A strong immune system is crucial for protecting your body against infections, illnesses, and diseases. One of the best ways to enhance your immunity is by ensuring you get the right vitamins. Vitamins play a key role in supporting immune functions, reducing inflammation, and strengthening your body's natural defenses. In this article, we will explore 5 vitamins that are best for boosting your immunity and helping your body fight infections effectively.
1. Vitamin C – The Ultimate Immunity Booster
Vitamin C, also known as ascorbic acid, is one of the most well-known immunity-boosting vitamins. It is a powerful antioxidant that helps protect cells from damage, supports the production of white blood cells, and enhances the skin's defense system.

Since our body does not produce or store vitamin C, it is essential to consume it daily through diet or supplements.
