RDA for Calcium. According to the Institute of Medicine, the recommended dietary allowance for calcium for healthy males between the ages of 19 and 70 years is 1,000 milligrams per day. The recommendations increase to 1,200 milligrams for males after age 70. Vitamin D is also essential for absorption of calcium, and the RDA for vitamin D for men between ages 19 and 70 is approximately 600 IU per day and 800 units per day over age 70.
Calcium needs per day for men are quite similar to the requirements of their female counterparts. Those who are between 19 and 70 years of age, 1000 milligrams of calcium per day would suffice for them, whereas this amount would go up to 1200 milligrams every day if the male is beyond 70 years of age.
