Colorful mixture of Antioxidants

Before going into further detail, I would like to discuss about antioxidants and free radicals.

Reaction of oxygen with certain molecules in our body can give rise to free radicals. This process is known as Oxidation. Free radicals are the atoms with an odd number of electrons and highly reactive in nature which can start chain reaction. Because of their unpaired electrons, they are always looking for molecules to react. They can be highly dangerous especially when they react with important cellular components and kill them.

Antioxidants in our body can help to prevent the damage caused by free radicals. Antioxidants react with these free radicals and stop the chain reaction. We need to maintain a balance between antioxidants and free radicals to fight with all kind of diseases.

Vitamin C rich products

Vitamin C or ascorbic acid is the most common antioxidants. Our body can’t store this Vitamin as it’s a water soluble vitamin. That’s why we need to have a continuous supply of Vitamin C as any excess amount will pass through urine.

Vitamin C is found in abundance in citrus fruits like kiwifruit, acerola, camu camu and Indian gooseberry(Amla).

Bell peppers, parsley, broccoli, brussels sprouts, Lychee, strawberries, papaya, Oranges, lime and Cantaloupe are all rich source of Vitamin C.

Apart from that Vitamin C is also found in green leafy vegetables like Kale, Spinach and Cabbage in substantial amount.

Vitamin E

Vitamin E is the fat soluble vitamin. Vitamin E is an antioxidant and can ties up free radicals, which results from oxidation and prevents cell damage. This vitamin may also help in protection against heart disease and cancer.

Vitamin E is found in many nuts and seeds like Sunflower seeds, Almonds, Peanuts, hazelnuts and vegetable oils like olive, corn, safflower, soybean cottonseed or canola oil.

Other sources include eggs and many greens such as Spinach, Avocado, Asparagus, mustard and turnip greens. Vitamin E is also found in abundance in wheat germ.


Beta-carotenes are precursor of Vitamin A. Beta-carotenes are provided byBest Vitamins for Immune System many bright colored vegetables and is converted to Vitamin A by our body as needed.
