Daily calcium intake above 2,000 mg is not likely to provide additional benefit. Adequate calcium intake is also linked to reduced osteoporosis by reducing bone loss in older men and women.

Vitamin D is essential for intestinal calcium and phosphorous absorption. Ergocalciferol is a vegetarian form of Vitamin D.
