Vitamin D is better~ Here's why:
- Vitamin D plays an important role in the maintenance of organ systems.
- Vitamin D regulates the calcium and phosphorus levels in the blood by promoting their absorption from food in the intestines, and by promoting re-absorption of calcium in the kidneys.
- It promotes bone formation and mineralization and is essential in the development of an intact and strong skeleton. However, at very high levels it will promote the resorption of bone.
- It inhibits parathyroid hormone secretion from the parathyroid gland.
- Vitamin D affects the immune system by promoting phagocytosis, anti-tumor activity, and immunomodulatory functions.
