How Much Calcium Should I Consume Each Day?

Calcium and Vitamin D are important nutrients that are critical to bone health. Without adequate calcium and Vitamin D, the body cannot maintain normal bone health and structure, and people who don't have adequate nutrients can be susceptible to bone problems including osteoporosis and fracture.

The following is the recommended dietary allowance (RDA) for calcium as published by National Academy of Sciences. While calcium and Vitamin D are not the only essential nutrients for proper bone health, they are two critical components, and often individuals lack adequate intake. The good news is that even if your diet does not provide adequate calcium, there are ways to supplement your intake. People should ensure they are taking adequate calcium in their diet, and if not, discuss with their physician or nutritionist how they can increase their intake.
