A pre-clinical, preliminary 28-day study of XANGO® Juice identified the bioavailability of xanthones to determine how many xanthones the body actually absorbs and the pathway they travel. A validated xanthone analysis method was used to measure the quantities of the alpha-mangostin xanthone found in blood plasma.

Charles River Laboratories, a pre-clinical lab that was established in 1947. It is world renowned for its research models in safety, pharmacokinetics, and in-vitro work. It employs 7,500 employees, including 500 researchers that include PhDs, MDs and DVMs.
The validated plasma method used LC-MS/MS technique to identify and quantify the amounts of alpha-mangostin in the plasma. This new analysis can quantify levels as low as 1 nanogram per ml (ng/ml).
The preliminary research demonstrates that the body absorbs xanthones in low dosages and that very high levels of xanthone consumption actually result in decreased absorption efficiency. In addition, preliminary results showed long-term daily consumption of XANGO Juice increases the levels of xanthones in the blood.
More specifically, the study showed the following regarding alpha-mangostin:
This study allows for a solid foundation for future clinical trials. Also, these preliminary findings show artificially inflating a product with xanthone extracts does not add any value.
