skin elasticity and joint comfort — the evidence is promising but still limited.
Vitamin D3
Functionally it acts like a steroid hormone — deficiencies are widespread in Poland, especially during autumn and winter.
Magnesium
A cofactor for more than 300 enzymatic reactions — essential for neuromuscular function, sleep and energy metabolism.
Zinc
A trace element essential for the work of over 300 enzymes in the body — its deficiency, more common than widely believed, affects immunity, wound healing, and hormone balance.
Omega-3 Fatty Acids
The polyunsaturated fatty acids EPA and DHA have one of the strongest evidence bases among cardiometabolic supplements — but the effect depends heavily on baseline blood levels, not just the dose on the label.
Vitamin B12
The only vitamin the body can store in the liver for years — yet its deficiency is often mistaken for dementia, depression or plain fatigue, because neurological changes can precede any abnormality in a standard blood count by years.
Niacinamide (Nicotinamide)
A rare ingredient that genuinely spans two different worlds: as vitamin B3 taken orally it prevents pellagra and serves as an NAD+ precursor, while as a skincare ingredient it regulates sebum, strengthens the skin barrier and brightens discoloration — with real, if differently weighted, clinical evidence on both sides.
Xylitol and Dental Health
A sweetener that cavity-causing bacteria can't effectively ferment the way they ferment sugar — unlike sucrose, xylitol may limit their growth and adhesion to enamel, a mechanism studied for decades as a practical element of dental caries prevention, though popular articles often overstate how strong and unambiguous that evidence actually is.

Frequently asked questions
No. Our content is educational and summarizes the available scientific literature. It doesn't replace a consultation with a doctor, pharmacist or dietitian — always discuss supplementation and lifestyle changes with a specialist, especially if you have an existing condition or take medication.
Every entry in the knowledge base references specific scientific studies (with links to the sources), and content is prepared by the VitMode editorial team from primary sources. Cited PubMed records are verified automatically against the NCBI database (identifier, title, year).
Every entry carries a label: 'strong evidence' (numerous clinical trials, meta-analyses), 'moderate' (promising but limited studies), 'early-stage' (mostly animal studies or small pilot trials), or 'hypothesis' (a plausible mechanism, but poorly studied clinically).
Yes — every knowledge base page has a comments section, and factual errors can be reported directly to our editorial team. Verifying submissions is part of our editorial process.
