Vitamin D could very well be one of the most important nutrients for your immune system.
Now that we are heading into cold and flu season (and a possible second wave of the pandemic) Vitamin D should be on everyone's radar for supplementation.
But how do you know how much to take?
Vitamin D is a fat soluble vitamin. This means you can store it up in your body. So the possibility of reaching a toxic level if you take too much is more likely than with a water soluble vitamin (like Vitamin C).
You also want to make sure that you are not Vitamin D deficient. If are deficient, or even suboptimal, you are putting yourself at risk for heart disease and poor immune function. Both of which are risk factors for poor outcomes with COVID-19.
Here are a couple studies that support this:
So back to the question, how do you know how much to take?
To optimize your dose you need to have a blood test.
This test is often not recommended by family physicians because OHIP does not pay for it.
I disagree with the common recommendation to just take the standard recommended dose. This is not personalized medicine.
8 out 10 patients that we test at our clinic come back either deficient or suboptimal. And this includes people who are already taking vitamin D and/or spend a lot of "time in the sun".
If you are interested in having your blood tested and you are already a patient at the clinic feel free to give us a call.

I have included an excellent video from Med Cram on the importance of vitamin D and the coronavirus.
Now I would love to hear from you! Do you know your vitamin D level? Why or why not? Leave a comment below and I'll be back next week with another edition of Doctor At Teacher Tuesday!
