HelloPharmacist Scorecard of DMAE 250 mg by Thompson

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 23, 2026

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: DMAE (deanol), at 250 mg per capsule. DMAE is a compound thought to support brain function and acetylcholine levels — a chemical messenger in your nervous system.

The capsule also includes inactive ingredients — gelatin, cellulose, silica, and magnesium stearate — which serve as the capsule material and binders.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Deanol's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: cognitive function.
  • We looked for evidence on: Cognitive function, Attention deficit-hyperactivity disorder (ADHD), Alzheimer disease, memory, mental clarity, brain health.
  • The closest evidence on file: Deanol is rated "Likely Ineffective" for Alzheimer disease (Natural Medicines).
  • Also on file: Deanol is rated "Insufficient Reliable Evidence To Rate" for Attention deficit-hyperactivity disorder (ADHD), Cognitive function.

The evidence we have on DMAE's effectiveness is limited. For Alzheimer disease and tardive dyskinesia (involuntary movements sometimes caused by antipsychotic medications), DMAE is rated likely ineffective.

For aging skin, ADHD, and athletic performance, there isn't enough reliable evidence to rate whether it works. If you're considering it for any of these uses, that's worth discussing with your doctor.

The evidence, ingredient by ingredient Deanol

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

DMAE is generally well tolerated by some adults, but evidence is limited and side effects can occur. The most common ones reported orally are abdominal cramps and pain, diarrhea, drowsiness, nausea, and vomiting.

Less commonly, it's been linked to headache, insomnia, confusion, constipation, skin rash, and in people with psychiatric conditions, mood changes or worsening of schizophrenia symptoms — especially at doses above 1000 mg daily. Safety data during pregnancy is not on file.

The data advises against use while breastfeeding because there isn't enough safety information. If you're pregnant or nursing, talk with your doctor or pharmacist before taking this supplement.

Side effects, ingredient by ingredient Deanol

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Deanol.
  • The most serious interaction on file is rated Minor.
  • For scale: 219 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 DMAE, check with your doctor or pharmacist if you take anticholinergic drugs (for overactive bladder, certain Parkinson's symptoms, or glaucoma) or cholinergic drugs (which enhance nerve-muscle signals). DMAE may theoretically weaken the first group and strengthen the second, both at Minor severity.

No interactions are documented for other medication types, but no interactions documented is not the same as proof none exist.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

DMAE 250 mg may appeal to someone curious about brain-support supplements, but the evidence for its effectiveness is weak or absent for most common uses. If you take anticholinergic or cholinergic medications — common for bladder issues, Parkinson's, or myasthenia gravis — check with your doctor or pharmacist before adding this product.

It's also worth discussing side effects and timing with your healthcare provider.

DMAE 250 mg by Thompson: Common Questions

Does DMAE 250 mg by Thompson interact with any medications?
Yes. Based on its ingredients, DMAE 250 mg has a known interaction with 219 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
DMAE 250 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is DMAE, and what is it supposed to do?
DMAE (deanol) is a compound thought to support brain function by raising acetylcholine, a chemical messenger in your nervous system. The evidence for what it actually does in your body is limited — it's rated likely ineffective for Alzheimer disease and tardive dyskinesia, and we don't have enough data to know if it helps with ADHD, aging skin, or athletic performance.
What are the most common side effects?
The most common side effects reported are abdominal cramps and pain, diarrhea, drowsiness, nausea, and vomiting. A small number of people also report headache, insomnia, or confusion. At higher doses (above 1000 mg daily), mood changes have been reported, especially in people with psychiatric conditions.
Can I take this while I'm pregnant or breastfeeding?
Safety data during pregnancy isn't on file, so there isn't enough information to know either way — talk with your doctor or pharmacist for personalized advice. The available data advises against use while breastfeeding because safety information is too limited.
Does this product have any fillers or other ingredients I should know about?
The capsule contains gelatin, cellulose, silica, and magnesium stearate — these are inactive ingredients that make up the capsule and help hold it together. The only active ingredient is DMAE at 250 mg.
Why do I need to check my medications before taking this?
DMAE may theoretically change how anticholinergic and cholinergic drugs work in your body — both common medication types. Even though these interactions are listed as Minor severity, it's worth confirming with your doctor or pharmacist that this product won't affect your specific prescriptions.
