A fairly recent herbal product called chrysin, which is extracted from a Passiflora species, is making news, especially for men. Chrysin stops the conversion of testosterone to estradiol, the most potent estrogen. This is important because testosterone levels are maintained, which keeps bones and muscles strong, but also too much estradiol in a man may lead to an increased risk for prostate cancer. More research in this area is being done. It can be seen that there is more to maintaining healthy, strong bones than just taking calcium.
Bones are one of the most dynamic tissues in the body.
They constantly remodel themselves in answer to the amount of stress they undergo. If important nutrients are missing or hormones aren t communicating properly, bones become weak and brittle. Fortunately this can be corrected. Gaby, Alan R., Preventing and Reversing Osteoporosis , Prima Publishing, 1994. Prior, C., Progesterone as a Bone-Trophic Hormone, Endocr.
