American Ginseng Extract
Also known as: Panax quinquefolius, Cereboost, Wisconsin ginseng, American ginseng root
The root of a ginseng species native to North America, used in focus and calm-energy formulas. Its ginsenoside profile differs from Asian ginseng and it is generally considered less stimulating. An acute crossover trial of the Cereboost extract at 100 to 400 mg found improvements in working memory and reaction-time accuracy in healthy adults. It is a natural fit for nootropic blends that need a non-caffeine cognitive component.
Research summary
Ginsenosides, particularly Rb1, may support cholinergic activity and glucose handling in the brain, contributing to short-term cognitive effects.
