Organic magnesium salt paired with glycine; marketed heavily for relaxation and sleep despite magnesium-level evidence limits.
Full verdict →At a glance
Citrate often pulls water into the bowel at higher doses - useful for occasional constipation, tricky if you need tight stool control. Glycinate is marketed for relaxation but the evidence advantage over other tolerated salts is rarely decisive in trials. For both, elemental magnesium content beats storefront adjectives.
Overview
Magnesium citrate: Citrate is not automatically the right choice for every magnesium goal - GI mobility is a feature and a bug.…
Magnesium glycinate: Glycinate is not a sedative on its own - expectations should track magnesium repletion and tolerability.…
Composite scores are tight (74 vs 73 overall). The breakdown below matters more than a single headline number.
Key differences
Derived from score gaps and verdict bands - not brand marketing.
- Evidence scores are within 6 points (70 vs 68) - neither ingredient clearly dominates trial breadth in our rubric.
- Safety headroom looks comparable (78 vs 82) at typical contexts - personal interactions and conditions still dominate.
- Hype gap is similar (40 vs 46); treat aggressive marketing skeptically for both.
- Both map to the same verdict band (“Promising”), so the comparison is mostly about axis-level trade-offs, not label drama.
Comparison table
Higher is better for overall, evidence, and safety. For hype gap, lower is better (less marketing ahead of trials).

Evidence comparison
Human trial breadth and quality for the outcomes people actually shop for - compressed from each hub.
Magnesium citrate
Human repletion trials exist; migraine and constipation contexts have more signal than generic calm claims.
Magnesium glycinate
Often easier on the gut than oxide for equivalent elemental targets in practice reports.
Safety comparison
Tolerability, vulnerable groups, and interaction signals we flag at typical contexts of use.
Magnesium citrate
Bloating and loose stools scale with dose; electrolyte shifts if overused.
Magnesium glycinate
Generally well tolerated; still possible diarrhea if total magnesium is high.
Hype comparison
Where storefront and social claims outrun what trials support - higher hype gap means more disconnect.
Magnesium citrate
Moderate hype relative to oxide; still oversold as a universal best form.
Magnesium glycinate
High lifestyle-brand hype for sleep stacks.
Who each is better for
Heuristic fit from our rubric - not personalized medical advice. Check each hub for avoid lists and interactions.
- Occasional constipation-predominant users discussing osmotic options with clinicians
- People prioritizing GI tolerance while raising magnesium intake
Bottom line
Call it a split decision on the composite: Magnesium citrate and Magnesium glycinate land too close to crown one ingredient outright. Per-axis scores cluster - mechanism fit, tolerance, and clinician context should drive the choice. Read both full verdict pages before changing doses or stacking; our scores compress complexity and are not medical advice.
