To enhance sleep quality, various supplements have been researched and shown to have potential benefits. Here are the key supplements and their effects:

1. Melatonin: Melatonin is a hormone that regulates the sleep-wake cycle. Supplements can help reduce the time it takes to fall asleep, increase total sleep time, and improve sleep quality¹. Common side effects include headache, dizziness, nausea, and daytime drowsiness².

2. L-Theanine: This amino acid, commonly found in tea leaves, promotes relaxation and can improve sleep quality through its anxiolytic effects without causing daytime drowsiness³.

3. Magnesium: Magnesium plays a role in regulating sleep. Studies have shown magnesium supplementation can improve insomnia, particularly in the elderly, by increasing sleep duration and reducing wakefulness⁴.

4. Vitamin D: Vitamin D deficiency is associated with sleep disorders. Supplementation with vitamin D has been shown to improve sleep quality, although results on sleep quantity and disorders are mixed⁵.

5. Valerian Root: Extracts of valerian root are used to improve sleep quality. Studies have shown that valerian can be effective without producing significant side effects⁶.

6. Magnesium, Melatonin, and Vitamin B Complex: A combination of these supplements has demonstrated significant improvements in insomnia symptoms over a three-month period⁷.

For anyone considering supplements to improve sleep, it is crucial to consult a healthcare professional, as individual needs and potential interactions with other medications can vary.
