Magnesium comparison
Best Magnesium Supplements Compared (2026): EDE Scored Reviews
Magnesium is the most under-consumed essential mineral in Western diets, with 50+ percent of US adults failing to meet the 400-420 mg RDA. Supplementation supports sleep, muscle recovery, blood pressure regulation, insulin sensitivity, and bone health. Form selection matters more here than for any other mineral: oxide is poorly absorbed and laxative, while glycinate, bisglycinate, malate, and citrate deliver clinical effects.
All 4 products in our catalog use chelated forms (glycinate or bisglycinate). The Editor's Pick balances clinical full dose, NSF Sport availability, and Tier 1 manufacturer reputation.

Frequently asked questions
- What form of magnesium absorbs best?
- Magnesium glycinate and bisglycinate (zinc-glycine chelates) are the gold standard for sleep and general support. Magnesium malate suits muscle recovery. Magnesium L-threonate uniquely crosses the blood-brain barrier for cognitive endpoints. Avoid magnesium oxide; absorption is approximately 4 percent.
- How much magnesium should men 40+ take?
- RDA is 400-420 mg/day for adult men; clinical supplementation typically uses 200-400 mg elemental magnesium daily on top of dietary intake. The Tolerable Upper Limit for supplemental magnesium is 350 mg/day to avoid laxative effects. Stay below this from supplements alone.
- Should I take magnesium for sleep?
- Yes, glycinate or bisglycinate at 200-400 mg taken 30-60 minutes before bed has the strongest evidence for sleep onset and quality, particularly in users with low magnesium status. Effects are gentle (not sedating like melatonin) and accumulate over 1-2 weeks.
- Can I take magnesium with calcium or zinc?
- Separate them by at least 2 hours. High-dose calcium and zinc compete with magnesium for the same intestinal transporters. The simplest split: zinc with breakfast, magnesium before bed.
