Which vitamin is known for its role in immunity and heart health?

Vitamin E is known for its role in immunity and heart health due to its powerful antioxidant properties. Antioxidants help protect cells from damage caused by free radicals, which can contribute to chronic diseases, including heart disease. Specifically, Vitamin E is involved in immune function by enhancing the body's immune response, making it important for overall health and the prevention of infections.

In terms of heart health, Vitamin E supports the integrity of cell membranes and may help prevent the oxidation of low-density lipoprotein (LDL) cholesterol, which is a risk factor for atherosclerosis and heart disease. By protecting the cardiovascular system and bolstering the immune system, Vitamin E plays a critical role in maintaining overall health.

The other vitamins mentioned each serve important roles in the body, but they do not specifically highlight the dual focus on immunity and heart health like Vitamin E does. For instance, Vitamin A is primarily recognized for its role in vision and skin health, Vitamin D is crucial for calcium metabolism and bone health, and Vitamin K is essential for blood clotting and bone health.
