Abstract: A method of producing calcium pyruvates is described, in which calcium salts of organic acids or acidic organic keto or hydroxy compounds are reacted with pyruvic acid at a temperature in the range from -20 to +120.degree. C., if necessary in the presence of a solvent or diluent. In this way, high-purity calcium pyruvates are obtained which can be largely free of water and have a very long shelf life.

Abstract: Creatine ascorbates are described which have the general formula (I)(creatine).sub.z (ascorbate).sub.y (H.sub.2 O).sub.n (I)wherez=1 to 100y=1 to 100 andn=0 to 20.These creatine ascorbates, which can be produced by way of the relatively simple reaction of creatine with ascorbic acid, can be used for enhancing muscular development and strength in the field of sport, as prophylactics against and for the treatment of conditions of oxygen deficit (ischemia) and as immune system stimulants in the field of health, for the treatment of muscular atrophy and as food supplements.
