Limited RCTs or observational studies with plausible mechanisms. Promising but needs more research.

Why This Exists
About fen
The natural health space is full of noise — miracle cures, influencer endorsements, and marketing dressed up as medicine. We started fen because we believe people deserve better.
Every article we publish cites peer-reviewed research. Every supplement, herb, and practice gets an honest evidence rating. We don't sell products — we help you understand what the science actually says, so you can make your own decisions.
fen is named after natural wetland ecosystems — places where diverse life thrives in balance. That's what we believe health should be: grounded, diverse, and rooted in nature's own evidence.
