The Deep Sleep Stack brings together melatonin, magnesium glycinate, and ashwagandha, three ingredients that have been studied extensively for their effects on sleep quality, stress reduction, and nervous system support. 

Research shows that melatonin supplementation can help regulate the body’s natural sleep–wake cycle by decreasing the time it takes to fall asleep, increasing total sleep time, and improving overall sleep quality compared to a placebo. Clinical trials also suggest that melatonin may reduce the number of nocturnal awakenings and support more continuous, restorative rest.

Magnesium has been investigated for its role in relaxation and insomnia management. Studies in older adults have shown that supplementation can lengthen sleep duration, decrease nighttime wakefulness, and improve overall sleep scores. Large cohort studies confirm that higher magnesium intake is associated with better sleep duration and quality, highlighting its importance for nervous system function and relaxation.

Ashwagandha has gained attention as an adaptogen that supports both stress management and sleep. Randomized, double-blind, placebo-controlled trials demonstrate that ashwagandha reduces stress and anxiety, regulates cortisol levels, and improves sleep quality. Meta-analyses further confirm that standardized ashwagandha extracts can improve sleep outcomes, particularly when taken consistently over several weeks. Its calming effects on both the mind and body make it an ideal complement to melatonin and magnesium in a holistic sleep-supporting formula.

Together, these three ingredients target different aspects of the sleep process. Melatonin regulates circadian rhythm, magnesium relaxes muscles and supports the nervous system, and ashwagandha eases mental stress that can interfere with rest. By addressing these pathways simultaneously, the Deep Sleep Stack provides a comprehensive approach to deeper, more restorative sleep.
