50-year-old women generally enter menopause, which is a sign of aging, and the level of estrogen will drop, which will have a serious impact on osteoporosis. Patients can eat more calcium tablets, calcium carbonate and calcium gluconate. Pay attention to getting more sunshine while taking calcium, because the absorption of calcium requires vitamin D. At ordinary times, vitamin D exists under the skin as inactive calcitol, which can only be activated by ultraviolet irradiation, and then it is hydroxylated twice by liver and kidney to form 1, 25- dihydroxyvitamin D3, which can help the intestinal calcium absorption. Women around the age of 50 can eat calcium tablets and drink milk, mainly to strengthen the intake of active vitamin D. Only when active vitamin D is sufficient can calcium be absorbed well.
