Mangosteen is likely safe for most people, but it may increase the risk of bleeding. Consult your healthcare provider before taking a new supplement or drastically changing your diet. Mangosteen is a tropical fruit native to Southeast Asia. It is consumed as food and as medicine.
Data from in vitro and animal studies revealed that it has antioxidant, anti-inflammatory and antiproliferative effects against cancer cells. Xanthones, the main components of the mangosteen fruit, have been implicated in these effects. It has not yet been studied in humans. However, despite the lack of clinical evidence, mangosteen products are marketed to cancer patients as dietary supplements.
Cancer patients should be careful before consuming mangosteen products, as they can interact with cancer treatments and also affect blood sugar levels.
