Vitamin deficiencies linked to respiratory conditions, including COVID-19:
Oct. 27 (UPI) -- Increasing vitamins A, E and D through diet changes or supplements reduces a person's risk for breathing and respiratory conditions, including flu and COVID-19, a study published Tuesday by the journal BMJ Nutrition Prevention & Health found.
People who consumed recommended amounts of the three key nutrients were less likely to develop the flu, colds, chronic obstructive pulmonary disease and asthma, the data showed.
Research has linked vitamin D, in particular, with boosting immune system function, and being deficient in the nutrient has been found to increase a person's risk for severe COVID-19.
Vitamins A, E and D -- as well as vitamin C -- are all considered micronutrients, meaning they are needed in relatively small doses to live.
[...] Major dietary sources of vitamin A include liver, whole milk and cheese, as well as carrots, dark green leafy vegetables and orange-colored fruits, while vegetable oils, nuts and seeds are primary sources of vitamin E.
Adequate intake of vitamin D through diet is more difficult to achieve, given that it is not found naturally in most foods, though it can be acquired by spending time in the sun. But people often take supplements to ensure adequate levels of the vitamin, the researchers said.

Not necessarily. Maybe for you white boys who live in the south. People with dark skin it works in equatorial regions, but not so well in regions north (or south) of there. We're getting into a season where people who have 9-5 jobs may only see the sun on weekends. Hell, a bit further north there's a winter period when there's not much sun except around noon, and it's at a low angle. And you don't voluntarily exposed more than a few square inches of skin to the weather for long, even if this thing you call "sun" exists.

Winter's winter all over the place (except tropical places but they're just showing off so fuck them). Everyone ends up short on D when it's just too damned cold to run around in shorts.
My rights don't end where your fear begins.

Vitamin D is stored in fat and tends to stick around for a long time. The half life in the body varies by a lot, but it may be six weeks in good conditions. At high latitudes, if people manage to accumulate plenty of vitamin D when the weather allows, many will not develop deficiency during the winter.
Keep in mind that people at extreme latitudes, e.g. Eskimos, tend to have a diet high in vitamin D - rich fatty foods.
