The Essential Role of Vitamins in Boosting Immunity

We all want strong immunity, especially in times when infections spread quickly. One of the easiest and most natural ways to support your immune system is through vitamins. Your body needs a variety of vitamins to function at its best and defend against illness.

According to PubMed Central, vitamins like C, D, and E are essential for immune defense. Without these nutrients, the body becomes more vulnerable to viruses and inflammation.
