Why do I need vitamin D?
Vitamins are substances that your body needs to grow and develop normally. Vitamin D is important to your body because:
- It helps your body absorb calcium. Calcium is one of the main building blocks of bone. A lack of vitamin D can lead to bone diseases such as osteoporosis or rickets.
- It also has a role in your nerve, muscle, and immune systems:
- Your muscles need it to move
- Your nerves need it to carry messages between your brain and your body
- Your immune system needs vitamin D to fight off bacteria and viruses
How do I get vitamin D?
You can get vitamin D in three ways: through your skin, from your diet, and from supplements. Your body forms vitamin D naturally after exposure to sunlight. However, too much sun exposure can lead to skin aging and skin cancer. So many people try to get their vitamin D from other sources.
