PrintWhat are Antioxidants?
Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, unstable molecules that the body produces as a reaction to environmental and other pressures.
There are thought to be hundreds and possibly thousands of substances that can act as antioxidants. Each has its own role and can interact with others to help the body work effectively.
“Antioxidant” is not really the name of a substance, but rather it describes what a range of substances can do.
