Verdict
Magnesium Glycinate wins on 3 of the measurable metrics.
It scores 90/100 against 40/100 on absorption, which is what decides how much of the dose actually reaches you.
What actually differs
Magnesium Glycinate
Highly bioavailable chelated form of magnesium bound to glycine amino acids for superior absorption
- Superior absorption
- Gentle on stomach
- Calming effects
- High quality
- More expensive
- May cause drowsiness
- Lower elemental magnesium %
- Potential hypotension
Magnesium Malate
Highly bioavailable magnesium bound to malic acid, specifically beneficial for energy production and fibromyalgia support
- Energy support
- Fibromyalgia research
- Good absorption
- Gentle on stomach
- Higher cost
- Limited research
- Lower elemental Mg%
- Specialized benefits
What each form is for
Same compound, but the dose, the ceiling and the record differMagnesium Glycinate — superior absorption sleep & muscle support.
Usual daily dose 200-600 mg, taken evening with or without food. The ceiling is 350 mg from supplements a day (NIH ODS). It is named as the suspect product in 379 FDA reports. Evidence grade A.
Magnesium Malate — energy production & fibromyalgia support.
Usual daily dose 600-1200 mg, taken morning and afternoon. The ceiling is 350 mg from supplements a day (NIH ODS). It is named as the suspect product in 379 FDA reports. Evidence grade B.
How these numbers are read
- The absorption score ranks forms of the same compound against each other. It is not a measured share of the dose — see how we derive it.
- Safety rating reflects tolerance at normal doses, not toxicity risk.
- Cost is per month at the typical daily dose, so a cheaper form taken at double the dose is not cheaper.
- Evidence level A means the form itself was studied, not just the parent compound.
Where to buy

Common questions
Which is better, Magnesium Glycinate or Magnesium Malate?
Magnesium Glycinate absorbs better — 90% against 40%. Absorption decides how much of the dose actually reaches you, so it usually matters more than the milligrams printed on the label.
What is the difference between Magnesium Glycinate and Magnesium Malate?
Both deliver the same active compound. They differ in how well the body takes them up, how they are tolerated and what a month costs: $25 against $35.
Can you take Magnesium Glycinate and Magnesium Malate together?
You can, but there is rarely a reason to. Two forms of the same compound stack the same active dose, so the usual approach is to pick the better absorbed one and dose it properly.
