What is Vitamin D?
Vitamin D is a fat-soluble vitamin that your body does not produce on its own. That means you need to obtain vitamin D through external sources, such as your diet or supplementation.
Vitamin D plays a role in many of your body’s systems such as your cell growth and development, immune function, cardiovascular health, metabolism, inflammation regulation, and more.
Most people can get enough vitamin D through exposure to sunlight. However, with many people spending most of their time indoors due to work or school, it isn’t always possible to get the exposure you need in order for your body to convert enough vitamin D for normal function.
Vitamin D deficiency can influence your:
- Circulatory system
- Mood
- Energy levels
- Metabolism
- Bone health
- Respiratory system
- Muscle aches and weakness
A deficiency in vitamin D can lead to frequent short-term illnesses and long-term chronic diseases, which is why it’s important to correct a deficiency as soon as possible.
