Antioxidants are a group of biochemical substances that purify the body. Their main property is the removal of free radicals - heavy metals and toxins , releasing poisonous oxides. Antioxidants also protect the body from viruses and bacteria and strengthen the immune system . We get antioxidants through the foods we eat, but often they are not enough for the body's needs. That is why extracts are extracted from the richest plants in antioxidants , which supplement the antioxidant intake. The most famous natural sources of antioxidants are acai berry , macchi berry , raspberry ketones , artichoke , milk thistle, spirulina and others. We advise you to always buy antioxidants from proven manufacturers such as Biovea , BiomedX , Now Foods , Sanct Bernhard and 21th Century Healthcare .
