Optimal Vitamin D Status

08/06/2021

Vitamin D has certainly gained a lot of attention over the last few years, especially with the introduction of covid-19 infections. Vitamin D plays an important role in immune system regulation, bone and calcium regulation as well as affecting mood disorders such as major depression and seasonal affective disorder (SAD). 

Vitamin D - How much do we need?

Vitamin D is a fat soluble vitamin, meaning it can build up in our system over time and is stored in our fat cells. It also means that it takes time to build up, and that it can be toxic in large amounts when taken as a supplement. Compared to water soluble vitamins, you will not urinate excess out. It is something to be aware of not taking too much. With that said, as a naturopathic doctor, my dosage might be a bit different than what conventional guidelines recommend. I also have different reference ranges when assessing laboratory values for optimal levels, versus simply deficient or not.
