In this blog, we will explore the benefits of calcium and vitamin D for health, daily requirements, top food sources, risks of deficiency, their relationship with other nutrients, and practical strategies to ensure you’re meeting your calcium and vitamin D needs.

The Benefits of Calcium and Vitamin D for Health 

Calcium and vitamin D offer an array of health benefits that extend beyond strong bones. Calcium is vital for supporting nerve transmission, regulating blood pressure, and ensuring blood clotting functions effectively. On the other hand, vitamin D plays a crucial role in calcium absorption, reducing inflammation, and promoting healthy cell growth. Here are some other health benefits of calcium & vitamin D: 

  • Bone health: Calcium is the main building block of bones, and vitamin D helps the body absorb calcium. Adequate intake of calcium and vitamin D can help to prevent osteoporosis, a condition that causes bones to become weak and brittle.
  • Muscle function: Calcium is also important for muscle function. It helps to keep muscles contracting and relaxing properly.
  • Immune system support: Vitamin D plays an important role in the immune system. It helps the body fight off infection and disease.
  • Other health benefits: Calcium and vitamin D may also be beneficial for other health conditions, such as high blood pressure, heart disease, and cancer.

How much calcium and vitamin D do I need each day?

The recommended daily intake (RDI) of calcium for adults is 1,000 milligrams (mg). The RDI for vitamin D is 600 international units (IU) for adults under age 70 and 800 IU for adults over age 70.
