(Ca2) as low levels. In addition, vitamin D and
calcium cooperation can affect on several types of immune cells like
antigen-presenting, (T) and (B) cells to adjust both adaptive and innate
immune responses, that may extend further than calcium and bone
homeostasis.[34].
Therefore, vitamins and minerals as principal nutrients for
immunonutrition might be useful for COVID-19 prevention.
