This is a very important question for those who take products containing these power-packed antioxidant compounds known as xanthones. Our research has found that there are synthetically-derived xanthones. But most significantly, the published studies that tested the benefits of synthetic xanthones came back with very mixed results.
I believe that the best source of natural xanthones comes from the mangosteen fruit and its outer pericarp (rind). The Vemma Nutrition Program™ uses mangosteen fruit and a potent, standardized extract from the mangosteen pericarp (standardized for 10% xanthones). This standardized form offers the highest levels of natural xanthones of all the products we’ve tested.
If a product on the market is said to contain xanthones, my recommendation is to make sure the xanthones you take are natural, have the highest levels and come from the best source you can find. Then, research to see if the company backs their product with testing.
Another benefit of Vemma® is that its owner, BK Boreyko, owns the state-of-the-art manufacturing facility where Vemma is produced. I’m in charge of every aspect of testing, manufacturing and quality control. BK requires I manufacture the best, most potent mangosteen product on the market. He expects the best and Vemma delivers it. You won’t find a more potent, complete mangosteen product anywhere. I guarantee it!
