Ipriflavone

  • What Is It?

    • Ipriflavone is a synthetic isoflavone, used to prevent bone resorption, maintain bone density, and manage osteoporosis.

  • How Does It Work in the Body?

    • Ipriflavone works by inhibiting calcium-dependent protease throughout the body [49].

  • What Is It Used for?

    • There is evidence that ipriflavone (in conjunction with estrogen and/or calcium) may strengthen bones in postmenopausal women with osteoporosis.

  • Precautions/Side Effects:

    • Per a systematic review by Hu et al., mild gastrointestinal symptoms were noted. Additionally, a mild decrease in lymphocyte count was observed but resolved with discontinuation of ipriflavone.

  • Evidence for and Against:

    • According to Hu et al., ipriflavone significantly increases bone mineral density and has inhibitory effects on bone resorption markers in postmenopausal women with osteopenia or osteoporosis.

    • Several studies have shown that genistein and ipriflavone have beneficial effects on bone density and are safe in postmenopausal women. This may be considered as a complementary or alternative option in the prevention and treatment of menopause-related osteoporosis.  


  • Dosage:

    • Osteoporosis: 200 mg of ipriflavone by mouth, three times daily.

    • Paget disease: 600–1200 mg of ipriflavone by mouth, daily.

  • Interactions:

    • Ipriflavone is contraindicated in individuals with an existing history of hypersensitivity to any of its ingredients (Ipriflavone, Hypromellose, Leucine, or Magnesium Citrate).
