In a randomized, double-blind, placebo-controlled trial of 73 healthy middle-aged adults, Dr. Talitha Best and colleagues from the University of South Australia and Swinburne University of Technology showed that, shortly after taking a single 4-gram serving of classic Ambrotose® complex powder, subjects experienced significantly improved memory and performed significantly better on demanding cognitive tasks. The product had no effect on blood glucose levels.* Study was at least partially funded by Mannatech.
