この研究の注釈：
Oral ingestion of 2.1g D-serine in otherwise healthy adult subjects two hours prior to cognitive testing (CPT-IP for sustained attention, BVRT, and RAVLT) in a double-blind crossover study found that supplementation reduced testing anxiety and sadness (no influence on reaction time) alongside the main parameter of increased working memory (word retention and immediate recall).

Other tests involved backwards recall (not superior to placebo) and forward (benefits of D-serine over placebo) with an improvement in the Category Fluency test. On the BVRT, D-serine was significantly better than baseline values but due to a nonsignificant increase in placebo there was no difference between groups.
