Supplements studied for improving sleep quality

While melatonin is widely recognized for regulating sleep-wake cycles, several other supplements have been studied for their potential to improve sleep quality. Scientific evidence varies regarding their effectiveness and optimal dosage.

Magnesium is an essential mineral that may aid sleep by regulating circadian rhythms, assisting in muscle relaxation, and contributing to the release of neurotransmitters like GABA and melatonin. Low magnesium levels have been linked to insomnia and poor sleep quality.

Zinc also plays a role in sleep regulation by potentially influencing melatonin production and secretion. Some clinical studies suggest zinc may help improve sleep quality and reduce insomnia severity in certain individuals. Additionally, Vitamin D and various herbal or amino acid compounds are being investigated for their impact on sleep cycles.
