There are a ton of sites devoted to noni juice. Of course ALL of them sell it, so any information you find there will be with the purpose of making a sale. Noni juice is an MLM product, which means the main purpose of the product is to make money.
The resident nutritionist with BellaOnline has written a very helpful article on noni juice.

Apparently, noni juice is mostly sugar water.

Supplement Noni (Morinda citrifolia)
Description Noni (Morinda citrifolia), is also known as Tahitian Noni and Indian mulberry. The plant is a small tree found in the Pacific islands and Polynesia. The fruit of the Noni tree is foul-smelling and tasting and resembles a cross between a warty avocado and a pitted mango (not a pretty sight). Noni fruit passes thru several stages of ripening, where it turns from green to yellow to white - and is generally regarded as becoming more disgusting with each stage of ripeness.
Claims · You name it - they claim it…
· "Miracle cure" for Arthritis, Infections, Cancer, Chronic Fatigue, Diabetes, Heart Disease, Digestive disturbances, Inflammation, and many others.
Theory Only if you were starving to death, would you force yourself to eat noni fruit. Because of its foul odor and bitter taste, nobody except the most desperate Polynesians would force themselves to consume noni (and only during times of famine or widespread sickness). Traditional Polynesian healers ("medicine men") have reportedly used noni fruit for treating everything from constipation to ankle sprains - and there are accounts in traditional Chinese medicine (TCM) of noni roots being effective for "strengthening" the digestive system.
Scientific Support Despite the fact that noni has been heavily promoted by multi-level marketing companies for virtually every ailment under the sun, there is no convincing evidence that it is has any beneficial effects for any specific condition. Studies do exist, however, to show that noni juice provides a small measure of antioxidant activity (but so do the juices of almost all fruits) and even a few unique polysaccharide compounds that may help immune system function - so these findings may lend a shred of credence to common claims of anti-inflammatory and anti-cancer effects.
Safety: Noni is not associated with any adverse side effects. Commercial preparations are extensively processed to remove and/or mask the horrendous taste and smell of the native noni fruit, so there is probably more of a safety concern from the added flavors, colors and sweeteners in these concoctions than from the actual noni fruit.
Value Some people will always assign a high mystical value to bad-tasting things from far-off islands - and this is certainly the case with noni juice. Our advice, if you want to drink something that is truly good for you, is to try some orange juice (more antioxidants than noni plus potassium that noni lacks), a V-8 (chock full of carotenoids) or even some apple juice (also packed with antioxidants).
Dosage Commercial noni products are available as juice, tablets and capsules - but there are no scientifically accepted dosage levels for these products. The juices tend to be the most heavily promoted (hyped as cure-alls) with typical dosage recommendations in the range of 4-6 ounces per day. Concentrated forms of the juice may be recommended in lower daily doses of 1-2 tablespoons.
Black vinegar: I can't find any reputable medical sources that even mention it, or references to published studies. I'd be inclined to think it's just hype, like surrounds so many natural remedies. Products like these are usually backed only by references to myserious studies in foreign countries that can't be verified. I don't trust anything without valid proof. I'm a true skeptic, lol.
