HelloPharmacist Scorecard of Memory Maintenance by Vitamer Laboratories

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients. Blueberry powder is a concentrated form of the whole fruit, traditionally used for eye and brain health.

Sunflower phosphatidylserine is a naturally occurring compound found in cell membranes — it's often extracted from plant sources and studied for cognitive support. The capsule itself is made from vegetable material, with inactive ingredients including dicalcium phosphate, cellulose, magnesium stearate, and silica to hold everything together.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Memory and brain health support.
  • We looked for evidence on: Age-related cognitive decline, Cognitive function, Dementia, Alzheimer disease, Memory, Neural function — and 1 related terms.
  • The strongest evidence on file: Phosphatidylserine is rated "Possibly Effective" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Phosphatidylserine is rated "Possibly Effective" for Alzheimer disease.
  • Also on file: Phosphatidylserine is rated "Insufficient Reliable Evidence To Rate" for Cognitive function, Dementia.

Phosphatidylserine is possibly effective for age-related cognitive decline and Alzheimer disease according to the evidence we hold. For blueberry, the data on cognitive decline is insufficient to rate — we don't have strong enough evidence either way.

Neither ingredient has established effectiveness for anxiety, athletic performance, or heart health, though both have been studied for some of these uses.

The evidence, ingredient by ingredient Blueberry Phosphatidylserine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Blueberry is generally well tolerated as a food and is rated likely safe in pregnancy and lactation. However, concentrated blueberry supplements haven't been well studied in pregnancy or high-dose extracts while breastfeeding — the safety data advises caution.

Freeze-dried blueberries can cause constipation, diarrhea, nausea, or vomiting; one trial found that over a quarter of participants stopped taking high-dose freeze-dried blueberries in the first week due to stomach upset. Phosphatidylserine is generally well tolerated, though long-term safety isn't fully established.

It can cause flatulence, stomach upset, headache, insomnia (especially at higher doses around 600 mg), and nausea — gastrointestinal side effects are more likely at doses of 200–300 mg per day. The safety data advises against use during pregnancy and breastfeeding.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Phosphatidylserine, Blueberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 307 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you start this product, double-check these medication types: anticholinergic drugs and cholinergic drugs (Moderate interactions with phosphatidylserine), then antidiabetes medications, flurbiprofen, and buspirone (Minor interactions with blueberry).

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Memory Maintenance is worth considering if you're looking to support cognitive function — phosphatidylserine has decent evidence for age-related memory concerns. Talk with your pharmacist or doctor before starting if you take medications for bladder control, Parkinson's disease, myasthenia gravis, Alzheimer's disease, blood sugar management, or pain relief.

If you have a sensitive stomach, start low and watch for nausea or digestive upset.

General Statements

We guarantee our supplements for potency and purity

Human brain cell membranes are highly enriched with phosphatidylserine (PS). PS levels in these tissues ensure the membrane's fluidity and structure, thus their function. Nerve cells, in particular, depend on healthy membrane function for normal neurotransmitter metabolism and nerve signal transmission. Maintaining brain PS levels can be associated with normal and efficient signalling processes, efficient brain glucose consumption, and other biological pathways that are crucial to ensure normal and healthy cognitive and mental functions.

Supports brain health

Sunflower Phosphatidylserine Complex2 drug types · 219 drugs

Anticholinergic Drugs

Theoretically, phosphatidylserine might decrease the effectiveness anticholinergic drugs.
Phosphatidylserine is thought to increase acetylcholine levels, which could theoretically interfere with the activity of anticholinergic agents.

Likelihood Possible Evidence B
Cholinergic Drugs

Theoretically, phosphatidylserine might have additive effects with cholinergic drugs.
Phosphatidylserine is thought to increase acetylcholine levels, which could theoretically lead to additive cholinergic effects when used with cholinergic drugs.

Likelihood Possible Evidence B

organic Blueberry powder3 drug types · 88 drugs

Antidiabetes Drugs

Theoretically, blueberries or blueberry leaf extracts might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vitro research suggests that blueberry and/or blueberry leaf extracts can lower blood glucose levels.

Likelihood Unlikely Evidence D
Buspirone (Buspar)

Theoretically, blueberry juice might increase blood levels of buspirone.
In vitro research shows that blueberry juice can inhibit the metabolism of buspirone, possibly by inhibiting cytochrome P450 3A (CYP3A) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking buspirone hydrochloride 10 mg does not significantly affect the concentration or clearance of buspirone.

Likelihood Unlikely Evidence B
Flurbiprofen (Ansaid, Others)

Theoretically, blueberry juice might increase blood levels of flurbiprofen.
In vitro research shows that blueberry juice can inhibit the metabolism of flurbiprofen, possibly by inhibiting cytochrome P450 2C9 (CYP2C9) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking flurbiprofen 100 mg does not significantly affect the concentration or clearance of flurbiprofen.

Memory Maintenance by Vitamer Laboratories: Common Questions

Does Memory Maintenance by Vitamer Laboratories interact with any medications?
Yes. Based on its ingredients, Memory Maintenance has a known interaction with 307 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Memory Maintenance contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant or breastfeeding?
Blueberry is rated likely safe in pregnancy and lactation, but the concentrated supplements haven't been well studied — talk with your doctor about whether this product makes sense for you. Phosphatidylserine is a different story: the safety data advises against it during pregnancy and breastfeeding. It's best to skip this product if you're pregnant or nursing, or get personalized advice from your pharmacist.
Is blueberry actually in this product?
Yes — it's listed as organic blueberry powder, one of the two active ingredients. The other is sunflower phosphatidylserine, a compound from plant cell membranes.
Will this help my memory?
Phosphatidylserine is possibly effective for age-related memory loss and Alzheimer disease based on the evidence we hold. For blueberry and general brain fog, the data isn't strong enough to say — we have insufficient evidence to rate either way.
What side effects should I watch for?
Blueberry can cause constipation, diarrhea, nausea, or vomiting — particularly if you're taking a high-dose freeze-dried form. Phosphatidylserine may cause stomach upset, flatulence, headache, insomnia (worse at higher doses), or nausea. Both are generally well tolerated, but start low if you have a sensitive stomach.
Why is there a warning about anticholinergic drugs?
Phosphatidylserine in this product increases acetylcholine levels in your body, which can interfere with how anticholinergic medications work — drugs like benztropine or oxybutynin. That's why you need to check your exact medications with your pharmacist first.
