WHAT IT DOES
A tropical fruit juice with centuries of traditional use in Polynesia, but limited modern clinical evidence.

DOES IT WORK?
Noni has a devoted following and long traditional use in Pacific Island cultures. It contains some interesting compounds (iridoids, scopoletin). But the clinical evidence is thin. A few small human studies suggest antioxidant and anti-inflammatory effects, but nothing conclusive. Mostly riding on traditional reputation.
