With a meal. Food helps with absorption, especially for calcium carbonate.
Better not to. Your body can only absorb about 500mg of calcium at a time. Split your dose if you're taking more than that.

Extensive research supports the benefits of calcium and vitamin D for bone health, particularly in preventing osteoporosis and fractures. Vitamin D's role in enhancing calcium absorption is well-established.
Calcium is mined from the earth as limestone or oyster shells. · Vitamin D3 is typically derived from lanolin, the oil in sheep's wool, after UV exposure.
