Nature Made Magnesium Glycinate 200mg
Multiple Amazon reviewers report needing to take 2-3 capsules to reach a meaningful dose (400-600mg elemental magnesium), which Nature Made's label doesn't clearly communicate. The 200mg per-capsule dose is lower than many competitors, inflating the real cost per effective serving.
Natrol Melatonin 5mg Time Release
Natrol's 5mg dose is flagged by sleep researchers and Reddit users as significantly higher than the 0.5-1mg doses shown effective in studies. Users frequently report grogginess, vivid dreams, and next-day fatigue. Multiple threads on r/sleep recommend cutting the tablet in half or switching to a lower dose.

The Verdict
Magnesium glycinate scores higher for daily sleep support due to no dependency risk, USP-verified quality, and the flexibility to adjust dosing easily. Melatonin is effective for jet lag and short-term sleep onset issues, but Natrol's 5mg dose is 5-10x higher than what most studies use, and tolerance buildup is a common complaint. For nightly use, magnesium glycinate is the more sustainable choice. For occasional use resetting your sleep schedule, melatonin has the faster onset.
