Is MemoPryl a nootropic supplement?
In everyday talk, yes. A MemoPryl nootropic supplement is a capsule sold to support focus and memory. In plain terms, it is a dietary supplement. The word "nootropic" is a marketing label, so this site uses plain terms such as dietary supplement and memory support.
That matters for what you can expect. MemoPryl is not a drug. It is not a treatment for memory loss, dementia or Alzheimer's disease, and its labels do not claim to be. The FDA does not approve supplements before they go on sale (FDA, Supplement Q&A).
There are two label versions: a 60-capsule "Advanced Formula" by NutraVibe and a 30-capsule "Cognitive Support Formula". The live listing sells the 30-capsule one.
What do the 8 ingredients in this MemoPryl nootropic supplement do?
They come from four ideas about the brain, plus one amino acid that sits outside all four. Public research describes each one alone. None of it tested MemoPryl itself.
- A membrane compound: phosphatidylserine, found in brain cell membranes.
- Three herbs: bacopa (brahmi), ginkgo leaf and St. John's wort. Only bacopa has memory trials that lean positive, and the effects are small.
- Carnitine: N-acetyl L-carnitine HCl, linked to cell energy.
- Choline helpers: alpha-GPC and huperzine A, listed by the eBay seller only.
- L-glutamine: a common amino acid, described by MSKCC for cancer care and surgery, not memory (MSKCC, Glutamine).
How strong is the evidence for each MemoPryl nootropic ingredient?
Weak to small. Our editorial meter scores each ingredient alone for memory support, from 0 to 5. The whole formula gets no score, because it has no trial.
Bacopa scores 2 of 5, from small trials at about 300 mg a day for 3 months (ADDF, Bacopa). Phosphatidylserine, acetyl-L-carnitine and huperzine A score 1.5 each. Ginkgo scores 1, because it did not lower dementia risk in large studies, including one of 3,000 or more adults aged 75 and over (NCCIH, Ginkgo). St. John's wort scores 0 for memory, since it is studied for low mood (NCCIH, St. John's wort).
Two more facts help. Alpha-GPC has no studies in healthy people (ADDF, Alpha-GPC). Huperzine A did not help 84 healthy military personnel (ADDF, Huperzine A).

What do the claims on a MemoPryl nootropic supplement really mean?
The two labels print six claims between them. The 60-capsule bottle says Supports Concentration, Supports Brain Energy and Supports Productivity. The 30-capsule bottle says Supports Focus, Optimized Memory and Improves Mental Clarity.
Each ends with an asterisk. That marks a structure-function statement, the kind a supplement may print without FDA review, provided it makes no disease claim. The FTC still expects health claims to rest on competent and reliable scientific evidence (FTC, Health claims).
Read a line like "Supports Focus" as marketing, not as a finding about the capsules. Productivity and mental clarity were never measured in the studies we cite.
Who should skip a nootropic supplement like MemoPryl?
Several groups should not start without a doctor or pharmacist, and some should skip it.
- People under 18, and anyone pregnant, breastfeeding or trying to conceive.
- Anyone on a prescription. St. John's wort can weaken birth control, warfarin, some antidepressants, and heart, HIV, transplant and seizure drugs (NCCIH, St. John's wort).
- People on donepezil-type dementia drugs, or with a slow heart rate, because of huperzine A.
- People with epilepsy, because carnitine has been linked to seizures in people with seizure disorders (NIH ODS, Carnitine).

When is a doctor visit better than a nootropic supplement?
When memory changes disrupt daily life, get worse, or worry the people around you. Some causes are treatable, including medicine side effects, low vitamin B1 or B12, and depression (MedlinePlus, Memory loss).
The Alzheimer's Association lists warning signs, such as new trouble planning or handling money, and losing track of dates or where you are (Alzheimer's Association, 10 signs). NCCIH advises against putting off a visit for a supplement (NCCIH, Supplements for cognition).
Sudden confusion, trouble speaking, numbness or weakness on one side can be a stroke. Call 911 (CDC, Stroke signs).

MemoPryl nootropic supplement: common questions
What is a nootropic?
It is a popular word for products sold to support thinking, memory or focus. It is a marketing label, not a medical category. MemoPryl is a dietary supplement.
Does the MemoPryl nootropic supplement improve memory?
No trial of the formula has been published. Some ingredients show small memory effects alone at known doses, but MemoPryl's amounts are not public, so those results cannot be carried over.
Is MemoPryl a nootropic like a prescription brain drug?
No. It is a supplement. One ingredient, huperzine A, works much like prescription Alzheimer's drugs, which is why it needs a medicine check.
Can MemoPryl treat dementia or Alzheimer's?
No. Supplements have not been shown to prevent or treat these conditions. Talk to the treating doctor before any supplement.
Is there caffeine in MemoPryl?
None of the eight named ingredients is caffeine. The brain energy claim seems to lean on acetyl-L-carnitine, and no study measured an energy change from MemoPryl.
How should I test a nootropic supplement like MemoPryl?
Read the label, check your medicines, score two simple measures each day and decide before day 30, inside the return window.
Our view: is MemoPryl a sensible nootropic supplement to try?
The MemoPryl nootropic supplement can be a reasonable test for a healthy adult who takes no prescription medicine and accepts that amounts are unknown. The case against it is also clear: small evidence, no formula trial and a St. John's wort interaction list that matters more than the claims.
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.
