Why is vitamin D important to take with vitamin C?
In order to absorb calcium effectively, your body needs vitamin D as well.
One of the best sources of vitamin D is sunshine. When exposed to the sun, your skin naturally produces vitamin D. However, keep in mind that excessive sun exposure without sunscreen protection may increase the risk of skin cancer and early aging.
You can also obtain vitamin D through foods such as mushrooms, salmon, and egg yolk, as well as vitamin D supplements.
Why is getting enough calcium important?
Calcium plays an important role in maintaining the health of your body. Some of the most important functions of calcium include:
- Bone health: Calcium is required for the growth, development and maintenance of bones. For growing children, calcium aids in bone development; for adults, calcium maintains bone density and slows down bone loss that comes with aging. Women going through menopause are especially prone to bone density loss and have a high risk of developing osteoporosis due to the decline of the hormone estrogen
- Muscle health: Calcium plays an important role in muscle health. When a nerve stimulates a muscle, calcium is released, which helps the protein carry out the act of muscle contraction, causing movement. Calcium gets pumped out of the muscle as well to help it relax.
- Cardiovascular health: Calcium aids the blood clotting process and helps maintain the functions of the heart muscles. It helps in the relaxation of the smooth muscles that surround the blood vessels.
The daily recommended dietary allowance of calcium for both men and women is 1000 mg. However, menopausal women are recommended to consume 1200 mg of calcium a day. Pregnant women have higher calcium needs.
What happens if you have a calcium deficiency?

- Osteopenia
