The Claim
Some assert that glycine can enhance cognitive abilities, such as memory and concentration, in healthy adults.
Origin
This belief may be rooted in glycine's role as a neurotransmitter and its potential effects observed in neurodegenerative disease research.
What Science Says
Evidence does not strongly support glycine as a cognitive enhancer in healthy adults. While a few studies suggest some benefit in people with cognitive impairments, such as schizophrenia, there is little evidence from RCTs or meta-analyses showing significant cognitive improvements in healthy populations.
Verdict
Mostly False
