What is Antioxidant?

The antioxidant is for preventing oxidation, and also to remove Reactive oxygen species (ROS).


What is oxidation?

Oxidation means the chemical reaction when a body meets oxygen.

Most of the materials near us get oxidation, for example, food, DNA, cells, metals, and so on.

When we breathe, oxygen comes into the body, and then the body will use the oxygen for chemical reactions for Metabolism. After using oxygen, sometimes a few small pieces of oxygen left after the chemical reaction. The left pieces of oxygen in the body are Reactive oxygen species (ROS).
ROS is the main key.

ROS is also called bad oxygen. It increases the speed of oxidation in the body which could give damage to the structure of cells, functions of cells, and DNA.

In the body, ROS could oxidate amino acid. It means decreasing functions of protein, making mutation, being reasons for many diseases.

Some facts , smoking, drinking, overeating,  could lead oxidation to faster.

Oxidation is not good.  But!! Some ROS are necessary for the human body. 
A small amount of ROS is necessary. If we have no ROS in a body, the body will get slow metabolism.  All the physiological phenomenon will be slow and decreased.
That is why we need some. The matter is that it is hard to keep a small amount.





Then, if we get oxidation, what is going to happen?

1. Being decayed and decomposed 
 : You can see that if you leave apple outside for a while, the apple will be getting dark.
 This reaction is caused by oxidation.  The apple meets oxygen then cells in apple get a reaction with oxygen.


2.  Aging is the same meaning as oxidation
: Aging is the same as oxidation. For example, if apple is outside for a long time, the apple will be getting dark. When our body and skin meet oxygen, then oxidation happens to us.  Skin will be
dry, loose, and wrinkle.


3. Bad effect to cells and DNA
: Oxidation can lead to making mutation of cells, damage to the structure of cells, and damage to DNA.


4. Decreasing of functions of protein
: If protein in a body gets oxidation, the quality of protein will be decreased.
Protein does much stuff in the body, but oxidation makes it slow and worse.


5. There is a study that more than 80% of disease is caused by oxidation
: The study shows us that more than 80% of disease these days in the world is caused by
oxidation. The diseases are include 'cancer, diabetes, arteriosclerosis, stroke, nephritis, and hepatitis.





What is the antioxidant material?

• Vitamin A : Many material belong to vitamin A, but for antioxidants, important thing is PRO VITAMIN A which is Carotenoids. 

• Vitamin C

• Vitamin E

• Selenium

• Germanium
