Magtein PS supports cognitive health in aging subjects according to recent study

Published on: 

Subjects taking Magtein PS for 30 days saw significant improvements in cognitive health parameters.

AIDP (City of Industry, CA) has announced the publication of a study1 demonstrating that its Magtein PS ingredient, a magnesium L-threonate (Magtein)- and phosphatidylserine-based formulation additionally containing vitamins C and D, supports cognitive health. In the study 109 healthy Chinese adults between the ages of 18 and 65 were randomly assigned to receive either Magtein PS or placebo capsules at a dose of 2 grams per day. Subjects took “The Clinical Memory Test”, the standard test commonly used in Chinese hospitals and academic institutes for cognitive evaluation, at baseline and after 30 days of supplementation.

Results showed that subjects taking Magtein PS saw significant increases in the average score for directed memory (DM), paired-association learning (PAL), free recall of pictures (FRP), recognition of meaningless figures (RMF), portrait-features memory (PFM) and memory quotient (MQ) compared to the placebo group. Additionally, older subjects saw greater improvements than younger subjects.

“This study is the third human clinical publication in healthy adults and validates, Magtein’s cognitive support for a broad age group as well as an ethic group,” said Jennifer Gu, PhD, vice president of research and development at AIDP, Inc., in a press release. “There is a significant research pipeline for Magtein, and we are pleased with this recent publication.”
