About Vitamin D

- Source: It is naturally present in a few foods (like fatty fish (salmon, tuna), fortified milk, and eggs) and available as a dietary supplement.
- It is also produced endogenously when ultraviolet (UV) rays from sunlight strike the skin and trigger vitamin D synthesis.
Deficiency
- Vitamin D deficiency can lead to weakened bones (osteoporosis in adults, rickets in children), hypocalcemia (low calcium levels in your blood) which leads to secondary hyperparathyroidism (overactive parathyroid glands attempting to keep blood calcium levels normal).
Significance

- It plays a crucial role in regulating calcium and phosphate levels, which are necessary for strong bones and teeth.
- Vitamin D also helps regulate the function of immune cells and can influence muscle and nerve function.
