Vitamin D and COVID-19
Low Vitamin D levels have been linked to increased risk of:
developing severe illness with COVID-19
dying from COVID-19
People are more likely to be Vitamin D deficient in the winter. Also, those with dark skin are more likely to be Vitamin D deficient because darker skin creates less Vitamin D through sun exposure.
You can boost your vitamin D level through Vitamin D3 supplements, sun exposure on your skin, and foods such as organ meats, with smaller quantities in clams, salmon, and egg yolks.
