Life Extension Says Study Finds Brain Benefits for Cognitex Supplement

May 11, 2012

Preliminary results showed a statistically significant improvement in “working memory-n-back,” which allows individuals to hold information in the mind for brief periods of time.

The Life Extension supplements brand says a study performed by the brand on its Cognitex dietary supplement has revealed preliminary results showing benefit for memory and cognitive support.

Cognitex contains many cognitive supporting ingredients, including alpha-glyceryl phosphoryl choline (A-GPC), Sharp-PS Gold phosphatidlyserine, vinpocetine, Leucoselect grape seed extract, BlueActiv blueberry extract, Sensoril ashwagandha, and uridine-5'-monophosphate (disodium). It also contains what the company calls its proprietary NeuroProtection Complex Blend, which includes Perluxan Hops, ginger, and rosemary.

The study on Cognitex was performed by the Life Extension Foundation. It focused on improving cognitive performance in middle-aged to elderly subjects with “subjective memory complaints.” Subjects comprised 40 middle-aged to elderly subjects (29 of whom completed the study), who were given three supplement capsules daily. Changes in cognitive performance were assessed from baseline to day 30 and day 60.

Researchers say that preliminary results showed a statistically significant improvement in “working memory-n-back,” which they describe as a cognitive function that allows individuals to hold information in the mind for brief periods of time, typically only a few seconds (such as when individuals need to remember a phone number when dialing a phone). Improvements were also seen in inspection time (the speed of information intake) and executive function (for planning and problem solving).

The results were presented at the recent Experimental Biology conference in San Diego, CA.
