Health, sleep and fitness
Lifestyle, nutrition, supplements and exercise, including the practical size of any effect.
Evidence before claims
Check the evidence before the claim.
We use AI to search research papers, clinical guidelines, and public-health sources across languages, then publish the sources, effect sizes, safety findings, conflicting evidence, and remaining uncertainty.
This is not an AI clinic.
We do not diagnose individuals, choose treatment, or instruct people to change medication. We organize research available at the time of review.

Research areas
What we investigate
Skin, aging and hair
Specific outcomes such as hydration, elasticity, wrinkle depth and hair density rather than vague rejuvenation claims.
Weight and body fat
Weight, water, muscle and fat are separated so a change on the scale is not automatically called fat loss.
Conditions and treatment
We summarize what current guidelines consider, and at which stage, without choosing treatment for an individual.
Timing
Whether morning, evening, fasting or fed administration changes absorption, outcomes or adverse effects.
Route of administration
Oral, sublingual and medically administered routes are compared using clinical outcomes and safety, not absorption alone.
