produces unstable
oxygen molecules called

free radicals, the sometimes - toxic molecules
produced by our bodies as we process
oxygen, are the culprit behind aging.

free radicals and reactive
oxygen species
produced caused significant damage to the thyroid and reduced thyroid hormone production.

oxygen - based energy factories inside most of our cells) where it provides protection against damage from the
free radicals produced during energy production.
So, not only does the human body have difficulty metabolizing them, but these F&O's tend to

produces free radicals and reactive
oxygen species that can damage cellular membranes and even oxidize LDL cholesterol.
When the mitochondria are working to
produce energy, some electrons leak from the electron transport chain to react with
oxygen and form the
free radical superoxide.
But the process of
producing ATP creates a huge burst of damaging
free radicals known as reactive
oxygen species (ROS), which are the chief cause of mitochondria destruction.

free radicals and reactive
oxygen species
produced from lipid peroxidation.

oxygen, they naturally
produce «
free radicals» (by - products) which cause damage to our DNA, cell membranes and cellular organelles.
