ROS (reactive oxygen species)

Reactive oxygen species (ROS) are highly reactive molecules containing oxygen. They are naturally produced in our bodies during cell processes like energy production. While small amounts of ROS play important roles in cell signaling and immune responses, excessive ROS can damage cells, proteins, and DNA, leading to aging and diseases such as cancer and heart conditions. The body has antioxidant defenses to balance ROS levels and prevent harm. Overall, ROS are a normal part of biological function, but maintaining their balance is crucial for health.
