Abstract

The application relates to a method for producing calcium pyruvates, where calcium salts of organic acids or acid organic keto or hydroxy compounds are reacted with pyruvic acid at a temperature ranging from -20 to +120oC, optionally in the presence of a diluent or a solvent. This enables the production of highly pure calcium pyruvates which can be substantially water-free and exhibit very good storage stability. The calcium pyruvates are used to increase stamina and vigour in the field of sports, to reduce weight and fat, and as protective substance for body cells and tissues and as substance for inhibiting the formation of free radicals, as well as free radical scavenger in body cells and tissues in health care and as food additive.
