Except for calcium, vitamin D is a very essential nutrient for our bones. Not just this, it also plays a vital role in aiding in the absorption of calcium as well as phosphate into the bones. Therefore, making our bones stronger. In the human body, it exists in two forms, e.g., Vitamin D2 and Vitamin D3. Its deficiency can result in brittle, soft, and weak bones, moreover, in adults, this deficiency can result in osteoporosis. Various researches show that vitamin D and rheumatoid arthritis (RA) are linked. RA is a joint-related autoimmune disorder that causes, numbness, swelling, tingling, and joint pain. To support bone and joint health, calcium and vitamin D work together. When exposed to sunlight, the human body can produce its own vitamin D. It is also essential for various other things except for bone health, which includes:

  • Muscle Function
  • Brain Development
  • Immune function

Along with that, vitamins can also help manage several medical conditions like RA, Type 1 diabetes, and Multiple Sclerosis (MS). The most commonly affected areas by vitamin D deficiency include the lower back, pelvis, and hips.

There are various sources of consuming vitamin D, it can be consumed orally or via sunshine. This is then converted into active form which then promotes calcium absorption.

3. Collaboration with parathyroid gland:

Parathyroid glands keep the calcium levels at a normal or optimal range in the blood. These glands are continuously communicating with the skeleton, kidney, and gut. This is why there should be a sufficient amount of calcium and vitamin D so the calcium can be put to good use and absorbed. However, due to their insufficient intake, parathyroid glands borrow calcium from the skeleton to maintain an optimal range in the blood.
