try with synthetic ones like BHT , BHA and then go for natural ones tocopherol, ascorbic acid and falvonoids

Another option is Trolox (6-hydroxy-2 ,5,7,8-tetramethylchroman-2-carboxylic acid). It is a water-soluble analog of vitamin.

It is widely used as a standard antioxidant compound in several methods available in the literature (DPPH, ABTS, FRAP).

All anti-oxidants available can be used because all have importance in reducing free radicals but most imp are

There are many substances in the body which act as antioxidants, but the three most important frontline antioxidants are

Co-enzyme Q10. This is the most important antioxidant inside mitochondria and also a vital molecule in oxidative phosphorylation. Co-Q10 deficiency may also cause oxidative phosphorylation to go slow because it is the most important receiver and donor of electrons in oxidative phosphorylation. People with low levels of Co Q 10 have low levels of energy.

superoxide dismutase (SODase) is the most important super oxide scavenger in muscles (zinc and copper SODase inside cells, manganese SODase inside mitochondria and zinc and copper extracellular SODase outside cells) , and

glutathione peroxidase. This enzyme is dependent on selenium and glutathione, a 3 amino acid polypeptide, and a vital free radical scavenger in the blood stream.

These molecules are present in parts of a million and are in the frontline process of absorbing free radicals. When they absorb an electron from a free radical both the free radical and the antioxidant are effectively neutralised, but the anti-oxidants re-activate themselves by passing that electron back to second line antioxidants such as vitamins A and beta carotene, some of the B vitamins, vitamin D, vitamin E, vitamin K and probably many others. These are present in parts per thousand. Again, these are neutralised by accepting an electron, but that is then passed back to the ultimate repository of electrons, namely vitamin C, which is present in higher concentrations.
