Understanding Calciferol
- Fat-soluble: This means vitamin D is stored in the body's fatty tissue and liver.
- Seco-sterols: These are steroid molecules with a broken ring structure.
Forms of Vitamin D
While the term calciferol refers to the broader group, there are two primary forms of vitamin D that are relevant:
- Vitamin D2 (ergocalciferol): This form is found in plants and is often used in supplements.
- Vitamin D3 (cholecalciferol): This form is produced in the skin when exposed to sunlight and is also found in animal products.
How Vitamin D Works
Vitamin D plays a critical role in:
- Calcium absorption: Helping the body absorb calcium from food, which is essential for bone health.
- Immune function: Supports a healthy immune system.
- Cell growth: Involved in cell growth and development.
Why Vitamin D is Important
Maintaining adequate vitamin D levels is crucial for overall health and can help prevent conditions like:
- Rickets (in children): Softening and weakening of bones due to lack of vitamin D.
- Osteomalacia (in adults): Weakening of bones, leading to bone pain and muscle weakness.
- Osteoporosis: Increased risk of bone fractures.
