Rapid Mental Energy combines clinically studied extracts, Alpinia galanga (enXtra) and American ginseng (Cereboost), to support alertness and sharpen working memory. In a randomized, double-blind, placebo-controlled crossover study, enXtra significantly increased alertness scores from baseline values at 1 hour, 3 hours and 5 hours after a single 300 mg dose. Alertness scores were significantly greater in the enXtra group compared to placebo (p=0.04) at 3 hours post-dose. While enXtra supports alertness and attention network function (the ability to direct mental resources to a specific task), Cereboost provides fast-acting support for acute visuospatial and verbal short-term (working) memory. in a study of 52 healthy middle-aged adults, Cereboost (200 mg) improved working memory 3 hours after a single dose. In a randomized controlled clinical trial of 61 healthy young adults, daily use of Cereboost (200 mg) improved working memory and attention. In a randomized, double-blind crossover trial of 32 healthy volunteers, a single dose of Cereboost (200 mg) improved working memory (immediate word recall and visuo-spatial information retrieval) at 1 hour post-dose and was sustained over a 6 hour testing period.4 The ginsenosides in Cereboost support cholinergic neurotransmission in the hippocampus and prefrontal cortex, key brain regions involved in learning and memory.
