Supplements for Sleep Quality

What the Research Shows

Several supplements have been studied for their potential to improve sleep quality, with moderate evidence supporting the use of 5-HTP, L-Theanine, Lavender, and Tryptophan. Specifically, L-Theanine and Tryptophan have been highlighted in systematic reviews and meta-analyses for their positive effects on overall sleep quality and the ability to fall asleep more easily. Similarly, 5-HTP has shown promise in improving both mood and sleep quality, particularly among older adults. Lavender has also demonstrated moderate evidence for improving sleep across diverse groups, including postmenopausal women with insomnia, chemotherapy patients, and individuals without diagnosed sleep disorders. While these findings are encouraging, it is important to consult with a healthcare provider before starting any new supplement to ensure there are no adverse interactions with existing medications or underlying health conditions.
