What are Free Radicals?

Here is the definition of Free Radicals:

an atom or group of atoms with at least one unpaired electron: in the body it is usually an oxygen molecule that has lost an electron and will stabilize itself by stealing an electron from a nearby molecule.

Scientists have proven that free radicals are the reasons of at least 70 different kinds of diseases, and that includes heart diseases and cancer, and they can expedites aging.



Here is an illustration. Cut an apple in half. It will begin to turn brown. If you look at it, when air hit that apple, the oxidized process begins, and aging and decaying will begin. If you can open up inside of your body, and look at it, you can actually see free radicals damage happening on a daily basis from the chemicals, and the stress, and the metabolic toxins. 

There are different types of free radicals:

• Reactive oxygen species, ROS or Oxygen free radicals
• Reactive nitrogen species RNS,  or Nitrogen free radicals

How free radicals are generated?

• metabolic toxins of our body
• over exercise
