3 Best Vitamins To Boost Immunity The food you eat determines your overall health and immunity. Immunity being our body’s first line of defense is much more needed now than ever. While a healthy balanced diet and lifestyle is the need of the hour, few nutrients play a very special role when it comes to boosting our immunity. Among different nutrients, today we will discuss the most potent vitamins to boost immunity. Essential Vitamins To Boost Immunity 1. Vitamin C Also known as ascorbic acid, Vitamin C is water-soluble. It helps kick start the action of our immune system by encouraging the production of lymphocytes & phagocytes, thus, helping the body protect itself from infections. The body cannot store this vitamin and being water-soluble, it’s easily lost through bodily fluids. Hence, it is important to consume foods rich in Vitamin C on a daily basis. Being heat sensitive, this vitamin is destroyed on heating, so it is better to get it from raw foods.
