Based on meta-analysis of 437 participants showing improvements in attention, processing speed, and working memory. However, one large RCT (n=101) found no significant between-group differences. Effects may take 8-12 weeks to manifest. Standardized extracts (Bacognize, Synapsa) may have better bioavailability than generic forms.
Based on single RCT (n=160) showing sleep improvement with various supplements including L-serine. Conservative estimates given limited direct evidence and lack of dose-specific data for L-serine alone. Effect likely mediated through conversion to glycine.
