One of the most popular vitamins known to help boost the immune system is Vitamin C. Found in citrus fruits, tomatoes, broccoli, and other veggies, Vitamin C contains antioxidants that help protect cells from oxidative stress and damage.
If you do catch the common cold or come down with the flu, Vitamin C may be able to help reduce the illness’ severity and duration. Vitamin C may also help improve heart health by supporting healthy cholesterol levels.
