Summary

This study tested whether taking 1,000 mg of glycine daily for six months could improve memory and thinking in older adults. Fifty-nine participants took the supplement, and researchers measured changes in a brain health marker and cognitive test scores. The goal was to see if this safe, affordable supplement could support healthy aging.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Glycine (dietary supplement)
What this could lead to: If it works, this could point toward a simple, safe supplement to help older adults maintain memory and thinking skills.
What could go wrong: This was a small, completed trial with only 59 participants, so results may not apply to everyone. The effects on cognition were measured with a screening test, not a full diagnostic tool.
