Supplement
Malic Acid
SaveAn organic acid found in apples and involved in the Krebs cycle of cellular energy production. Often combined with magnesium (as magnesium malate) for fibromyalgia and energy support.
Quick verdict
Limited evidence as a standalone supplement. Most commonly studied in combination with magnesium for fibromyalgia, with mixed results.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Malic acid is a Krebs cycle intermediate that supports ATP production. Magnesium malate has been studied for fibromyalgia pain with some positive results, but trial quality is generally low. Standalone malic acid supplementation data is very limited.
Benefits
- Krebs cycle intermediate supporting cellular energy production
- May reduce muscle pain and fatigue in combination with magnesium
- Natural chelating agent for mineral absorption
Dosage notes
Typical doses: 1200-2400 mg daily, often as magnesium malate providing both magnesium and malic acid. Usually split into two or three doses.
Side effects
- GI discomfort
- Diarrhea at high doses
- Dental erosion with chronic acidic exposure
Who should be cautious
Acidic; may cause GI irritation. Dental erosion risk with frequent oral exposure to acidic solutions.
What this page cannot tell you
Most interest is in the magnesium malate combination rather than standalone malic acid. Fibromyalgia evidence is preliminary and inconsistent.
