Ipriflavone
A synthetic derivative of the isoflavone daidzein. Ipriflavone was marketed as a non-estrogenic alternative treatment to counter post-menopausal bone loss and osteoporosis, on the strength of in-vitro and animal studies. Controlled studies in humans, however, have had conflicting results. The safety of ipriflavone has also been questioned.
It’s also been claimed that ipriflavone and/or certain derivatives (such as 5-methyl-7-hydroxyisoflavone) can enhance muscle growth, but definitive proof is lacking.
Ipriflavone may also be known by a chemical name, 7-isopropoxyisoflavone.
