Nature Made Magnesium Glycinate 200mg

Walmart and Amazon reviewers consistently flag Nature Made's capsules as large enough to catch in the throat, requiring multiple glasses of water to swallow — a dealbreaker for users who already struggle with pills. A 2024–2025 wave of Walmart reviews mentions a formulation change ('new bottle looked different, strange taste'), and label-reading reviewers note magnesium stearate as a filler. The 200mg-per-capsule dose is also at the low end: users targeting a therapeutic 400mg need two capsules, cutting the 60-count bottle to a 30-day supply.

Natrol Melatonin 5mg Time Release

Each Natrol tablet contains 10mg of vitamin B6 — 588% of the daily value — and one Amazon reviewer reported facial tingling and altered foot sensation after 5 months of nightly use, consistent with the chronic-dose neuropathy risk documented in published B6 literature. The 5mg melatonin dose is also 10–25× the 0.2–0.5mg range that sleep research identifies as physiologically effective, and next-day grogginess is a recurring theme in Walmart and iHerb reviews. Several reviewers also question the 'time release' claim: tablets reportedly look identical to regular melatonin with no visible layers.

The Verdict

Choose Nature Made Magnesium Glycinate for nightly long-term sleep support — the USP Verified certification, chronic-use safety profile, and dose sitting within sleep-research range make it a defensible daily habit. Choose Natrol Melatonin only for situational jet-lag or shift-work dosing over days, not months; the 5mg melatonin dose is 10× physiological and the 588% DV B6 payload is not something to accumulate nightly for years.
