Dosage facts
What Are the MemoPryl Doses on the Label and in the Studies?
The MemoPryl doses are not published. No image or page we have shows an amount per ingredient, a serving size or directions. The brand says only "Adults, 18+ (follow the label)". Use the serving printed on your own bottle and never go above it. Research doses exist for single ingredients, not for this formula.

What are the MemoPryl doses on the label?
The short answer is zero published numbers. The MemoPryl doses for each ingredient, the serving size and the directions are not shown in any picture or page we have. That is true for both label versions.
The only instruction we can quote is on a brand graphic. It reads "Adults, 18+ (follow the label)". It gives no capsule count, no time of day and no length of use.
Some other websites print a serving for a product called MemoPryl. That product may use a different formula, so we do not borrow its numbers. Your own back panel is the only source that counts.
Which study doses sit behind the MemoPryl ingredients?
Five of the named ingredients have a dose range in the research we cite. The studies tested one ingredient at a time, not this formula.
- Phosphatidylserine: 80 to 500 mg a day, and most trials lasted under 6 months (ADDF, Phosphatidylserine).
- Bacopa (brahmi): usually 300 mg a day, within a range of 250 to 600 mg, for about 3 months (ADDF, Bacopa).
- Acetyl-L-carnitine: 1.5 to 3 g a day, for 3 to 12 months (NIH ODS, Carnitine).
- Alpha-GPC: 1,200 mg a day, in dementia trials only (ADDF, Alpha-GPC).
- Huperzine A: 200 to 400 mcg a day, in small dementia trials (ADDF, Huperzine A).
Ginkgo, St. John's wort and L-glutamine have no range in this list, because our sources do not give one for memory use.
Why do the MemoPryl doses stay unknown, and why does it matter?
A study effect belongs to a dose. If a capsule holds far less than the trial amount, the trial tells you little. If it holds more, the risk side changes.
MemoPryl names up to eight ingredients, six on brand graphics and two more from the eBay seller's list. Eight ingredients share each serving. Some may sit well below research levels. Only the printed panel can settle that.
A single blend total would hide each share. That is why we ask you to look for milligrams beside each name when your bottle arrives.

How long does one bottle last, whatever the MemoPryl doses are?
Use this rule: days of supply equal 30 capsules divided by the capsules your label counts as one day. The bottle on the live listing holds 30 capsules.
These are examples, not MemoPryl directions. If a label said 1 capsule a day, 30 divided by 1 gives 30 days. If it said 2, you get 15 days. If it said 3, you get 10 days.
Cost follows the same idea. A capsule costs about $1.30 ($39.00 divided by 30). Multiply that by your daily capsules for a cost per day. We do not print a daily figure, because the serving is not published.
What should you do if your bottle shows no directions?
Do not guess. A missing serving is a reason to stop and ask before the first capsule.
- Photograph the front and back panel.
- Check the inner seal under the cap.
- Message the eBay seller from your order, or call the order desk at +1 (302) 200-3480 if you ordered through it.
- Keep the bottle until you have an answer.
Never take two servings to catch up on a missed one. The brand graphic limits use to adults 18 and over, so do not give it to a teenager.
Who should check the MemoPryl doses with a pharmacist first?
Anyone who takes a prescription medicine. MemoPryl contains St. John's wort, which can weaken birth control pills, warfarin and many other drugs (NCCIH, St. John's wort). The amount does not need to be large for a pharmacist to want a look.
Bring the bottle and your full medicine list. Do not stop or change a prescription on your own. Pregnancy and breastfeeding are reasons to skip the product. Our side effects page lists the drug groups to check.

MemoPryl doses: common questions
How many MemoPryl capsules should I take a day?
The number on your own label. We have not seen a serving size for either version, so we state none. If your bottle has no directions, ask the seller before you start.
How many milligrams of each ingredient are in MemoPryl?
Unknown. No Supplement Facts panel was available to us, so we never print an amount. Look for milligrams or micrograms beside each name on your back panel.
Can I take more MemoPryl to see results faster?
No. More capsules do not speed anything up and raise the chance of side effects. The studies we cite used fixed daily doses over weeks or months.
What if I miss a MemoPryl dose?
Follow any missed-dose line on your label. With none, skip the missed one and go on at your usual time. Do not take two servings at once.
Do the study doses apply to MemoPryl?
Not directly. The trials tested single ingredients at known amounts. MemoPryl's amounts are not public, so those results cannot be carried over to the bottle.
Are there different MemoPryl doses on other websites?
Other sellers use the MemoPryl name, sometimes for different formulas. A serving printed on their page may not match the bottle sold here. Match the label first.
Our view: what can you rely on?
You can rely on one rule: the printed serving on your bottle. The MemoPryl doses are the biggest gap on this product, and no website can fill it for you. We will not guess a number.
The study ranges are context, not directions. This page is information, not medical advice. MemoPryl is a dietary supplement that is not FDA approved, as no supplement is. Talk to a doctor or pharmacist about any medical question.
