I've heard that drinking noni juice may lower my cholesterol. Is this true?

Answers from Thomas Behrenbeck, M.D., Ph.D.

There's no evidence that noni (NO-nee) juice reduces cholesterol. Noni juice has gained popularity as a tonic for everything from arthritis and depression to heart disease and cancer. But there's no evidence that noni juice is effective in treating any of these conditions. Noni juice may also interact with some blood pressure medications.

As with many fruits, the noni fruit is a source of vitamins and minerals, as well as antioxidants. Antioxidants can protect the body from age-related changes and certain diseases, such as cancers.

The juice has an unpleasant taste and odor, and certain people should be cautious when drinking noni juice. Noni juice is high in potassium, and could raise your potassium to dangerously high levels (hyperkalemia) if you drink a large amount of the juice. For this reason, it should be used with caution — if at all — in people who:

  • Have chronic kidney disease
  • Take certain blood pressure medications, such as potassium-sparing diuretics, angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs)
