# GlyNAC improves multiple defects in aging to boost strength and cognition in older humans
A pilot human clinical trial conducted by researchers at Baylor College of Medicine reveals that supplementation with GlyNAC—a combination of glycine and N-acetylcysteine as precursors of the natural antioxidant glutathione—could improve many age-associated defects in older humans to improve muscle strength and cognition, and promote healthy aging.
I’m posting this here because I recall that both glycine and N-acetylcysteine have been trialed in schizophrenia. Would be great if this small pilot study is later replicated in a larger study.
I would like to caution readers, because too often pilot studies were later refuted by larger studies. But it’s good that at least there’s some active reasearch.
