precise mechanism of action of fish oil [omega-3-fatty acid] in amelioration postmenopausal osteoporosis in female rats

ABSTRACT

This work studied the mechanism of the action of fish oil rich in eicosapentaenoic acid [EPA] and docasahexaenoic acid [DHA] [omega-3 fatty acid] on postmenopausal symptoms and bone resorption in intact and ovariectomized [ovx] female rats. The effects of dietary supplementation of fish oil [omega-3 fatty acid] for eight weeks on hypothalamic-pituitary-gonadal axis, bone formation markers, bone resorption markers and bone mineral metabolism were tested. It was concluded that the resulted data could be the protective mechanisms of fish oil against postmenopausal osteoporosis. These mechanisms based on promote positive calcium balance, increase osteoblastic bone formation and decreased bone resorption
