Vitamin D & Hydrogen Peroxide
A recent study [4] revealed that increasing the levels of vitamin D present in the serum can lower the risk of developing ear infections. Vitamin D is important for boosting immune function. This may explain why consuming the vitamin through natural foods and supplements are effective in reducing susceptibility to ear infections.
Dilute hydrogen peroxide is a mild disinfectant that can be used to prevent bacterial infection in the ear. Insert a small swab with hydrogen peroxide into the ear canal. The quantity of hydrogen peroxide should be very little so it doesn’t end up causing problems.
