HelloPharmacist Scorecard of DMAE 351 mg by Source Naturals

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 1 of its 1 active ingredient.
  • “DMAE” is listed as a grouped ingredient — the label gives one combined amount (130 mg) without saying how much of each component you get.

This product contains one active ingredient: DMAE bitartrate (also called deanol), at 351 mg per tablet. DMAE is a naturally occurring compound thought to support brain chemistry by increasing acetylcholine, a neurotransmitter involved in memory and focus.

The tablet also contains several inactive ingredients — microcrystalline cellulose, stearic acid, modified cellulose gum, hydroxypropyl methylcellulose, magnesium stearate, and silica — which serve as binders, thickeners, and flow agents to hold the tablet together.

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: supports mental concentration.
  • We looked for evidence on: Cognitive function, Attention deficit-hyperactivity disorder (ADHD), focus, mental clarity, brain health.
  • The closest evidence on file: Deanol is rated "Insufficient Reliable Evidence To Rate" for Attention deficit-hyperactivity disorder (ADHD) (Natural Medicines).
  • Also on file: Deanol is rated "Insufficient Reliable Evidence To Rate" for Cognitive function.

The evidence for DMAE's effectiveness is limited. For Alzheimer disease, research rates it likely ineffective.

For tardive dyskinesia (involuntary movement disorder), the evidence also rates it likely ineffective. For aging skin, ADHD, and athletic performance, we hold insufficient reliable evidence to rate whether it works — meaning the research available isn't robust enough to say either way.

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, but side effects do occur. The most common ones are abdominal cramps, abdominal pain, diarrhea, drowsiness, nausea, and vomiting.

Other reported effects include constipation, headache, insomnia, overstimulation, confusion, and lucid dreams. At higher doses — above 1,000 mg daily — mood changes including depression and hypomania have been reported in people with psychiatric conditions.

There is not enough safety data for pregnancy, and some animal research raises concern; the safety data advises against use during pregnancy. For breastfeeding, safety is unknown, so it is best to avoid while breastfeeding.

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 taking DMAE, check with your doctor or pharmacist if you take anticholinergic drugs (medications that block acetylcholine, such as certain antihistamines or bladder-control medicines) or cholinergic drugs (such as glaucoma drops or some neurological medications) — DMAE may interfere with how these work. If you have a history of psychiatric illness, mood changes at higher doses have been reported, so a conversation with your provider is especially important.

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 may appeal to someone looking for cognitive support, but the evidence that it actually works for Alzheimer disease or common uses like ADHD is weak or absent. If you take anticholinergic or cholinergic medications, this product is not a good fit without clearing it first with your doctor or pharmacist.

Pregnant or breastfeeding? The safety data advises against it — talk with your doctor or pharmacist before considering it.

Yes. Based on its ingredients, DMAE 351 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 351 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 that's thought to increase acetylcholine, a brain chemical involved in memory and focus. It's sometimes marketed for cognitive support, though the evidence for it actually working is limited.
Does DMAE work for Alzheimer disease or ADHD?
For Alzheimer disease, research rates DMAE likely ineffective. For ADHD and athletic performance, we don't have enough reliable evidence to say whether it works or doesn't.
What are the most common side effects?
The most common side effects are abdominal cramps, abdominal pain, diarrhea, drowsiness, nausea, and vomiting. Other people have reported headache, insomnia, or sleep changes.
Is DMAE safe during pregnancy or breastfeeding?
No. The safety data advises against use during pregnancy because animal research raises some concern. For breastfeeding, there isn't enough data to know it's safe, so it's best to avoid it — talk with your doctor or pharmacist for personalized guidance.
Why do I need to check my medications before taking DMAE?
DMAE affects how your body uses acetylcholine, which interferes with medications that either block acetylcholine (anticholinergics like some bladder or allergy drugs) or boost it (cholinergics like glaucoma drops). Your doctor or pharmacist can see if any of yours are affected.
