Exposure to the sun during winter is insufficient to maintain a good level of vitamin D
It's a myth!
With their harsh climate, Quebecers are at risk of suffering from a vitamin D deficiency from October to April – more than half the year!
During this period, sunlight is totally ineffective at synthesizing vitamin D, whereas in the summer, even brief exposure can significantly increase the body’s reserves of this vitamin.
In winter, your doctor could prescribe a dose of vitamin D (blood sample) and still notice a deficiency. To make up the difference, eating foods rich in vitamin D (such as salmon, cod or other fatty fish) may be helpful, but supplements remain the best way to reach adequate levels.
