HelloPharmacist Scorecard of DMAE Bitartrate 250 mg by Intensive Nutrition

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-bitartrate (dimethylaminoethanol bitartrate), which is thought to raise levels of acetylcholine, a chemical messenger in the brain. The capsule also contains microcrystalline cellulose and magnesium stearate as inactive ingredients (binders and flow agents).

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Deanol product and its label doesn't state a use — see Deanol's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for DMAE-bitartrate is limited. It is rated likely ineffective for Alzheimer disease and tardive dyskinesia (involuntary movement disorder).

For aging skin, athletic performance, and ADHD, there is insufficient reliable evidence to rate 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 is generally well tolerated orally, but side effects can occur and the evidence base is limited. The most common adverse effects reported are abdominal cramps, abdominal pain, diarrhea, drowsiness, nausea, and vomiting.

Other reported effects include headache, insomnia, overstimulation, lucid dreams, confusion, depression, and hypomania. At doses above 1,000 mg daily, mood changes (depression and hypomania) have been reported, especially in people with psychiatric conditions; doses of 1,500 mg daily have been linked to worsening schizophrenic symptoms in patients with chronic schizophrenia.

Pregnancy safety data is not on file. Because safety during breastfeeding is unknown, the data advises against use 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 this product, check with your pharmacist or doctor if you take anticholinergic drugs (common for urinary incontinence, eye problems, or movement disorders) or cholinergic drugs (used for myasthenia gravis, Alzheimer disease, or glaucoma), since deanol may decrease the effect of one group and increase the effect of the other.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

DMAE-bitartrate may be worth considering if you're curious about brain health and are not taking anticholinergic or cholinergic medications, but the evidence for its effectiveness is limited and side effects do occur. If you take any psychiatric medications, drugs for urinary or eye issues, or movement-disorder treatments, talk with your doctor or pharmacist before starting.

The same goes if you're pregnant or breastfeeding—your healthcare provider can help you weigh the risks and benefits for your situation.
