                                In the human body, an estimated 1-2% of the oxygen we breathe is converted into reactive oxygen species (ROS) or free radicals, which cause cellular damage if left unchecked. To counter this, biological systems are equipped with a complex and sophisticated defense mechanism: antioxidants. These vital compounds are essential for neutralizing harmful free radicals and maintaining overall cellular health.
