Vitamin C is a vital nutrient that plays a significant role in supporting the immune system. Here’s how it contributes to immune health:

🛡️ How Vitamin C Enhances Immunity

Boosts White Blood Cell Function Vitamin C stimulates the production and enhances the function of white blood cells, such as lymphocytes and phagocytes, which are essential for defending the body against infections. 

Strengthens Skin Defenses As an antioxidant, vitamin C is actively transported to the skin, where it helps maintain the skin’s barrier function, providing a first line of defense against pathogens. 

Reduces Inflammation Vitamin C has anti-inflammatory properties that can help lower levels of pro-inflammatory compounds, aiding in tissue healing and recovery from infections.

Enhances Antibody Production Adequate vitamin C levels are associated with increased production of antibodies, which are crucial for identifying and neutralizing harmful invaders. 

Supports Neutrophil Function Neutrophils, key players in the immune response, rely on vitamin C to perform effectively. Supplementation has been shown to improve their ability to combat infections.
