Supplement ratings
built on studies, not hype.
NMN, Ashwagandha, Curcumin and more — rated by clinical evidence quality and EU regulatory status. We assess product transparency and research quality, not health effects. Most longevity supplements carry no approved EU health claims.
How MikroScore works
Nutrient Check
15 questions — we estimate which nutrients you may be at risk of under-consuming, based on your diet and lifestyle.
Start check →Ingredient Dossiers
RCTs, meta-analyses, and EFSA assessments — each ingredient rated on a 1–5 evidence scale, with EFSA health claim status flagged.
All 119 ingredients →Research Review
New papers, meta-analyses, and trial updates — curated weekly across 119 tracked ingredients. No hype, just evidence.
Latest review →Product Reviews
Concrete products rated by price per dose, purity, label accuracy, and third-party certification — not just ingredient quality.
All 298 products →Marketing claims, evidence checked
Claims Check
We take supplement marketing claims and check what is actually supported by studies, EFSA assessments, or sound evidence — and what is exaggerated or false.
"Is krill oil better than fish oil?"
Krill oil may raise blood omega-3 levels more than fish oil. That still does not prove a clear health advantage over fish oil.
"Ashwagandha eliminates stress and lowers your cortisol permanently"
RCTs confirm cortisol reductions of 14–27% during supplementation. Effects reverse after stopping. 'Permanent elimination of stress' is unsupported by any study.
"Berberine is the natural Ozempic"
Berberine is marketed as 'natural Ozempic', but its evidence base and effect sizes are incomparable to those of the GLP-1 drug semaglutide.
Ingredient dossiers
Show all →Fucoidan
Fucoidan is a sulfated polysaccharide from brown seaweed with growing evidence for prebiotic gut effects, muscle health, and cardiovascular markers.
L-Glutamine
L-glutamine is the most abundant free amino acid in the body. Clinically well-supported in critical care; evidence for oral supplementation in healthy individuals is more limited.
Alpha-Liponsäure (R-ALA)
Mitochondrial antioxidant with dual water/fat solubility. R-form significantly more bioavailable than racemic mixture. Evidence strongest for diabetic neuropathy.
Saffron (Crocus sativus)
Saffron is mainly studied for mood, stress, and PMS. Human trials are interesting, but still too small and narrow to justify broad health claims or premium pricing narratives.
5-HTP (5-Hydroxytryptophan)
5-HTP is a serotonin precursor crossing the blood-brain barrier. Used for sleep and mood. Critical: avoid with SSRIs or MAO inhibitors due to serotonin syndrome risk.
Acetyl-L-Carnitin
ALCAR is the brain-accessible form of carnitine popular in cognitive and healthy aging stacks, but evidence is solid rather than remarkable.
