Summary & Key Takeaways
Noni is a traditional botanical with a long history of use in Polynesian and Asian medicine. While it contains potentially beneficial compounds and has shown promise in preliminary research, high-quality clinical evidence remains limited for most claimed benefits.
Proceed with Caution: The risk of liver and kidney toxicity, high potassium content, and numerous drug interactions make noni potentially dangerous for many people, particularly those with existing health conditions or taking medications.
Bottom Line: If considering noni, consult a healthcare provider first, especially if you have kidney/liver issues or take medications. Choose third-party tested products, start with low doses, and monitor for adverse effects. The potential risks may outweigh uncertain benefits for many individuals. Consider well-researched alternatives for specific health goals.
