MemoPryl Ingredients List: Six Names, Zero Amounts
The MemoPryl ingredients list has six names and no amounts: phosphatidylserine, ginkgo biloba leaf, N-acetyl L-carnitine, St. John's wort, brahmi (bacopa) and L-glutamine. They come from a sibling pack, not from either bottle photo. Confirm the list on the bottle you receive before you swallow a capsule.

What ingredients are in MemoPryl capsules?
Six names are tied to MemoPryl: phosphatidylserine, ginkgo biloba leaf, N-acetyl L-carnitine HCl, St. John's wort, brahmi (Bacopa monnieri) and L-glutamine. None has a printed amount.
They come from the seller's notes on a sibling pack. Neither bottle photo shows an ingredient line, and the two photos differ on name, count and claims. So the list is a lead, and your bottle is the proof.
Check: open the Supplement Facts panel on arrival. If it names other ingredients, the bottle wins.

The seller's notes name these six "on a sibling MemoPryl pack from the same listing family" and says to confirm the current bottle. No bottle image we have shows a Supplement Facts panel, and the order of a panel is unknown, so this order comes from the seller's notes, not the label.
Where can I read about each ingredient?
Each name has its own page, with the studies, the amounts researchers used and the cautions. Open the one you worry about most.

Why does the list show no milligrams?
Because no Supplement Facts panel was supplied. Without that panel there is no serving size, no capsules a day and no amount per capsule.
A name tells you what a product may contain. Only a number tells you how much, and that decides both benefit and risk.
Studied amounts are research figures, not advice (Kato-Kataoka 2010, soy PS trial) (DeKosky 2008, GEM trial, JAMA).

See packsWhich MemoPryl ingredient needs the most care?
St. John's wort, by a wide margin. It can weaken many prescription medicines, so the name alone is a reason to ask your pharmacist first (NCCIH, St. John's Wort safety).
Ginkgo comes second: FDA notes that ginkgo, warfarin, aspirin and vitamin E can each thin the blood (FDA, Mixing Meds and Supplements).
| Name | Sold for | Main caution |
|---|---|---|
| St. John's wort | Mood | Weakens many medicines; serotonin syndrome risk with some antidepressants (MedlinePlus, Serotonin syndrome) |
| Ginkgo biloba leaf | Memory, focus | Bleeding risk; seizures reported in people at risk (MSK, Ginkgo) |
| Phosphatidylserine | Memory | Stomach upset, gas, insomnia, headache (Cleveland Clinic, Phosphatidyl.) |
| N-acetyl L-carnitine HCl | Mental energy | Nausea and stomach upset at high amounts (NIH ODS, Carnitine) |
| Brahmi (bacopa) | Memory | Usually mild: nausea, cramps, loose stools (LiverTox, Bacopa monnieri) |
| L-glutamine | Energy, recovery | Swelling, stomach symptoms, headache in some studies (MSK, Glutamine) |
Do not stop or change a prescription because of a supplement. Ask your doctor or pharmacist before you start, and say so before any surgery.
How do I check the ingredients on my own bottle?
Read the Supplement Facts panel first, then the other-ingredients line, then the warnings. Four checks cover most of it.
- Every name on the panel has an amount in mg or mcg.
- The other-ingredients line names the capsule shell and any allergen.
- The warnings line mentions medicines, pregnancy and surgery.
FDA has warned that some products hold drugs the label never lists (FDA, Hidden Ingredients). Reading the panel costs nothing. The longer question list is in the pharmacist guide.

Questions about MemoPryl ingredients
What is the active ingredient in MemoPryl?
No single active ingredient is named on the bottle images. Six names are tied to a sibling pack: phosphatidylserine, ginkgo, N-acetyl L-carnitine, St. John's wort, bacopa and L-glutamine. Confirm which, if any, are on your own bottle.
Does MemoPryl contain St. John's wort?
St. John's wort is named in the seller's notes on a sibling pack, but not on either bottle photo. Treat it as possible, and ask a pharmacist first if you take any medicine.
Is MemoPryl made from natural ingredients?
A brand badge says natural ingredients, but it names no certifier. Natural does not mean safe, and St. John's wort is the classic example (NCCIH, Using Supplements Wisely). Read the panel and ask a pharmacist about your own medicines.
Are there fillers or allergens in MemoPryl capsules?
The other-ingredients line is not printed on any image we hold, so the shell and fillers are unknown. Badges claim gluten free and dairy free, but no certificate is shown. Read the line on your bottle.
Which MemoPryl ingredient is the riskiest?
St. John's wort carries the widest interaction risk, followed by ginkgo for bleeding. Both are named only on a sibling pack, so check your bottle first. Keep taking prescribed medicine and ask your pharmacist.
Are the MemoPryl ingredients lab tested?
No lab report is published. Two lot references exist, but they are seller references, not proof.
