Noni juice (Morinda citrifolia)

Tier 3 — weak evidence · Immunity · Antioxidant claims

A tropical fruit juice marketed with broad health claims. Most studies are small, poorly designed, or industry-funded. Antioxidant content exists but is not exceptional compared to common fruits. Several cases of hepatotoxicity have been reported in Europe (causality debated). Contains vitamin K which can interact with blood thinners. Not recommended over evidence-based alternatives.

Dose: 30–60 mL/day noni juice; limited clinical evidence; liver toxicity cases reported
