Reports are voluntary and unverified — they record what someone experienced while taking something, not what the compound caused. Counts skew towards products people take a lot of, and a serious outcome is more likely to be reported than a mild one, so these are not rates. How we filter them →

What else affects it
Beyond other supplements
!
Aluminum
Aluminum may interfere with magnesium function
Competitive interference in enzyme systemsHow it works
- Malic acid participates directly in Krebs cycle for ATP production
- Enhanced magnesium absorption due to malic acid chelation
- Supports mitochondrial function and cellular energy metabolism
- May help remove aluminum and other toxic metals
- Improves muscle cell energy availability
- Reduces muscle hyperexcitability and pain sensitivity
Key findings
what the evidence supports- Promising results for fibromyalgia symptom reduction (pilot studies)
- May improve energy levels in chronic fatigue syndrome
- Good bioavailability and tolerance in clinical observations
- Potential for supporting cellular energy production
