TIENS Grape Extract contains antioxidants, which neutralize free radicals in our organism. Research has shown, that resveratrol, naturally occurring in grapes, supports the circulatory system. Free radicals are molecules, most often of oxygen, which have one or more unpaired electrons. Acting to pair or lose the unpaired electrons, they become highly chemically reactive. They oxidise any compound with which they come in contact. This way they can damage cellular structures, for example membranes, enzymes, nucleic acids or structural proteins. This leads to premature ageing of the body and low immunity. The balance between free radicals and antioxidants in the body is crucial for our health. Often however, we voluntarily destroy this balance by smoking, too much sunbathing, leading a stressful life or through bad eating habits. Antioxidants can help in the battle against free radicals. TIENS Grape Extract is a rich source of many such substances
