Deanol Drug Interactions, Uses, Effectiveness, Safety & More
What is this page for?
First and foremost: how Deanol interacts with medications. The heart of this page is the interaction list — every drug Deanol is known to interact with, and how serious each one is.
But these pages have grown well beyond that into a full monograph — what Deanol is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

Add one medicationDeanol Drug Interactions: The Bottom Line
From the HelloPharmacist Editorial Team · Updated July 2026Based on the available evidence, the overall risk of a clinically significant Deanol drug interaction appears low for most people. None of the listed interactions are rated major or moderate, and every one of them is classed as minor with weak supporting evidence.
The only concerns in the data involve medications that work on acetylcholine, a chemical messenger in the body. Because deanol is thought to raise acetylcholine levels, it could in theory blunt anticholinergic drugs or add to the effects and side effects of cholinergic drugs. Even here, the documentation grades suggest these effects have not been shown to occur in people, so we see them as points of awareness rather than proven problems.
The long list of interacting medications may look worrying, but it mostly reflects these two theoretical concerns applied across many individual drugs. In other words, the same predicted effect on acetylcholine accounts for nearly the whole list, and it has not been confirmed in humans. A long list here does not mean each combination is actually harmful.

What Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Where This Data Comes From
- Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

Deanol: Uses, Safety & Side Effects
Deanol (DMAE) is a compound related to choline that is marketed for memory, focus, and mood, but solid human evidence for most of these uses is limited or mixed. It can cause side effects in some people, and it should be avoided in pregnancy and breastfeeding because its safety is not established. Talk to your pharmacist or doctor before trying it.

- Part used
- Synthetic or naturally occurring compound (not a plant part)
- Common forms
- Capsules, tablets, liquid drops, powder; also found in skin creams
- Memory and focus
- Mood and mental clarity
- ADHD-type symptoms
- Skin firmness (topical)
- General brain health
Popular and traditional uses — not proof it works. See “Uses & effectiveness” below for the evidence.
May be tolerated by some adults but evidence is limited and side effects can occur.

Overview
Deanol is a chemical compound also known as DMAE (2-dimethylaminoethanol). It is closely related to choline, a nutrient your body uses to make brain chemicals. Small amounts of deanol occur naturally in the body and in some foods such as fish.
It is sold as a dietary supplement in capsules, tablets, liquids, and powders, and it is sometimes added to skin creams. People take it hoping to sharpen memory, improve focus, lift mood, or support healthy aging. In the past, a prescription form was studied for attention and movement problems, but it is no longer widely available as a medicine in most places.
How it works
Deanol is a precursor in the body's pathways related to choline and acetylcholine, a brain chemical involved in memory and learning. The popular theory is that taking deanol could raise acetylcholine levels and support brain function.
In reality, scientists are not certain how much deanol actually increases acetylcholine in the human brain, and some research suggests its effects on the brain are limited. Much of the support for its proposed mechanism comes from laboratory and animal studies, which do not always carry over to people.
Does Deanol work?
How to read these evidence grades
Natural Medicines’ 7-point scale. We show each rating’s label word-for-word.
Likely Ineffective Alzheimer disease
Oral deanol does not appear to improve memory in individuals with Alzheimer disease.
Likely Ineffective Tardive dyskinesia
Oral deanol does not improve symptoms of tardive dyskinesia.
Also studied for 5 conditions — evidence insufficient to rate
Insufficient Reliable Evidence To Rate Aging skin
Although there has been interest in using topical deanol for aging skin, there is insufficient reliable information about the clinical effects of deanol for this purpose.
Insufficient Reliable Evidence To Rate Athletic performance
Oral deanol has only been evaluated in combination with other ingredients; its effect when used alone is unclear.
Insufficient Reliable Evidence To Rate Attention deficit-hyperactivity disorder (ADHD)
It is unclear if oral deanol is beneficial in children with ADHD.
Insufficient Reliable Evidence To Rate Autism spectrum disorder
Although there has been interest in using oral deanol for autism spectrum disorder, there is insufficient reliable information about the clinical effects of deanol for this purpose.
Insufficient Reliable Evidence To Rate Cognitive function
Although there has been interest in using oral deanol to improve cognitive function, there is insufficient reliable information about the clinical effects of deanol for this purpose.

Where Natural Medicines hasn’t rated a use, HelloPharmacist’s pharmacists may add their own reviewed rating and evidence (each such entry is labeled). This is educational information, not medical advice — talk with your pharmacist or doctor before starting, stopping, or changing a supplement.
Safety & precautions
For many healthy adults, short-term use may be tolerated, but the long-term safety of deanol is not well established. People with seizure disorders, bipolar disorder, or other mental health conditions should be especially cautious, as stimulating supplements can sometimes worsen symptoms.
Pregnancy: Avoid deanol. Some animal studies have raised concerns about effects on development, and there is not enough human safety data.
Breastfeeding: Avoid use, since it is unknown whether deanol passes into breast milk or is safe for the baby.
Always check with your pharmacist or doctor before starting deanol, especially if you take other medicines or have a health condition.
Side effects
Reported side effects of deanol include headache, trouble sleeping, vivid dreams, muscle tension, irritability, restlessness, and constipation. Some people notice mild stimulation or jitteriness.
Less commonly, it may cause increased blood pressure or worsen mood swings in sensitive people. If you notice confusion, severe agitation, muscle stiffness, or any concerning reaction, stop using it and contact a healthcare provider.

Adverse-effects data: Natural Medicines, Therapeutic Research Center
Dosing
There is no official or standardized dose of deanol for supplement use. Products vary widely in strength and form, so the amount in one brand may differ from another.
The safest approach is to follow the directions on the product label and not exceed them. Because evidence is limited, start low if your provider approves, and check with your pharmacist or doctor to decide whether deanol is appropriate for you.
