While vitamin D has extremely no abuse potential, and very rare side effects, the evidence from "The Big Vitamin D Mistake"
paper (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5541280/) clearly recommends a dosage of at least 8000IU daily for adults and seniors.
The effects of vitamin D shortage have disproportionate negative effect on population with dark skin tone, but is frequently offset by traditional Inuit diet.
Health Canada should consider recommending 8000IU vitamin D + vitamin K as daily prescriptions to all healthy adults. Fortification of milk with cholecalciferol has been effective in Finnland, so may also be considered.
I sent this to Health Canada email, in case they did not consider the consequences.
Apparently Bureau of Nutritional Sciences of Food Directorate is responsible for the norms in Canada. I resent the request to update recommendation there and asked whether they reconsidered the mentioned paper.
