Recent news shows an association between covid-19 hospitalizations and Vitamin D levels.  While having low vitamin D may not cause covid-19 complications research shows a correlation between adequate Vitamin D levels and a less severe response.  

1.  Spend time in the sun! In addition to promoting Vitamin D production, sun exposure during the day can help your sleep by regulating your circadian rhythms. Getting enough sunlight is as important as reducing exposure to artificial lights near bedtime.  2.   Eat foods rich in Vitamin D such as egg yolks, fatty fish (salmon, sardines, anchovies and mackerel, and mushrooms. Tuna is also a rich source but eat limited amounts due to heavy metal contamination.  3.  If you do not eat animal products, eat plenty of mushrooms and look for Vitamin D fortified foods like non-dairy milks, cereals, and others.  4.  Have your Vitamin D levels checked through a blood test. Vitamin D is fat soluble so it accumulates in our tissues; thus it can become to high with over supplementation. Ask your provider to check your levels to get the most accurate feedback about how much to supplement if you are low.  5. If your blood levels are low, use Vitamin D3 to supplement; it is more bioavailable.   PS - Healthy Vitamin D levels also regulate inflammation, mineralization of bones, and calcium absorption!
