L-citrulline-alpha-ketoglutaric acid (synonym: alpha-ketoglutarate citrulline), the combination of L-citrulline with alpha-ketoglutarate. L-citrulline mediates the metabolic cycle urea synthesis from ammonia and nitrogen excretion. It is an intermediate compound in a metabolic cycle of urea synthesis from ammonia and glutamic acid. Synthesizes polyamines, regenerating liver. It improves the exercise capacity, maintains acid-base balance, reduces the feeling of fatigue. Alpha-ketoglutarate participates in the metabolism of amino acids, oxidation process , and during transport of the nitrogen in the body. It accelerates the synthesis of food components (anti-catabolism). Formulations containing L-Citruline-alpha-ketoglutaric are widely applied in the disciplines of strength, endurance-strength and endurance at every level of training, pre-, during, and post-workout.
