Spirit Sciences RU-21 is one of the world's most trusted brands used by millions of people on all five con-tinents. Consumer satisfaction and word of mouth have been the driving forces behind RU-21's success. From Los Angeles to London, from Seoul to Melbourne, from Moscow to Solomon Islands, from Kenya to Beijing, RU-21 makes the world a better, hangover-free, place for partygoers! To assist the body in processing alcohol, ingredients in RU-21 enable certain biochemical reactions that enhance enzyme functions of the body, while oxygenating the cells, keeping the energy levels up and metabolic pathways running properly. RU-21 is a dietary supplement. All ingredients are considered GRAS (Generally Regarded As Safe) by the USFDA.

Vitamin C Vitamin C activates anti-oxidant systems of the central nervous system, liver and hormone-active tissues and supports the adrenal gland cortex, which produces anti-stress hormones.

Succinic and Fumaric Acids Succinic and Fumaric acids are substrates which are crucial to alcohol metabolism, and important in the Krebs cycle. Succinic and Fumaric acids boost the aerobic oxidation process in mitochondria by activating the second half-cycle of tricarboxylic acids. Succinic substrate, which is independent of NADH-dehydrogenase, prevents the toxic byproducts of ethanol metabolism from causing hypoxia, which often results from the accumulation of suboxidized metabolites, and from impeding NADH oxidation in the respiratory chain of cells.

L-Glutamic Acid HCL L-Glutamic Acid HCL speeds up the mitochondria-cytosolic malate-aspartate shuttle, which plays a key role in the course of toxic byproduct development. It also speeds up the succinate oxidation process (by preventing oxalic and acetic inhibition of succinate dehydrogenase). In addition, it transforms itself into a-ketoglutarate during a rapid oxidation in the Krebs cycle. The proper concentration of L-Glutamic Acid HCL positively influences glutamate and GAMC synapses in the brain, improving coordination and inhibition processes.

Vitamin B2 Vitamin B2 is essential for the metabolism of carbohydrates (to produce energy) and amino acids. It also helps keep mucous membranes (such as those lining the mouth) healthy. Riboflavin is further needed to activate vitamin B6 (pyridoxine), helps to create niacin and assists the adrenal gland.
Vitamin B6 Vitamin B6 is needed for the synthesis of neurotransmitters such as serotonin and dopamine. These neurotransmitters are required for normal nerve cell communication. Vitamin B6 increases oxygenation of tissues by helping the body produce hemoglobin, which is responsible for carrying oxygen to tissues within red blood cells.
