Abstract: Dietary supplement formulation which increases lean body mass without concomitant increase of body fat mass, an effect parallel to that seen with usage of synthetic anabolic steroidal compounds but without adverse side-effects. The formulation composition of the invention comprises creatine, taurine, ribonucleic acid, and optimally, a carbohydrate (starch or a simple saccharide)component for enhancing cellular uptake. Other components such as alpha-ketoglutaric acid and salts thereof, and beta-hydroxy-beta-methyl butyric acid and salts thereof can be added for optimal results. The composition may be taken alone or in combination with a nutrient base, which typically includes protein source(s), carbohydrate(s), vitamin(s), and mineral(s) and other amino acids such as L-Glutamine and other natural L-form non-branched chain or branched chain amino acids. Actual studies in weight trained men show statistically significant increases in lean body mass yet with decreases in fat mass within 28 days.

Abstract: A method is disclosed for lowering the concentration of a serum lipid or lipoprotein component in a mammal, including the step of administering to a mammal in need of such treatment a hypolipidemic, therapeutically effective amount of at least one creatine derivative.
