“Although researchers are in the process of identifying and measuring additional xanthones, this study, published in the Journal of Separation Science, ensures a more consistent and reliable marketing of mangosteen products to consumers relative to claims of xanthone content,” said Walker.
Whole fruit drives absorption
A pre-clinical, preliminary 28-day study of XanGo Juice by Charles River Laboratories Montreal identified the bioavailability of xanthones to determine how many xanthones are actually absorbed and the pathway they travel.
Study director Susan McPherson, MSc, senior research scientist at Charles River Laboratories, said preliminary research findings demonstrate that the proprietary whole fruit formula in XanGo Juice leads to high levels of xanthone absorption.
Ongoing research shows high absorption of xanthones in defined dosages, with elements of the whole mangosteen fruit as a delivery vehicle. Unnaturally elevated levels of xanthone consumption actually were shown to result in decreased absorption efficiency.
Preliminary results also showed long-term daily consumption of XanGo Juice to increase levels of xanthones in the blood.
"This is an issue of quality over quantity,” said Mike Pugh, manager, research and development at XanGo. “These preliminary findings add further context to the published xanthone measurement study. Ongoing research shows artificially inflating or manipulating a product with xanthone extracts may not add any value.
The mangosteen presents more value in its whole fruit form, as presented in XanGo Juice. There are many other phytochemicals found in the fruit that have beneficial effects which are lost in extraction or jeopardized when the natural balance of the fruit is manipulated."
XanGo Juice is produced through a proprietary whole fruit formula based on a puree of the entire mangosteen. The whole mangosteen fruit contains 39 different xanthones. The rind of the mangosteen is considered nature's most abundant source of xanthones. Xanthones, a unique class of phytonutrients, possess a range of powerful antioxidant properties.
