What Are the Benefits of Noni Fruit?

Noni is a tropical, fruit-bearing tree native to the Polynesian Islands. In the United States, noni is available as a dietary supplement in the form of juice, capsules, tablets and powders. Traditionally noni has been used to treat diarrhea, wounds and certain skin conditions. Today, noni is promoted for weight control, healthy blood glucose, managing cholesterol and as a general health tonic. Talk to your health care provider before taking noni supplements, especially if you have a medical condition.

Cholesterol Benefit
Noni fruit possesses potent lipid-lowering ability, as shown in a study published in "Scientific World Journal" in October 2012. Researchers found noni significantly reduced cholesterol and triglycerides in smokers with elevated lipid profiles. The volunteers drank noni juice for 30 days,and at the end of the study period their cholesterol had dropped 20 to 25 percent and their triglyceride level was 29 to 41 percent lower.

Anti-obesity Benefits
Noni promotes weight control in overweight men and women, according to a study published in the "North American Journal of Medical Sciences" in December 2011. Researchers conducted a 12-week study involving 16 women and six men who supplemented with noni during a diet and exercise program. Participants experienced a highly significant average reduction in body fat; the average weight loss was 17.5 pounds for the women and 21.7 for the men.

Anti-diabetic Benefits
Researchers tested blood sugar-lowering properties of fermented noni juice by giving it to diabetic rats for 20 days and observing the effect. They found that noni significantly reduces fasting blood sugar similarly to the way diabetes medication does. In addition, noni exhibited liver-protective properties, according to the study, which was published in the October 2010 issue of the "Evidence Based Complementary and Alternative Medicine" journal.

Noni Supplement Safety
Several reports of liver toxicity were linked to taking noni juice products, although such reports are rare. Noni may interfere with the effectiveness of blood-thinning medications and chemotherapy drugs. In addition, noni is rich in potassium and may cause problems if you must adhere to a low-potassium diet. Some noni products are high in sugar, so choose those with low sugar if you have diabetes. Take noni only under your doctor's supervision if you have any health issues.
