    By eating food that contains vitamin D.

    The way I’ve heard it explained is that vitamin D is stored in our fat and is slow released over the winter months. Plus, there’s a lot of vitamin D in fish. Eat more fish.

    Aside from just supplementing through pills/foods, they have UVB lights for light therapy that help the body produce vitamin D.

    Stockpiling the D during the summer months, like mammals store fat for hibernating

    Blubber from marine mammals is exceptionally high in vitamin d

    Interestingly darker skinned people are more prone to this deficiency because the melanin in their skin and eyes is designed to block UV. My partner found this out when she moved from Indonesia to Australia in winter. Some Vit D tablets and a change in diet fixed that.

    Because people living in such places often obtain vitamin D through their diet by consuming vitamin D-rich foods, such as fatty fish, liver, and fortified dairy products. In addition, some people take vitamin D supplements to ensure that they maintain adequate levels, although it is much better to consume or produce vitamin D naturally anyway, as supplements will not nourish you as much as the sun can, the sun is life.

    Supplements help. If you eat fish with lots of omega 3 fatty acid, you have to be careful of Supplements.

    When working in Antarctica our vitamin d levels would get crazy low if we didn’t take supplements.

    Less melanin in their skins, more efficient production of vitamin d than dark skinned Southrons.

    They absorb needed Vitamin D thru diet. Here’s a fun fact for you tho…Redheads lack a pigment called eumelanin. Because of this, minimal amounts of UV rays can react with the 7-D in their skin that produces vitamin D. It is even theorized that the MC1R gene (ginger gene) evolved due to those environments. This is why redheads can still thrive with little direct sunlight…. and simultaneously, why we do so poorly in places with too much sunlight.

    Here in finland milk produce has added vitamin d in it for this reason. I get enough vitamin d simply from the amount of milk i consume.

    Supplements are also common.

    Dietary vitamin D (sourced from milk, fish, etc.)

    Lived in Fort McMurray, Alberta for 3 years.

    Certainly saw enough of it being bright out at 5am and still light out at 11pm, as well as not seeing the sun until 11am and it being dark out again at 4pm. I had blackout curtains to deal with the summer’s.

    Supplemented C, D, and Zinc. You can only eat so much fish.

    Winter greens are the highest in vitamin D oddly enough too.
