Noni juice (pronounced NO-nee) is sourced from the fruit of the noni tree. Also known as Morinda citrifolia or Indian mulberry, the noni tree is a small, flowering tree found in Tahiti and Hawaii.

Uses for Noni Juice

Noni juice and fruit has a long history of use in Polynesia for health conditions such as constipation, diarrhea, skin inflammation, infection, and mouth sores.

Traditionally, noni leaves were used topically as a poultice to aid in wound healing.

Noni became popular in the 1990s when the juice was marketed extensively as a health beverage in the United States by network marketing companies.

Benefits of Noni Juice

While preclinical laboratory research suggests that compounds in noni may have tumor-fighting properties, there is a lack of clinical studies on the safety and effectiveness of noni.

Many of these studies used high doses (or concentrated noni compounds) that would be difficult to realistically and safely obtain by drinking the juice.

Like many fruits, noni is a source of vitamins, minerals, and antioxidants (compounds that protect your body's cells from damage). Other antioxidant-rich fruit include blueberry, raspberry, as well as goji berryacai berrymangosteencamu camu, and tart cherries. By protecting the body's cells, antioxidants have the potential to prevent diseases like diabetes.

Where to Find It

Typically sourced from Tahitian or Hawaiian noni fruit, noni juice is available in health food stores. The fermented juice or juice extract is most common, but noni is also available concentrated in powder, tablet, or capsule form. Noni tastes bitter and has a strong smell, so the juice is normally sweetened.

Side Effects and Safety

Noni juice is high in potassium and should be avoided by people with kidney, heart, and liver disease and those taking potassium-sparing diuretics, angiotensin-converting enzyme (ACE) inhibitors, or angiotensin receptor blockers. Consuming noni may result in hyperkalemia (a dangerous elevation of potassium levels).

Noni juice is also high in sugar, so people with certain conditions such as diabetes should use caution when introducing it into the diet.

The noni plant contains anthraquinones, compounds found to be toxic to the liver and carcinogenic. A small number of case reports of liver injury (including hepatitis and liver failure) have been attributed to noni consumption. For example, noni juice was linked to acute liver toxicity in a 14-year old boy, according to a case report. While there were additional factors in many of the case reports and the risk when using commercial products appears to be lower, It's important to note that the U.S. Food and Drug Administration (FDA) doesn't analyze the content of dietary supplements before they are sold on the market.

If you are taking blood-thinning medication such as coumadin or have a bleeding disorder, you should avoid noni. Noni may also interact with other medications and treatments, such as phenytoin, UGT (uridine 5'-diphospho-glucuronosyltransferase), and chemotherapy and radiation therapy.

Noni hasn't been tested for safety in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications. Get further tips on using dietary supplements.

A Word From Verywell

While there is interesting preclinical laboratory research on noni extracts, so far, claims that they can treat cancer, diabetes, or any other condition in humans have yet to be scientifically proven. There are also concerns about the safety of certain noni juice products. If you're still considering trying noni juice, be sure to speak with your health care provider to discuss whether it's appropriate for you.
