Spread calcium across the day, and count the calcium in your food
National Institutes of Health (NIH) says absorption from supplements is highest at doses of 500 mg or less. The labels say up to 2 a day, so take one with each of two meals; two a day gives you two doses. Adults 19 to 50 and men 51 to 70 need 1,000 mg of calcium a day from food and supplements together; women 51 to 70 and everyone over 70 need 1,200 mg. More in our calcium dosage guide.
NIH puts the adult upper limit for calcium at 2,000 to 2,500 mg a day, food and supplements together.
Most adults need 600 IU of vitamin D a day, and 800 IU over 70
