Ipriflavone is a synthetic product based on a substance that occurs naturally in some plants (isoflavone).
It is an over-the-counter product available without a doctor's prescription.
A variety of products claiming to prevent or treat osteoporosis have appeared in pharmacies and health
food stores in recent years. At present, ipriflavone is the only such product to have scientific evidence to
support its use.
How does ipriflavone work?
Ipriflavone slows down the work of the osteoclasts (bone-eroding cells). This allows the osteoblasts
(bone-building cells) to work more effectively.
How effective is it?
Ipriflavone maintains bone density at the spine.
Who can take it?
Ipriflavone is an alternative to consider to prevent osteoporosis in postmenopausal women. It is not
used to treat osteoporosis.
How is it taken?
The daily dosage varies according to the formulation. See the product instructions.
Are there side effects?
Because there is inconclusive evidence about the long-term safety of ipriflavone, use should be
carefully monitored by a physician.
