Context
L-tryptophan (Trp) has been documented to aid sleep, but a systematic compilation of its effect on sleep quality is still limited. Objective We assessed the effect of Trp supplementation on sleep quality via meta-analysis and meta-regression. The effects of daily Trp dose ( Data sources A database search was done in PubMed, Medline (Ovid), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Cochrane and a total of 18 articles were collected. Data extraction Extracted data from 4 articles were also analyzed using random-effect meta-analysis and meta-regression. Standardized mean difference (SMD) was used in meta-analysis. Data analysis Results from the study suggested that Trp supplementation can shorten wake after sleep onset (−81.03 min/g, P = 0.017; SMD, −1.08 min [95%CI, −1.89 to −0.28]). In addition, the group receiving ≥1 g Trp supplementation had a shorter wake after sleep onset than the group with Trp Conclusion Trp supplementation, especially at ≥1 g can help improve sleep quality. |
