Inositol hexaphosphate (IP6) is a naturally occurring vitamin-like substance found in humans, animals, and many plants, especially cereals, nuts, and legumes. It is marketed as a supplement to support natural cellular defense and is added to food to keep it from spoiling. Some people use IP6 to treat and prevent cancer, to reduce side effects of cancer treatment, for anemia, diabetes, and many other conditions, but there is no good scientific evidence to support these uses. However, lab studies suggest anticancer and antiangiogenic effects of IP6. IP6 might help treat and prevent cancer by slowing down the production of cancer cells. It might also bind to certain minerals, decreasing the risk of colon cancer. IP6 is also an antioxidant. When taken by mouth, IP-6 is LIKELY SAFE when used in amounts found in foods. IP-6 is POSSIBLY SAFE when used as a medicine, short-term. Taking IP-6, 600 mg two times per day for up to 2 weeks, appears to be safe. There isnt enough reliable information to know if IP-6 is safe when used long-term or in larger amounts.
