Everybody talk about antioxidants in daily life frequently. Antioxidants are very important for our body. You can find them in any store easily. Their health benefits are beloved by both media and marketers.

But, only a few peoples are there who have complete knowledge about them. Here, we have explained everything related to them such as how antioxidants work, Best Antioxidants Supplement, Highest Antioxidant Foods in The World and many more.

Do You Know What Antioxidants Are And How They Work?

To understand in brief, we have to go through the molecular theory. So, let us start!!!

We all know that all matter in the universe is made of atoms. Atoms are composed of a core with protons and neutrons, and a bunch of electrons that revolve around the core. Go through the image below to understand proper.

What is Antioxidants

The blue balls appearing in the above-given image are electrons that carry negative charge whereas red balls known as protons present at core carry a positive charge. Molecules are a combination of two or more atoms linked together.

The human body is made up of substances like proteins, fats and DNA, which are basically just large molecules with dozens, hundreds or thousands of atoms joined together. Look at the below-given image of the fatty acid molecule where each ball represents an atom.


With the help of chemical reactions, humans and other organisms maintain their structure and function. The sustain life which is required for chemical reaction collectively is known as metabolism.

In the process of chemical reaction, bigger molecules break down into smaller molecules and these smaller molecules make bigger molecules. In order for a molecule to be stable, it must contain the right amount of electrons. If the molecule loses an electron when it isn’t supposed to, it can turn into a free radical.

Free radicals are unstable, electrically charged molecules in the cells that can react with other molecules (like DNA) and damage them. They can even form chain reactions, where the molecules they damage also turn into free radicals. This is where antioxidants come in… If a molecule loses an electron and turns into a free radical, the antioxidant molecule steps in and “gives” the free radical an electron, effectively neutralizing it.

This is how it happens:


This is the process of the mechanism behind antioxidants. They donate electrons to free radicals, which neutralizes them and prevents them from causing harm.

Antioxidants and Free Radicals Are Both Important:

Free radicals are continuously being formed during metabolism. If there will be no antioxidants then our body will destroy very quickly. So, don’t forget that free radicals also serve important functions that are vital for our survival.

We can take an example to understand it, the immune cells of the body use free radicals to kill bacteria that try to infect us or harmful for our body. During oxidative stress, important molecules in the body can become severely damaged… sometimes even leading to cell death.

Several stress factors and lifestyle habits are known to promote the excessive free radical formation and oxidative stress:

  • Air pollution
  • Cigarette smoke
  • Alcohol intake
  • Toxins
  • High blood sugar levels
  • Consuming large amounts of polyunsaturated fatty acids
  • Radiation, including excessive sunbathing
  • Infections by bacteria, fungi or viruses
  • Excessive intake of iron, magnesium, copper, or zinc
  • Too little oxygen in the body
  • Too much oxygen in the body
  • Intense and prolonged exercise, which causes tissue damage
  • Excessive intakes of antioxidants, such as vitamins C and E
  • Antioxidant deficiency

Antioxidants Are Essential for Life and Are Found in All Sorts of Foods:

Antioxidants are vital for the survival of all living things. Even, the human body is able to generate its own antioxidants such as cellular antioxidant glutathione. Infact, plants and animals, and all other forms of life have their own defenses against free radicals and the oxidative damage caused by them. Hence, antioxidants are found in all pretty plants and foods and animal origin.

Here, we are representing some important dietary antioxidants:

Vitamin C: It is a vital dietary nutrient and one of the most important water-soluble antioxidant.

Flavonoids: A large group of antioxidants found in plant foods. These foods have many beneficial health effects.

Many substances that happen to be antioxidants can also have other important functions.
