Vitamins A, C, and E support immune health through their antioxidant properties, helping to neutralize free radicals and reduce oxidative stress. Vitamin A is crucial for maintaining the integrity of mucosal barriers and is vital for immune function. Vitamin C enhances the production of white blood cells and supports skin health. Vitamin E protects cell membranes from oxidative damage, contributing to overall immune efficiency. Together, these vitamins play essential roles in supporting the body's defense mechanisms, promoting resilience against infections and improving overall health.
