COMPOSITION FOR INCREASING ENERGY IN VIVO

PROBLEM TO BE SOLVED: To orally administer precursors of adenosine triphosphate to increase intracellular ATP concentration or for treatment of reduced energy availability resulting from strenuous physical activity, illness or trauma to mammals.SOLUTION: Pentose sugars are administered individually, mixed into dry food or in solution. The preferred pentose is ribose, singly or combined with creatine, pyruvate, L-carnitine and/or vasodilating agents. Additionally, magnesium, electrolytes, fatty acids and hexose sugars can be used. The compositions and methods are especially beneficial to mammals having reduced energy availability or high energy demand.
