Vitamin D

Why is Vitamin D so important?

What does Vitamin D do?

Vitamin D plays a huge role on maintaining homeostasis, it’s important in many of our bodily functions.

  • Vitamin D helps to strengthen our bones by helping to absorb and store calcium in our skeletal tissue.

  • Vitamin D helps our bodies recycle calcium in the kidneys so our bones are able to reabsorb it. This is important; as if it didn’t happen we would lose calcium when we urinate.

  • Vitamin D helps to active our genes that release dopamine and serotonin. Lacking these is commonly linked to depression.

Should I be supplementing Vitamin D?

Due to our main source of vitamin D being from sunlight, during the winter months it is recommended to be taking a supplement, as getting enough from our diet is very difficult. During the summer months, we should be able to get enough from sunlight. So the time of year really has a large role in whether supplementing is ‘needed’ or not. However, if you don’t get much sun exposure even in the summer months, a 10mcg supplement is still recommended


Too much vitamin D

Taking too much vitamin D over a prolonged period can cause calcium to build up in the body. This can actually begin to weaken the bones and puts your kidneys and heart at risk of damage.

A daily dose of 10mcg is considered safe and no more than 100mcg should be taken per day as these levels can become harmful. Vitamin D is extremely important; if you’re deficient always take your doctor’s advice on what dosage to be used.
