Isoflavones are naturally occurring, hormonally active substances found in soy and other foods. Chemical modifications of isoflavones have been studied as possible alternative treatments for various conditions. One of these, ipriflavone, was developed primarily for treating osteoporosis. Methoxyisoflavone is a chemical derivative of ipriflavone, but it is marketed as abodybuilding aid.

Methoxyisoflavone is not a nutrient and is not supplied to any meaningful extent in food. However, it is possible that, once in the body, natural isoflavones, such as daidzein, may be converted to some extent into methoxyisoflavone.
