HelloPharmacist Scorecard of DMAE Dimethylaminoethanol Bitartrate 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, supplying 351 mg of DMAE per tablet. DMAE (dimethylaminoethanol) is thought to support acetylcholine production in the brain and has been studied for cognitive function and aging-related concerns.

The tablet also contains inactive ingredients — stearic acid, dibasic calcium phosphate, magnesium stearate, modified cellulose gum, and silica — which are fillers and binders that give the tablet its form.

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: Enhances mental concentration and focus.
  • We looked for evidence on: Attention deficit-hyperactivity disorder (ADHD), Cognitive function, Memory, 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. It's rated likely ineffective for Alzheimer disease and tardive dyskinesia (involuntary movement disorder).

For other uses — aging skin, athletic performance, and ADHD — the evidence isn't established well enough to rate it either way. If you're considering this product for one of those purposes, talk with your doctor or pharmacist about whether the current evidence supports trying it.

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

It's also been reported to cause headache, insomnia, confusion, and mood changes — especially in people with psychiatric conditions or when doses exceed 1000 mg daily. At 1500 mg daily, it's been linked to worsening schizophrenia symptoms in people with that diagnosis.

There isn't enough safety data to recommend DMAE during pregnancy. The safety data advises against use while breastfeeding.

If you're pregnant, breastfeeding, or have a psychiatric condition, talk with your doctor or pharmacist before 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 you take DMAE, check with your doctor or pharmacist if you're on anticholinergic drugs (used for overactive bladder, muscle spasms, and other conditions) or cholinergic drugs (used for myasthenia gravis and certain eye problems). DMAE may decrease or increase how these medications work.

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 be worth considering if you're looking for a cognitive support supplement and don't have a psychiatric history, but the evidence for its benefits is weak or absent for most uses. Anyone taking anticholinergic or cholinergic medications should check their exact drug names with their doctor or pharmacist before starting.

Pregnant women, those breastfeeding, and people with mood or psychiatric conditions should talk it over with their healthcare provider first.
