Quick Answer
The best magnesium supplement in 2026 is Thorne Magnesium Bisglycinate because it uses the form most people actually want—glycinate—without padding the formula with cheaper oxide. If your goal is sleep support and calm, start there; if your goal is bowel regularity, NOW Foods Magnesium Citrate Softgels makes more sense.

Thorne Magnesium Bisglycinate Is the One Most People Should Buy
Most people shopping for magnesium want the form that is easiest to tolerate and most likely to become part of a nightly routine. Thorne is giving you bisglycinate, not pretending oxide is the same thing. This is the magnesium for sleep support, stress management, and people who tend to get stomach issues from harsher forms.
Pure Encapsulations Magnesium Glycinate Is the Cleaner-Label Runner-Up
Very close to Thorne. For very supplement-literate buyers who care about stripped-down formulas, Pure Encapsulations is arguably just as compelling.
NOW Foods Magnesium Citrate Softgels Are Better If You Want a GI Effect
If your real goal is bowel regularity, citrate makes more sense than glycinate. “Best magnesium” is always incomplete unless you name the form.
Life Extension Neuro-Mag Magnesium L-Threonate Is the Brain-Optimization Option
For people who want magnesium through a cognitive-performance lens. It is also the form most likely to be overpriced relative to elemental magnesium value.
Natural Vitality Calm Magnesium Citrate Powder Is the Ritual Magnesium
Wins on user experience, not purity. If you want a warm evening drink and a supplement that feels like a calming ritual rather than another capsule.
Nature Made Magnesium Oxide 250mg Is the Cheap One, Not the Smart One
Oxide is not the form I would recommend unless your entire brief is “I want the cheapest possible bottle.”
