Thai-Go
Mangosteen Juice Research

NSP carefully researched ingredients high in antioxidant activity and selected only the best. In a study conducted by an independent laboratory¹ Thai-Go clearly outperformed other leading competitors in ORAC capacity (charts a measure of a product’s antioxidant strength). Another study showed that Thai-Go is three times better in stimulating immune response ²than its closest competitor.

SCIENTIFIC SUPPORT
Antioxidants are getting increasing attention from the scientific community. Promising studies have led the USDA to state, “Eating plenty of high-ORAC fruits and vegetables—such as spinach and blueberries—may help slow the processes associated with premature aging in both body and brain.”
Xanthones have also attracted attention from scientists and researchers who are discovering that these compounds support the immune, structural, and digestive systems, and the brain and the skin. 
Studies have demonstrated that xanthones have the ability to offer support in the following areas:

Cholesterol concerns  (1,2)

Inflammation/pain response/Cox 2 inhibition  (3)

Skin conditions  (4)

Microbiological balance  (5)

Allergy support  (6)

Immune system support  (7)

About Mangosteen Xanthones

Xanthones are in a class of plant derived nutrients called "phytonutrients." They have been demonstrated in numerous scientific studies to hold tremendous nutritional value.  Found to exhibit strong antioxidant activity xanthones neutralize free radicals in the body and enhance and support your body's immune system. Although xanthones exist in small amounts throughout nature, it is found in concentrated amounts in the Pericarp (outer layer) of the mangosteen fruit.

There are over 20 known forms of xanthones naturally occurring in the Pericarp, the two most widely studied are Alpha Mangostin and Gamma Mangostin.

Why haven't I heard about xanthones from mangosteen if they are so great?

The people of Southeast Asia are very familiar with the prized mangosteen fruit and Asian Health Practitioners have long made use of Pericarp for a myriad of nutritional uses. The mangosteen fruit, however, has never been introduced to the Western world and much of the science behind xanthones is predominantly available to those in the medical community until recently. Many of the clinical studies on xanthones have been done in universities and testing facilities throughout Asia and have recently started to catch the attention of Western researchers.

What is the most potent source of xanthones?

According to the research, the most concentrated source of xanthones found in nature is in the Pericarp (rind) of the mangosteen fruit. The majority of clinical studies on xanthones specify that the xanthones used were from the mangosteen Pericarp.

I eat a balanced diet. Am I getting xanthones from my food?

No. The xanthone family of phytonutrients can be found in trace amounts in certain fruits and vegetables, however, the pericarp of the mangosteen is the premier source where these nutrients are found in concentrated amounts. Most scientific studies actually name the mangosteen pericarp as the source of xanthones.

What makes xanthones from mangosteen fruit so special?

What is amazing is that the Mangosteen (which, has no connection with the mango), has never been utilized for its multiple health benefits in North America or Europe despite its history and popularity as a folk remedy in Asia and South America. Until recently, it has been one of Nature's best kept secrets.
