The short version
What is MemoPryl?
MemoPryl is a capsule dietary supplement marketed for concentration, focus and memory. The brand graphics name six ingredients, including phosphatidylserine, ginkgo and bacopa. Two bottle designs exist, holding 30 or 60 capsules, and no Supplement Facts panel was available.
MemoPryl is a capsule dietary supplement marketed for concentration, focus and memory. The brand's graphics name six ingredients, and the eBay seller that fills our orders lists two more.
Two bottle designs are in circulation. One says "Advanced Formula, By NutraVibe" with 60 capsules; the other says "Cognitive Support Formula" with 30 capsules, and that is the bottle on the live listing. Neither design's Supplement Facts panel was available to us, so this site never guesses an amount or a dose.

Why does St. John's wort in MemoPryl matter?
St. John's wort can make other medicines stop working, and NCCIH calls some of these interactions dangerous, sometimes life-threatening. It can weaken birth control pills, warfarin and digoxin, so ask your pharmacist before the first capsule if you take any prescription medicine.

Evidence check
Does MemoPryl work for memory?
No trial of MemoPryl has been published, so no result can be promised. Bacopa shows small memory effects at about 300 mg a day, but MemoPryl's amounts are not public, so that research cannot be matched to a dose.
No trial of MemoPryl has been published. Here is how strong the research is for its main ingredients on their own.
What the meter means for you
Bacopa has small memory effects at about 300 mg a day over three months (ADDF, Bacopa). Phosphatidylserine and acetyl-L-carnitine show slight or mixed results (ADDF, Phosphatidylserine) (NIH ODS, Carnitine). Ginkgo did not prevent dementia in large studies (NCCIH, Ginkgo). Without amounts on the label, nobody can say whether MemoPryl reaches those doses. How the formula is meant to work.
Step by step
MemoPryl dosage: how do you take it?
Take MemoPryl by the serving printed on your own bottle, with water and the same way each day, and do not go over it. Two labels exist and no Supplement Facts panel was seen, so this site states no number.

Avoid mix-ups
Is MemoPryl the same as metoprolol, or endorsed by a celebrity?
No and no. Metoprolol is a prescription blood pressure and heart drug with a similar sound, and MemoPryl is a supplement. No celebrity endorses MemoPryl, so never swap one for the other.
No and no. Metoprolol is a prescription blood pressure and heart drug, and no celebrity endorses MemoPryl.
Not metoprolol
Search engines pair the two names because they sound alike. MemoPryl is a supplement. Never swap one for the other, and tell your doctor which one you take.
No famous backers
Ads for memory products sometimes use celebrity faces without permission. MemoPryl has no celebrity link. Other sellers also use the MemoPryl name with different formulas, so match your bottle to the label shown here.

What is MemoPryl?
MemoPryl is a capsule dietary supplement marketed for focus, concentration and memory. The brand names phosphatidylserine, ginkgo, acetyl-L-carnitine, St. John's wort, bacopa and L-glutamine. It comes as capsules, 30 or 60 to a bottle.
What ingredients are in MemoPryl?
The brand names phosphatidylserine, ginkgo, acetyl-L-carnitine, St. John's wort, bacopa and L-glutamine, and huperzine A also appears. The amounts are not public, and two label versions exist. Check the label on the bottle you receive.
Is MemoPryl a scam or legit?
The bottle sold here comes from a live eBay listing with free shipping and 30-day seller-paid returns. Its weak points are missing amounts and two label versions. Many complaint pages concern other sellers using the same name.
Does MemoPryl really improve memory?
No trial of MemoPryl has been published, so no result can be promised. Bacopa shows small memory effects at about 300 mg a day (ADDF, Bacopa), but MemoPryl's amounts are not public.
Is MemoPryl safe?
Not for everyone without a check. St. John's wort weakens birth control, warfarin, some antidepressants and heart, HIV, transplant and seizure drugs (NCCIH, St. John's wort). Huperzine A can slow the heart rate. Ask your pharmacist first.
What are the side effects of MemoPryl?
Possible effects from its ingredients include stomach upset, dizziness, headache, trouble sleeping and sun sensitivity, plus a slower heart rate from huperzine A (ADDF, Huperzine A). Stop and call your doctor if you notice a problem.
Who should not take MemoPryl?
Adults under 18 should not take it, and anyone pregnant, nursing or trying to conceive should ask a doctor first. Ask a pharmacist first if you take any prescription medicine or a dementia drug, or have a slow heart rate or epilepsy.
Is MemoPryl FDA approved?
No. The FDA does not approve dietary supplements before they are sold (FDA, supplement questions). A brand badge mentions an FDA registered facility, which is a registration, not an approval (FDA, Approval myths).
How many MemoPryl capsules a day?
Follow the serving printed on your bottle. We have not seen a Supplement Facts panel for either version, so we do not state a number. Two label versions exist, so read the one on the bottle you receive.
