What is in the capsule
MemoPryl Ingredients: Six Names and No Amounts Printed
MemoPryl ingredients, as named on a sibling pack, are phosphatidylserine, ginkgo biloba leaf, N-acetyl L-carnitine HCl, St. John's wort, brahmi (Bacopa monnieri) and L-glutamine. No bottle image prints an amount for any of them, and the six are unconfirmed for the bottle you receive. Confirm the list on your bottle.

The six names01
What are the MemoPryl ingredients?
Six ingredients are tied to MemoPryl: phosphatidylserine, ginkgo biloba leaf, N-acetyl L-carnitine HCl, St. John's wort, brahmi (Bacopa monnieri) and L-glutamine. They are named on a sibling MemoPryl pack from the same listing family.
That is a lead, not a label. Each card opens a write-up with the studies and cautions.

Unconfirmed02
Are these ingredients really in the bottle I will receive?
Not confirmed. The six names come from a different pack, and the two bottle images we hold disagree with each other on capsule count and claims.
If your bottle prints a different list, trust the bottle. The label page shows both bottles word for word.
- 1PhosphatidylserineIn the seller's notes · no printed amount
- 2Ginkgo biloba LeafIn the seller's notes · no printed amount
- 3N-Acetyl L-Carnitine HClIn the seller's notes · no printed amount
- 4St. John's WortIn the seller's notes · no printed amount
- 5Brahmi / Bacopa monnieriIn the seller's notes · no printed amount
- 6L-GlutamineIn the seller's notes · no printed amount
According to the seller's notes, these six appear "on a sibling MemoPryl pack from the same listing family", and the notes say to confirm the current bottle. None of our bottle images shows a Supplement Facts panel, so the panel order is unknown; the order here follows the seller's notes, not the label.
Amounts03
How much of each MemoPryl ingredient is in a capsule?
Nobody outside the brand can say. No image we have prints a milligram figure, so we do not print one either.
What we can show is the range used in studies. Those ranges are for the studied products, not for MemoPryl. Phosphatidylserine was tested at 100 mg or 300 mg a day in one small trial (Kato-Kataoka 2010, soy PS trial). Ginkgo extract was tested at 120 mg twice a day in the GEM trial (DeKosky 2008, GEM trial, JAMA). Bacopa extract is typically 300 to 600 mg a day (LiverTox, Bacopa monnieri).

Medicine cautions04
Which MemoPryl ingredients can clash with medicines?
Two of the six carry real interaction risks: St. John's wort and ginkgo. Ask your doctor or pharmacist before you start, and keep taking your prescribed medicine.
St. John's wort can weaken many medicines, including antidepressants, birth control pills, warfarin and some HIV, seizure and heart drugs (NCCIH, St. John's Wort safety). With some antidepressants it may cause serotonin-related side effects (MedlinePlus, Serotonin syndrome).
Ginkgo, warfarin, aspirin and vitamin E can each thin the blood, so combining them may raise bleeding risk (FDA, Mixing Meds and Supplements).
Say you take a supplement before surgery, a dental procedure or any new prescription. See St. John's wort and ginkgo for detail.

See packsEvidence05
Do the MemoPryl ingredients help memory?
The evidence is mixed and thin. No study has tested MemoPryl itself, and the single ingredients have results that range from a small signal to none.
The GEM trial of more than 3,000 older adults found no drop in dementia with ginkgo (NCCIH, Ginkgo). NIH's liver database says bacopa is not shown effective for any disease in adequately controlled trials (LiverTox, Bacopa monnieri). A 2003 Cochrane review did not justify routine use of acetyl-L-carnitine in dementia (NIH ODS, Carnitine).
Phosphatidylserine has an FDA claim only with a "very limited and preliminary" warning (FDA letter, PS health claim). St. John's wort was studied for low mood, not memory (NCCIH, St. John's Wort in depth). L-glutamine is not described as a memory supplement (MSK, Glutamine).
Your bottle06
How do I check the ingredients on my MemoPryl bottle?
Read the Supplement Facts panel and the other-ingredients line. Compare the names with the six above, then ask about anything that does not match.
- Look for an amount beside every ingredient.
- Look for St. John's wort and ginkgo by name.
- Show the bottle to your pharmacist.
FDA warns that some supplements hold ingredients missing from the label, which is one more reason to read closely and report problems (FDA, Hidden Ingredients). Natural does not mean safe (NCCIH, Using Supplements Wisely).
For dosing, see how to take the capsules.
FAQ07
MemoPryl ingredients: quick answers
Does MemoPryl contain St. John's wort?
St. John's wort is one of six names tied to MemoPryl on a sibling pack, but it is not confirmed for your bottle. It can weaken many medicines. Check the printed list and ask your pharmacist before you take it.
Is there ginkgo in MemoPryl?
Ginkgo biloba leaf is named on a sibling pack, not on either bottle image we hold. Ginkgo may raise bleeding risk with blood thinners and aspirin. Read your bottle and ask a clinician if you take either.
Is brahmi the same as bacopa in MemoPryl?
Usually yes. Brahmi is the Ayurvedic name for Bacopa monnieri, but the name is also used for gotu kola, so check the Latin name on the label. The sibling pack names Bacopa monnieri.
Is MemoPryl a proprietary blend?
We cannot tell. No panel has been supplied, so we do not know if the ingredients are listed with separate amounts or grouped in a blend. A blend would hide each amount, which makes comparison with studies harder.
