HelloPharmacist Scorecard of DMAE Bitartrate 150 mg by Life Extension

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 11, 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: dimethylaminoethanol (deanol), supplied at 150 mg per capsule. The supplement also includes microcrystalline cellulose, cellulose, and stearate as inactive ingredients to form and fill the capsule.

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: memory, focus, and brain health.
  • We looked for evidence on: Cognitive function, Attention deficit-hyperactivity disorder (ADHD), Alzheimer disease, mental clarity, mood support, neurotransmitter synthesis.
  • 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 for deanol is limited. For Alzheimer disease and tardive dyskinesia (involuntary movement disorder), studies rate it likely ineffective.

For aging skin, ADHD, and athletic performance, there isn't enough reliable evidence to establish whether it works.

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 seems to be well tolerated by some adults, but the safety data is limited and side effects do occur. Common side effects include abdominal cramps, abdominal pain, diarrhea, drowsiness, nausea, and vomiting.

At higher doses — over 1000 mg daily — it has been reported to cause mood changes like depression and hypomania, particularly in people with psychiatric conditions. Doses of 1500 mg daily have been reported to increase schizophrenic symptoms in patients with chronic schizophrenia.

The safety data isn't sufficient during pregnancy, so it's best avoided then. There isn't enough safety information for breastfeeding, so it's also best avoided while nursing.

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.

Check your exact medications if you take anticholinergic drugs (like those for overactive bladder or certain motion sickness remedies) or cholinergic drugs (such as those for myasthenia gravis or certain types of glaucoma) — deanol may affect how they work. Both interactions are minor, but worth verifying with the search tool on this page.

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.

Deanol (DMAE) is one to check before you start, especially if you take anticholinergic or cholinergic medications. The evidence for its effectiveness is weak to absent for most conditions.

If you take any prescription medications or have a psychiatric condition, talk with your pharmacist before using this product.
