Curcumin, an extract from turmeric, has can be used to combat osteoporosis. Curcumin has been extensively researched for cancer prevention, improving immune function, heart protection, and anti-inflammatroy effects. A recent study may add bone-health to the list of reaseons to supplement with curcumin. The study involved removing the ovaries form female rats. This produces hormonal changes similar to those in post-menopausal women--specifically, estrogen production drops off. Since estrogen is necessary for bone health, the rats developed osteoporosis. The researchers then tried supplementing a similar group of rats with curcumin, and their bone density increased! They concluded "Curcumin produces beneficial changes in bone turnover and increases in bone strength using the ovariectomized mature rat model of postmenopausal osteoporosis."
Please visit my Osteoporosis Page for more information on how to build bone health holistically! Also note that in my store I have a product that combines the bone building effects of whey protein with curcumin. I highly recommend it for bone health.
