Supplements and Seizure Risk: What to Ask First
Supplements and seizure risk are linked for a few ingredients, so ask your doctor or pharmacist before any memory capsule if you have a seizure history or take seizure medicine. Ginkgo and carnitine have seizure cautions, and St. John's wort can weaken some seizure drugs. Keep taking prescribed medicine.

The short answer01
Which supplements affect seizure risk?
Ginkgo, carnitine and St. John's wort all carry a seizure-related caution in the sources we cite.
Memorial Sloan Kettering lists seizures with ginkgo in predisposed patients or those on medicines that lowered the seizure threshold (MSK, Ginkgo). NIH says carnitine at about 3 g a day can cause seizures in people with seizure disorders (NIH ODS, Carnitine). NCCIH says St. John's wort can weaken some seizure drugs (NCCIH, St. John's Wort safety).
Natural does not mean risk free (NCCIH, Using Supplements Wisely). A seizure history is a plain reason to ask first.
Never stop seizure medicine because of a supplement. Check with your doctor or pharmacist before you begin.
Side by side02
What do the sources say about each ingredient?
Three of the six names tied to a MemoPryl sibling pack have a seizure note. None is confirmed for your bottle, and no amounts are printed.
| Name | Note |
|---|---|
| Ginkgo biloba leaf | Seizures reported in predisposed people (MSK, Ginkgo) |
| N-acetyl L-carnitine | Carnitine can cause seizures in people with seizure disorders (NIH ODS, Carnitine) |
| St. John's wort | Can weaken some seizure drugs (NCCIH, St. John's Wort safety) |
| Other three | Cited sources do not address seizures |
The reverse03
Can seizure medicine change carnitine levels?
Yes. NIH says valproic acid, phenobarbital, phenytoin and carbamazepine reduce blood carnitine levels (NIH ODS, Carnitine).
That is a reason to name every supplement to your prescriber. They may want to know about carnitine in a memory capsule.
Do not change a seizure medicine dose on your own. If a supplement is in the picture, your prescriber decides what to do about it.

What should I ask a pharmacist about seizures and supplements?
Show the bottle and say you have a seizure history or take seizure medicine.
- Does any ingredient on this panel affect seizure risk?
- Can it change how my seizure medicine works?
- Is there a safer plan for my focus goals?
Write the answers on the bottle list you bring to your next visit. The medicine guide lists more cautions.
The two MemoPryl bottle images disagree on capsule count and show no ingredient panel, so read the bottle you receive before any of these questions.
FAQ05
Seizure and supplement questions
Is ginkgo safe for someone with epilepsy?
Ask the prescriber first. Memorial Sloan Kettering reports seizures with ginkgo in predisposed people, so a seizure history is a reason to check before any ginkgo product.
Can carnitine cause seizures?
According to NIH, carnitine supplements can cause seizures in people with seizure disorders. Anyone with a seizure history should ask a doctor or pharmacist before using it.
Should I tell my neurologist about my supplements?
Yes, every one. List the name, label amounts and start date. Some supplements change how medicines work, and your neurologist cannot check what is left unsaid.
Do seizure risks apply to every brand of these supplements?
The cautions come from the ingredient itself, so they apply wherever it appears. For MemoPryl, the six names come from a sibling pack, so confirm the real ingredient list on your bottle.
