GLYCINE AND MEMORY
Lawrenceville, NJ (Dr Simone) – The effects of Glycine, an amino acid, on attention and memory was tested on 20 year olds and middle-aged men (mean age 58) using a double-blind, randomized, crossover design. The middle-aged group had poorer verbal memory and sustained attention. Glycine improved retrieval from memory in both groups but it did not affect focused or divided attention. However, glycine aided middle-aged men in the sustained-attention task. Glycine did not seem to have stimulant properties and it primarily improved memory rather than attention.
