How Antioxidants Work
The Role of Free Radicals
Free radicals are highly reactive molecules with unpaired electrons. They are produced naturally during metabolic processes in the body, such as when cells use oxygen to generate energy. However, external factors like pollution, smoking, and radiation can also increase free radical production. These molecules seek out and damage nearby cells by stealing electrons, leading to a chain reaction of oxidative damage.
This oxidative stress can harm cells, proteins, and DNA, contributing to aging and the development of chronic diseases. Free radicals are involved in inflammatory processes and can disrupt normal cell function, making it essential to manage their levels through antioxidant protection.
How Antioxidants Neutralize Free Radicals
