Vitamin D and calcium are important nutrients that play a crucial role in keeping the bones healthy. The Endocrine Society and the Institute of Medicine recommends certain consumption levels based on age and health.

The Bone Health & Osteoporosis Foundation maintains that it is equally important to continue getting enough calcium and vitamin D to prevent further bone loss if you are prescribed a medication to prevent bone loss or fractures. If you are not able to get enough vitamin D and calcium from diet alone, doctors often prescribe supplements to increase your intake.

However it is important to highlight that too much calcium or vitamin D can lead to heart and kidney problems.
