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.

NOW Magnesium Glycinate 200mg

NOW's tablet format requires a 3-tablet serving to reach 200mg elemental magnesium, which Amazon reviewers describe as a heavy pill burden compared to single-capsule competitors. The label also reads '1 to 2 times daily,' so users chasing a 400mg therapeutic dose would swallow 4 tablets per day. iHerb and Amazon reviewers note the tablet is harder to swallow than the capsule formats they're used to, and at ~$30 per 240-count bottle the 30–60 day runway is shorter than Nature Made's 60-count at half the price.

The Verdict

Choose Nature Made if you want single-capsule convenience and the lowest cost per milligram — its USP Verified certification plus 1-capsule serving beats NOW on both pill burden and price. Choose NOW only if you specifically prefer the tablet format or want the broader GMP + ISO/IEC third-party testing stack; the 3-tablet serving makes it a poor fit for anyone targeting 400mg+ nightly.
