The supplement industry has a trust problem
A $180 billion market built largely on unverified promises. Here’s what makes finding real evidence so difficult.
Unproven claims everywhere
Most supplement claims are based on animal studies, in-vitro research, or anecdotal evidence — not human trials.
Marketing disguised as science
Brands use buzzwords like "clinically tested" while citing low-quality or industry-funded studies.
Hard to find real answers
Sorting through thousands of studies to find rigorous, unbiased evidence takes expertise most people don't have.
How Proof.Fit works
From clinical trial to actionable insight — in three steps.
We find the gold standard
We search for Randomized Controlled Trials — the most rigorous type of clinical study, where participants are randomly assigned to treatment or control groups.
AI extracts the evidence
Our AI-assisted analysis reads each trial and extracts findings with clear, measurable effects on specific human health outcomes.
