Drs. Atiya N. Stancil and Leslie H. Hicks, both of Howard University in Washington, D.C., published this randomized, double-blind, placebo-controlled study investigating the impact of Ambrotose® complex on the brain function of 62 healthy young adults. The study showed that a single, one-tablespoon serving of Ambrotose complex significantly improved visual discrimination and working memory. Study was at least partially funded by Mannatech.
