Everyone deserves to know what's in their products
We believe transparency is a right, not a privilege. Kleen.ai uses data-driven analysis to cut through marketing claims and give you honest, science-backed product scores.
The Problem
The supplement industry operates with shockingly little oversight. Here's what the data shows.
💊
70%
Contain undisclosed fillers
Independent lab tests reveal that the majority of supplements contain ingredients not listed on the label, from magnesium stearate to silicon dioxide.
💰
$50B+
Industry with minimal oversight
The supplement market generates over $50 billion annually in the U.S. alone, yet the FDA does not require pre-market approval for supplements.
⚠️
23,000+
ER visits per year
Adverse events linked to dietary supplements result in over 23,000 emergency room visits annually in the United States.
🔍
~5%
Are third-party tested
Only a small fraction of supplements undergo independent verification. The rest rely entirely on manufacturer claims with no external validation.
