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), supplied at 351 mg per capsule. The remaining ingredients are inert fillers and capsule materials — gelatin, microcrystalline cellulose, hydroxypropyl methylcellulose, magnesium stearate, and silica — which help form and preserve the capsule but play no active role.

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: support mental concentration.
  • We looked for evidence on: Cognitive function, Attention deficit-hyperactivity disorder (ADHD), memory, focus, mental clarity.
  • 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 deanol in the uses studied is limited. For Alzheimer disease and tardive dyskinesia (a movement disorder), research rates it as likely ineffective.

For aging skin, ADHD, and athletic performance, the evidence is too thin for us to rate it either way — we simply don't hold enough reliable data. If you're considering this supplement for a specific reason, it's worth asking your doctor whether the research supports it for your particular goal.

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.

Deanol is generally well tolerated by some adults, but side effects do occur and the overall safety record is mixed. The most common adverse effects reported orally are abdominal cramps, abdominal pain, diarrhea, drowsiness, nausea, and vomiting.

At higher doses — above 1000 mg daily — deanol has been tied to mood changes including depression and hypomania, especially in people with existing psychiatric conditions. At 1500 mg daily, it has been reported to worsen schizophrenia symptoms in people with chronic schizophrenia.

Because of limited safety data and animal research that raises concern, deanol should be avoided during pregnancy. Safety data during breastfeeding is also too sparse — breastfeeding should be avoided while taking this product.

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 this product, check with your doctor or pharmacist if you're on anticholinergic drugs (such as those for overactive bladder or Parkinson's disease) or cholinergic drugs (such as those for myasthenia gravis). Both categories carry Minor-severity interaction risks with deanol's mechanism of action.

Even though these are Minor interactions, the underlying effect on acetylcholine means your healthcare provider should review your specific medications and current conditions.

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 support with memory or cognition, though the evidence for Alzheimer disease is weak. Because deanol affects acetylcholine, anyone on anticholinergic or cholinergic medications needs to check their specific drugs with their pharmacist or doctor before starting.

If you have a history of psychiatric conditions or are pregnant or breastfeeding, talk with your healthcare provider first — the safety data here is limited, and mood and neurological effects warrant personalized guidance.

DMAE 351 mg by Source Naturals: Common Questions

Does DMAE 351 mg by Source Naturals interact with any medications?
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, also called deanol, is a compound thought to raise acetylcholine levels in the brain. It's been studied for memory, aging skin, ADHD, and athletic performance, though the evidence is weak or absent for most of those uses.
Does this product actually work for Alzheimer disease or memory problems?
Research rates deanol as likely ineffective for Alzheimer disease. For ADHD and other memory or cognitive goals, the evidence is too thin for us to say either way — the data we hold simply isn't there to support a clear answer.
What are the most common side effects I might notice?
The most commonly reported side effects are abdominal cramps, abdominal pain, diarrhea, drowsiness, nausea, and vomiting. Some people also report headache, insomnia, or mood changes. If you notice any of these, stop and talk to your pharmacist or doctor.
Is it safe to take while pregnant or breastfeeding?
No — there isn't enough safety data for pregnancy or breastfeeding. Because animal research raises concern and some side effects involve mood and neurological function, deanol should be avoided in both cases. Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.
Can I take this if I have depression or a psychiatric condition?
At higher doses, deanol has been reported to worsen mood and even increase schizophrenia symptoms in people with those conditions. If you have depression, anxiety, bipolar disorder, schizophrenia, or any other psychiatric condition, check with your doctor or pharmacist before starting this product.
What are the inactive ingredients in this capsule?
The inactive ingredients are gelatin, microcrystalline cellulose, hydroxypropyl methylcellulose, magnesium stearate, and silica — all standard capsule fillers and binders.
