What is Magnesium Pidolate?
1Magnesium pidolate is also listed as magnesium 2-pyrrolidone-5-carboxylate and pidolic acid magnesium salt (2:1). PubChem identifies it as a compound containing magnesium and L-pyroglutamic acid components.
Names, aliases and forms
Mechanisms of action
Mechanism and cognitive relevance
3A form-specific review discusses magnesium pidolate in the context of magnesium and headache literature. It does not establish a cognitive mechanism or nootropic benefit for magnesium pidolate.
Potential effects and evidence map
Magnesium pidolate has no established nootropic benefit. A 2024 systematic review found the randomized-trial evidence on magnesium supplements insufficient for cognitive conclusions; it does not establish a cognitive effect for this specific magnesium form.
Evidence is insufficient to draw cognitive conclusions for magnesium supplements and does not establish a focus or attention effect for magnesium pidolate.
Typical dosages and timing
The reviewed evidence does not establish a general dosage for cognitive performance with magnesium pidolate.
Timing & effect horizon
No onset, peak, or duration has been established for a cognitive effect of magnesium pidolate.
Safety, side effects and risk profile
High intakes of magnesium from dietary supplements and medications can cause diarrhea, nausea, and abdominal cramping.
The risk of magnesium toxicity increases when impaired kidney function reduces the ability to remove excess magnesium.
Magnesium can reduce absorption of oral bisphosphonates and form insoluble complexes with tetracycline and quinolone antibiotics.
At high supplemental or medication intakes, NIH ODS lists diarrhea, nausea, and abdominal cramping among magnesium's gastrointestinal effects.
Interactions and cautions
NIH ODS flags timing and absorption interactions between magnesium and oral bisphosphonates, tetracycline antibiotics, and quinolone antibiotics. Ask a clinician or pharmacist about regular medicines.
How it compares
Magnesium pidolate is the magnesium 2-pyrrolidone-5-carboxylate form. Its chemical identity distinguishes it from other magnesium salts, but does not itself establish a nootropic difference.
Practical buying and quality notes
- A Supplement Facts panel declares elemental magnesium, not the weight of the entire magnesium-containing compound. Use the label to understand the amount of magnesium provided per serving.4
FAQ
Is magnesium pidolate a nootropic?
2No established nootropic benefit has been shown for magnesium pidolate. The cited systematic review found the randomized-trial evidence on magnesium supplements insufficient for cognitive conclusions and did not test this form specifically.
