Antioxidants Explained | How Your Body Fights Aging & Cellular Damage

🫐 Every second, your body is fighting an invisible battle.

As your cells produce energy, they also generate unstable molecules called free radicals. Left unchecked, these molecules can damage DNA, proteins, and cell membranes, contributing to aging and many chronic diseases. Fortunately, your body has an extraordinary antioxidant defense system designed to keep oxidative stress under control.

In this episode of the Longevity series, we explore the science of oxidation, free radicals, and antioxidants. You'll discover how your body's natural defenses work, why diet plays such an important role, and what current research says about supplements, whole foods, exercise, and healthy aging.

Whether you're interested in nutrition, longevity, fitness, or preventive health, this evidence-based guide will help you understand one of the body's most important protective systems.
