When taking vitamin d supplements, is it recommended to also take calcium with it?

Maybe: Adequate calcium and vitamin d nutrition is important at any age, especially for children and the elderly. Vitamin d enhances absorption of calcium from the gut. If you are managing a specific vitamin d deficiency, you should maintain a daily total calcium intake of 1000 mg. Management of osteoporosis requires 1100-2000 total mg ca per day. (total intake implies dietary plus supplemental).
