Many who end up with severe COVID-19 have reduced adaptive immune function. As a result, they don’t clear the virus quickly and end up having to rely on a more proinflammatory killing of the virus inside their cells instead, which damages healthy cells as well

Reduced T cell function appears to be a primary cause of severe COVID-19

Diet and nutritional supplementation are two key strategies that can help support your immune function. Topping the list of nutrients required are vitamin D, magnesium, zinc and selenium

Melatonin is also important. It has the ability to freely pass into any cell where it upregulates Nrf2 transcription, thereby boosting endogenous antioxidant production

Other strategies that help support your immunity through a variety of means include time-restricted eating, exercise and sauna
