ROS are oxygen-containing molecules that can damage cells when present in excess.
Highly unstable molecules containing oxygen atoms with unpaired electrons, including free radicals and non-radical ROS. ROS are byproducts of cellular metabolism and environmental exposure.
Reactive oxygen species (ROS) encompass both free radicals and other highly reactive molecules derived from oxygen. ROS are generated endogenously through mitochondrial respiration, immune responses, and enzymatic reactions, as well as exogenously from environmental sources like smoking and radiation. While low levels of ROS serve important signaling functions in cell division and immune defense, excessive ROS accumulation causes widespread cellular damage. The body maintains ROS homeostasis through enzymatic and non-enzymatic antioxidant systems.
Acts as both beneficial signaling molecules at low levels and harmful oxidizing agents at elevated concentrations.
Balance antioxidant intake with varied whole foods rather than supplements. Maintain regular exercise and adequate sleep to support natural ROS regulation.
ROS require balanced management through both endogenous and dietary antioxidant systems.
