Can you take magnesium with levetiracetam?

By George Thomas. Published 11 December 2026, updated 11 December 2026. Label figures and prices checked on the update date.

The short answer

Yes: levetiracetam is absorbed almost completely, is not chelated by minerals, is not metabolised by the liver enzymes that drive most interactions and is cleared by the kidneys, so magnesium glycinate sits beside it freely. Three notes: severe magnesium deficiency lowers the seizure threshold, the neurologist should know every supplement, and no supplement replaces an antiseizure medicine.

  • The interactionnone: not chelated, not liver-metabolised, kidney-cleared
  • The seizure thresholdsevere hypomagnesaemia lowers it: adequacy matters, corrected in hospital when severe
  • The neurologisttells them every supplement; the kidneys clear both, so kidney function matters for both
  • The lineoral magnesium is never a treatment for epilepsy and never adjusts a medicine

Yes, and the pharmacology that makes levetiracetam one of the cleanest medicines to take a supplement beside

Can you take magnesium with levetiracetam: yes, and the reason is the drug's pharmacology, which gives it one of the cleanest interaction profiles in medicine. Levetiracetam is absorbed almost completely from the gut, is not bound to plasma proteins to any degree, is not chelated by minerals in the way the tetracyclines and fluoroquinolones are, is not metabolised by the liver's cytochrome enzymes that drive most drug interactions, and is cleared largely unchanged by the kidneys, so that a magnesium salt in the gut neither binds it nor competes with it, and the two share no metabolic pathway, no absorption route and no documented interaction, the medicines traffic light placing levetiracetam nowhere on the green, amber or red lists and a magnesium glycinate capsule sitting beside it at the same meal or a different one without a spacing rule. The one shared feature is the kidneys, both levetiracetam and surplus magnesium being cleared by them, which is not an interaction but a note: a reader whose kidney function is impaired has their levetiracetam dose adjusted by the neurologist for that reason and takes magnesium only on advice for the same reason, the safety pages' red gate applying to both. The standing rule applies as always, the whole cupboard past a pharmacist once, and the pharmacist will confirm that levetiracetam needs no spacing from any mineral.

Three notes for a reader with epilepsy, the seizure threshold, the neurologist and the line, and the pair filed

Three notes matter more than the interaction for a reader with epilepsy. The seizure threshold: severe hypomagnesaemia lowers it, a clinically low magnesium from alcohol, medicines, gut loss or a diet that ran badly light being a recognised provoking factor for seizures and corrected with intravenous magnesium in hospital when severe, so magnesium adequacy matters for a reader with epilepsy as one of the general conditions of seizure control alongside sleep, alcohol and adherence, and a reader whose diet audit finds intake short has a reason to close the shortfall at a labelled dose, 300mg elemental as bisglycinate, within guidance and on the neurologist's knowledge. The neurologist: every supplement a reader with epilepsy takes is told to the neurologist or epilepsy nurse, magnesium included, both because the team keeps the whole picture and because some supplements, botanicals above all, do interact with antiseizure medicines or affect the threshold, the herbal drawer being where the real epilepsy cautions live and magnesium being the innocent one on the shelf. The line a supplement never crosses: oral magnesium is not a treatment for epilepsy, never replaces levetiracetam or any antiseizure medicine, and never justifies a change of dose, a reader who reads that magnesium calms the nervous system and wonders about reducing their medicine having read a maintenance claim, normal nervous system function in a replete person, and not a treatment, the register holding no seizure, epilepsy or convulsion claim for any supplement and the consequence of a missed or reduced dose being a seizure. The pair filed: magnesium with levetiracetam is fine, with no interaction on a drug built to have few, the kidneys being the one shared note, adequacy mattering for the threshold, the neurologist knowing, and the line never crossed, the worked example being the supplement with no interaction and an honest place beside the medicine, 300mg elemental at 22p, £19.99 for 90 days, taken for its own sentences and mentioned at the next clinic.

The verdict, fine together, with three notes that matter more

Can you take magnesium with levetiracetam: yes, levetiracetam being absorbed almost completely, not chelated by minerals, not metabolised by the liver enzymes that drive most interactions and cleared by the kidneys, so that magnesium glycinate sits beside it freely with no spacing, and with three notes that matter more for a reader with epilepsy, that severe magnesium deficiency lowers the seizure threshold so adequacy matters, that the neurologist should know every supplement taken, and that no supplement ever treats epilepsy or justifies changing an antiseizure medicine. The supplement with an honest place: Futuro Labs Magnesium Glycinate, bisglycinate, 300mg elemental at 80% NRV, £19.99 for 90 days at 22p a day.

What to check on the label

  • Take them together freely: no interaction on a drug built to have few.
  • Note the shared kidneys: impaired function means advice for both.
  • Keep magnesium adequate: severe deficiency lowers the seizure threshold.
  • Tell the neurologist: every supplement, botanicals especially.
  • Never adjust the medicine: a maintenance claim is not a treatment.

Questions people also ask

Does magnesium interact with levetiracetam?

No: levetiracetam is absorbed almost completely, is not chelated by minerals, is not metabolised by the liver enzymes behind most interactions and is cleared by the kidneys, so magnesium glycinate sits beside it at any hour with no spacing rule.

Can low magnesium trigger seizures?

Severe hypomagnesaemia lowers the seizure threshold and is a recognised provoking factor, corrected with intravenous magnesium in hospital when severe, so magnesium adequacy matters for a reader with epilepsy alongside sleep, alcohol and adherence.

Can magnesium replace or reduce my epilepsy medication?

Never: oral magnesium is not a treatment for epilepsy, the register holds no seizure claim for any supplement, and a maintenance claim about normal nervous system function is not a reason to change a dose, the consequence of which can be a seizure.

Should I tell my neurologist I take magnesium?

Yes, as with every supplement: the team keeps the whole picture, botanical supplements can interact with antiseizure medicines or affect the threshold, and magnesium is the innocent one on the shelf they will be glad to know about.

Does kidney function matter for magnesium and levetiracetam?

Yes for both: levetiracetam is dosed by kidney function and surplus magnesium is cleared by it, so a reader with impaired kidneys takes both on the team's advice, an overlap rather than an interaction.

  3. The magnesium and medicines literature: magnesium supplements reduce absorption of tetracycline and quinolone antibiotics, bisphosphonates and levothyroxine when taken together and are spaced from them, while proton-pump inhibitors and some diuretics lower magnesium status, a reason for medical advice in either direction. PubMed record
  4. The hypermagnesaemia literature: the kidneys excrete surplus magnesium, so supplementation is safe for healthy adults within guidance and warrants medical advice in chronic kidney disease, where impaired excretion allows magnesium to accumulate. PubMed record
