Abstract: The invention relates to the brewing and non-alcoholic industry and specifically for production of beer, low-alcohol and alcohol-free drinks The “Antioxilen” additive for beer, alcohol-free drinks contains an organic selenium compound—di-(3,4)-methyldipyrazolylselenide (DMDPS)—and also succinic acid and salts thereof (ammonium succinate or sodium succinate) as an antioxidant. The method of conditioning (enriching) drinks involves increasing biological value, improving quality and contributing antioxidant, antitoxic and hepatoprotective properties to drinks, i.e. protective properties for a human organism by adding the above additive to the finished product (drink). The additive is added in the form of a dry mixture or a solution. The invention allows for improving biological value of the product (drink), taste and useful properties thereof and also extending the “life” thereof.
