Here are our top picks that should be in everyone’s daily routine to improve immune function and lots more.

Vitamin D

As an immunomodulator targeting various immune cells, including monocytes, macrophages, dendritic cells (DCs), as well as T-lymphocytes and B-lymphocytes, we find vitamin D modulating both innate and adaptive immune responses. Besides being targets, immune cells express vitamin D-activating enzymes, allowing local conversion of inactive vitamin D into active vitamin D within the immune system.  In short vitamin D enhances the pathogen fighting ability of immune cells and lowers inflammation.  With adequate levels in the body we see stronger immune function and lower risk of infection.

Zinc

Zinc also plays a role in reducing inflammation.  There have been many studies linking supplementation of zinc to protecting against upper respiratory tract infections like the common cold.  It has also been linked to preventing pneumonia.  Deficiency in zinc leads to lowered immune function and higher risk of infection.

Vitamin C

The go to supplement for many who are trying to fight off infections, vitamin C most certainly plays a very important role in immune function.  It is integral to keeping the immune system healthy.  It is a strong antioxidant removing free radicals that cause oxidative stress. This nutrient has been a common treatment for the common cold for decades or more and has been shown to reduce the duration and severity of respiratory infections.
