Good question. The requirement of vitamin D increases with age. For age 70 plus years, the daily recommended intake of vitamin D is 800 IU (or 20 mcg). For all other ages except for infants, the daily recommended dose is 600 IU. This includes all the vitamin intake from regular diet as well as supplements. The requirement is same for both males and females. Anything more is associated with risk of kidney stones. Although anything below 4000IU/day of vitamin D is considered safe or tolerable, but the recommended dose in supplements is 800 IU.

As for calcium, its requirement are 1200 mg/day for ages 70 plus. For ages 19 - 50, the requirement is 1000 mg/day.

So if you are taking 800 IU of vitamin D and 1000 mg of calcium, your intakes are good. Although you can increase the calcium to 1200 if desired.
