Antioxidants can be classified in several ways [17, 18].

Antioxidants

Antioxidants are introduced to improve the shelf life of pharmaceuticals. Currently, antioxidants act as efficient excipients that delay or inhibit the oxidation of organic and inor- ganic molecules, preventing the onset and propagation of these reactions.

• Based on their activity, they can be classified as enzymatic and nonenzymatic antioxidants.
• Vitamin C, vitamin E, plant polyphenol, carotenoids, and glutathione are nonenzymatic antioxidants, which act by interrupting free radicals chain reactions.

Your body has its own antioxidant defenses to keep free radicals in check. However, antioxidants are also found in food, especially in fruits, vegetables, and other plant-based, whole foods. Several vitamins, such as vitamins E and C, are effective antioxidants.

CoQ10 has been the focus of scientific study for years and has become one of the most popular dietary supplements. It plays a crucial role in producing energy in cells. It acts as a powerful antioxidant, meaning that it helps neutralize cell-damaging molecules or free radicals.

These natural antioxidants from plant materials are mainly polyphenols (phenolic acids, flavonoids, anthocyanins, lignans and stilbenes), carotenoids (xanthophylls and carotenes) and vitamins (vitamin E and C) [6,20].

Good sources of specific antioxidants include:

• allium sulphur compounds – leeks, onions and garlic.
• anthocyanins – eggplant, grapes and berries.
• beta-carotene – pumpkin, mangoes, apricots, carrots, spinach and parsley.
• catechins – red wine and tea.
• copper – seafood, lean meat, milk and nuts.
