Vitamin D and your Immune system

"The benefits of taking Vitamin D supplements are well documented."

I’ve been taking 4000iu a day for a couple of years. I typically don’t take any when I can get sufficient doses through exposure from sunlight (when the sun is 30 degrees or more above the horizon). There are papers that state you ‘may’ get VDT(Vitamin D Toxicity) through mega doses of Vitamin D (1). Other research infers that VDT is rare, happening only if the person gets massive doses, “Vitamin D intoxication associated with hypercalcemia, hyperphosphatemia, and suppressed parathyroid hormone level is typically seen in patients who are receiving massive doses of vitamin D in the range of 50,000 to 1 million IU/d for several months to years” (2).

The benefits of taking Vitamin D supplements are well documented. There is strong evidence showing Vitamin D supports the immune system (3). If you are deficient in Vitamin D, the rate at which you may experience major complications with a COVID-19 infection is higher than people who have adequate levels of Vitamin D (4).

So, are you supplementing with Vitamin D?
