Abstract: The use of guanidinoacetic acid and/or salts thereof in combination with choline and/or betaine to produce an agent for improving brain function, bone growth and the mineralization of bones, for improving cartilage growth, for alleviating aging processes, for strengthening the immune system, as an antioxidative and neuroprotective agent, for lowering the cholesterol and triglyceride value, for preventing inflammatory processes and for lowering the blood sugar level in humans and vertebrates is described. In this connection it has surprisingly turned out that the new agents have a considerably higher bioavailability and are thus better taken up into the cells than was previously known when using creatine.

Abstract: The invention relates to the use of aqueous guanidinium formiate solutions, optionally combined with urea and/or ammonia and/or ammonium salts, for the selective catalytic reduction of nitrogen oxides using ammonia in exhaust gases of vehicles. The inventive guanidinium formiate solutions enable a reduction of the nitrogen oxides by approximately 90%. Furthermore, said guanidinium formiate solutions can enable an increase in the ammonia forming potential from 0.2 kg, corresponding to prior art, up to 0.4 kg ammonia per liter of guanidinium formiate, along with freezing resistance (freezing point below ?25° C.). The risk of corrosion of the inventive guanidinium formiate solutions is also significantly reduced compared to that of solutions containing ammonium formiate.

Abstract: The present invention relates to the use of guanidinoacetic acid and/or salts thereof as feed additive, in predominantly vegetarian diets, in particular use being made of salts with hydrochloric acid, hydrobromic acid and phosphoric acid. The use proceeds especially in individual doses from 0.01 to 100 g/kg of feed in the form of powders, granules, pastilles or capsules, the feed additive also being able to be used in combination with other physiologically active materials of value. The claimed use which is suitable especially for breeding and growing livestock, has recourse to a compound which is in particular stable in aqueous solution, can be converted to creatine under physiological conditions, and, in contrast to other guanidine derivatives, is completely available to physiological sectors of use.
