HelloPharmacist Scorecard of DMAE 2-Dimethylaminoethanol Bitartrate by OL Olympian Labs Incorporated

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 (2-dimethylaminoethanol bitartrate), a compound thought to support acetylcholine, a chemical messenger in the brain. The remaining ingredients—microcrystalline cellulose, rice flour, ascorbyl palmitate, and silica—are inactive excipients used to form the capsule and improve shelf life.

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 and focus, brain health.
  • We looked for evidence on: Cognitive function, Attention deficit-hyperactivity disorder (ADHD), Alzheimer disease, mental clarity, ADHD-type symptoms.
  • 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 DMAE is limited. It is rated likely ineffective for Alzheimer disease and tardive dyskinesia (a movement disorder).

For aging skin, ADHD, and athletic performance, the evidence isn't established well enough in our data to say whether it works or not.

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 can happen. The most common ones reported are abdominal cramps, abdominal pain, diarrhea, drowsiness, nausea, and vomiting.

Other reported effects include constipation, headache, insomnia, overstimulation, confusion, and mood changes. At higher doses (over 1000 mg daily), mood changes including depression and hypomania have been reported, and in people with schizophrenia, it has been linked to worsening symptoms.

The safety data advises against DMAE during pregnancy. There isn't enough data to know whether it's safe during breastfeeding—talk with your doctor or pharmacist before using it if you're 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 (used for urinary or bowel issues, motion sickness, or certain eye conditions) or cholinergic drugs (like those for myasthenia gravis or some types of glaucoma). Both categories have Minor interactions with DMAE.

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 curious about brain health, but the evidence for most of its claimed uses isn't solid, and it does carry Minor interactions with common medication types. If you take anticholinergic or cholinergic drugs, you'll want to check your exact medications with your doctor or pharmacist before starting.

If you're pregnant or breastfeeding, the safety data suggests avoiding it.
