MemoPryl Proprietary Blend: Why Do the Amounts Matter?
A MemoPryl proprietary blend would list the six ingredients under one combined weight, hiding each amount. Whether one applies is unknown, because no label panel was found. Check your bottle: separate amounts let you and a pharmacist compare each name against research doses.

Basics01
What is a MemoPryl proprietary blend?
A MemoPryl proprietary blend, if one applies, is a group of ingredients listed with a single total instead of separate amounts. US label rules allow this, listing parts by weight order (21 CFR 101.36, supplement labels).
No panel was found, so we cannot say if one applies.
Why it matters02
Why do ingredient amounts matter?
Amounts matter because research results depend on dose, and a blend hides it. Without amounts you cannot compare with trials.
| Label line | Group | Per serving | % DV | Amount used in research | Evidence |
|---|---|---|---|---|---|
| Phosphatidylserine | Nutrients and amino acids | Not published | Not known | Typical supplement intake is cited as 80 to 500 mg a day; trials were small and mostly under 6 months (FDA, phosphatidylserine claim) (ADDF, phosphatidylserine) | Limited and preliminary; the FDA allowed only qualified claims |
| Ginkgo biloba leaf | Herbal extracts | Not published | Not known | 240 mg a day of a specific dry extract in the European monograph for mild dementia (NCCIH, Ginkgo) (Cochrane, Ginkgo (PEARLS)) (EMA/HMPC, Ginkgo monograph) (MSK, Ginkgo) | Inconsistent; large trials found no prevention of dementia |
| N-Acetyl L-Carnitine HCl | Nutrients and amino acids | Not published | Not known | 1,000 to 3,000 mg a day in dementia trials (Cochrane, acetyl-L-carnitine) (NIH ODS, Carnitine) | No evidence of benefit in the Cochrane review of dementia trials |
| St. John's wort | Herbal extracts | Not published | Not known | Depression trials used standardized extracts for 4 to 12 weeks; not studied for memory (NCCIH, St. John's wort) (NCCIH, St. John's wort in depth) (Cochrane, St. John's wort) (NCCIH, herb-drug interactions) | Researched for mild to moderate depression rather than memory |
| Brahmi / Bacopa monnieri | Herbal extracts | Not published | Not known | 300 to 450 mg a day of extract for 12 weeks in small trials (Pase 2012, Bacopa review) (Bacopa meta-analysis 2014) (LiverTox, Bacopa) (Merck Manual, Bacopa) | Small, early trials; modest and inconsistent memory results |
| L-glutamine | Nutrients and amino acids | Not published | Not known | No studied dose for memory (Ogden 2020, L-glutamine tolerance) | No evidence for memory in the sources found |
Your bottle03
How do you tell if your label uses a blend?
You tell by looking for a line reading "blend" with one total and the names beneath it. Separate amounts per name means no blend.
Separate amounts
- You can compare with research
- A pharmacist can check interactions
One blend total
- Dose of each name is hidden
- Small amounts can hide in the total

What should you do if amounts are hidden?
If amounts are hidden, ask the order desk for the breakdown and show the label to a pharmacist. Call Order desk.
Keep taking prescribed medicine. A third-party test mark can help (USP Verified Mark). See supplement facts and testing and quality.

FAQ05
Blend questions
Does a blend mean MemoPryl is underdosed?
Not necessarily, but a blend cannot show it either way. Without separate amounts you cannot tell whether any name reaches the amounts used in research.
Is a proprietary blend legal on a supplement label?
Yes, label rules allow blends to list a total weight with names in descending order (21 CFR 101.36, supplement labels). Legal does not mean helpful for comparing doses.
Can I ask a company for the breakdown of a blend?
You can ask. A company may decline, but the request is reasonable. Ask the order desk and keep the reply in writing.
