Most people are vitamin D deficient. Particularly during the winter, when covid, flu, pneumonia, etc are most prevalent.
Sounds like a bunch of horseshit to me.
-Just over two-thirds of Canadians (68%) had blood concentrations of vitamin D over 50 nmol/L—a level that is sufficient for healthy bones for most people. About 32% of Canadians were below the cut-off.
-Children aged 3 to 5 had the highest rates above the cut-off (89%), while the 20- to 39-year-olds had the lowest (59%).
-About 40% of Canadians were below the cut-off in winter, compared with 25% in the summer.

And referencing some rando on YouTube is? LOL you're such a dumb twat.
