During the dreary days of winter, many turn to supplements to up their vitamin D intake.
But according to a new study, the dose of vitamin D one gets from a supplement may greatly vary from what is listed on the label.
The Journal of the American Medical Association tested vitamin D pills sold in the United States and found they contained from nine to 140 per cent of the dosage listed on the label.
The discrepancy is not dangerous, but some contained too little vitamin D to treat someone with a deficiency.
The Canadian recommended daily dosage for adults is 2000 units per day.
