Magnesium Malate Dosage Chart
Magnesium malate combines magnesium with malic acid, a compound involved in the Krebs cycle (cellular energy production). This form is gentler on the digestive system than citrate, highly bioavailable, and particularly popular for fibromyalgia pain and chronic fatigue syndrome where mitochondrial energy production is implicated.
Magnesium Malate Dosage by Age Group
| Age Group | Age Range | Dose Range | Notes |
|---|---|---|---|
| Adults — daily supplement | 18–64 years | 200–400 mg | Elemental magnesium per day |
| Adults — fibromyalgia / chronic fatigue | 18–64 years | 300–450 mg | 300–450 mg elemental Mg; taken in divided doses |
| Seniors (65+) | 65+ years | 200–350 mg | Start low; assess tolerance |
When and how to take Magnesium Malate
Take magnesium malate in the morning or with meals for energy support. Unlike glycinate, it does not have strong sedative properties, making it better suited for daytime use. Split into two doses for amounts above 300 mg elemental magnesium.
Available Forms
Most convenient form.
Elemental magnesium in malate is ~8–15% of the total salt weight
Allows flexible dosing. Dissolves easily in water.
Pleasant slightly tart taste from malic acid
Safety Cautions
- Upper tolerable intake level for supplemental magnesium: 350 mg elemental magnesium/day.
- Very high doses (above 400 mg elemental Mg) may cause loose stools.
- Kidney disease: avoid without physician supervision.
- Malic acid is generally well-tolerated but may cause GI discomfort in sensitive individuals at high doses.
Frequently Asked Questions
How much magnesium malate per day?
For general supplementation, 200–400 mg of elemental magnesium per day is the target. Note that magnesium malate products vary — check the elemental magnesium content on the label, not the total magnesium malate weight. A typical product might list '1,000 mg magnesium malate' providing ~150 mg elemental magnesium.
Is magnesium malate good for fibromyalgia?
Several small studies have used magnesium malate (often combined with malic acid) for fibromyalgia pain with positive results. A 2013 randomized trial found 300 mg elemental magnesium from malate significantly reduced fibromyalgia pain scores at 8 weeks. It is not a cure but may offer adjunct relief.
