Clinical verdict
Mg malate: good absorption + malic acid (Krebs cycle). Often recommended for fibromyalgia/fatigue but evidence is ONE small pilot study. For sleep: glycinate. For brain: threonate. For constipation: citrate. For energy/fibromyalgia: malate (theoretical basis, weak clinical data) [1] [2].

3 Common questions
Malate vs glycinate vs citrate? ▼
Malate: good absorption, mild laxative, malic acid energy theory. Glycinate: best-tolerated (least laxative), calming glycine. Citrate: good absorption, moderate laxative. Threonate: brain-specific. Choose based on primary goal [1].
Does malic acid really help energy? ▼
Malic acid IS a Krebs cycle intermediate, but oral supplementation's impact on cellular ATP production is NOT established. The fibromyalgia pilot study was small and not replicated [1] [2].
4 Clinical evidence

Strong

Malic acid is a Krebs cycle intermediate — basic biochemistry [1]. Good Mg absorption [1]. HIGH

Moderate

Fibromyalgia: one small pilot study (n=24) showed reduced pain and tenderness with Mg malate (weak evidence) [2]. MODERATE

Insufficient

Chronic fatigue [1]. Energy enhancement beyond Mg repletion [1]. Direct comparison to other Mg forms for clinical outcomes [1]. LOW
