Taking Vitamin D & Vitamin C (at least 500mg/day) regularly can help prevent frequent viral infections. My husband used to get ear infections & colds constantly. Then I started giving him 1000mg/day Vitamin C and a calcium supplement that included Vitamin D, and he has not had an ear infection in a few years, and he seems to avoid catching most colds now.
Be sure to check with your doctor about these supplements to make sure they are safe for you before you take them.
