Here's the science!

I see you're not getting much help answering your question, but here's the science. Mangosteen works because it has xanthones. Xanthones are super stable biologically active molecules that are supercharged antioxidants and have powerful anti-inflammatory properties. This is important, because studies now show that most diseases originate in either free-radical damage or inflammation. The first xanthone was identified in 1855 (alpha-mangostin). Xanthones have been found in laboratory studies to be active against various infectious agents, cholesterol damage, cancer cells, etc. They are over 200 xanthones that have been identified in nature so far, more than 40 of which are found in the mangosteen fruit, which is more than any other substance in nature. Only about 7 or 8 xanthones have been really studied so far by scientists, but of those, the information is compelling. In 2004 in an article in Molecular Pharmacology, Japanese researchers said that gamma-mangostin, one of the xanthones found in mangosteen, is an effective COX-2 inhibitor. For those of you who don't know what COX-2 inhibitors are, you may be more familiar with Vioxx and Celebrex. Mangosteen has 20 to 30 times the ability to absorb free radicals than most fruits and veggies. Its ORAC (Oxygen Radical Absorbance Capacity) score is 17,000 compared to pomegranates (3,037), blueberries (2,400), and carrots (200). Xango brand is the only mangosteen formulation that uses the whole fruit mulched to get all the xanthones. Other cheapie imitators use an extract which has a few, but not all of the xanthones in the mangosteen fruit, which will make them less effective. Go to

and enter xanthone and xanthones. There are close to 2000 studies. Pick whichever one you like. THAT is why you should drink it. Let me know if you have any more questions.
