B) As a byproduct of normal metabolic processes generating reactive oxygen species

**Why the Body’s Natural Process Creates Reactive Oxygen Species – Science and everyday meaning** In a quiet corner of human biology, a natural process unfolds after every breath: chemical energy release in cells generates reactive oxygen species. These molecules, vital to cellular function, emerge as a natural byproduct of metabolism—without which life as we know it would be impossible. For years, their role has drawn scientific attention, but rising awareness in the U.S. now reflects a deeper curiosity about what these molecules mean for health, aging, and daily well-being. **Why Reactive Oxygen Species Matter in Modern Health Conversations** As awareness of cellular health grows, so does interest in reactive oxygen species—known scientifically as ROS. These molecules form during oxygen metabolism in mitochondria and play essential roles in signaling, immunity, and energy regulation. While elevated levels are linked to stress and cellular damage, at balanced levels they support vital biological functions. Understanding how and why ROS naturally develop in the body is now part of a broader conversation about preventive health, antioxidant balance, and long-term vitality.
