DMAE (Dimethylaminoethanol)
DMAE is a naturally occurring compound and precursor to acetylcholine that supports mental clarity, focus, and skin health. It is valued for its mild stimulant properties and potential to improve attention and reduce age-related cognitive decline.
Benefits
What is DMAE (Dimethylaminoethanol)?
DMAE (dimethylaminoethanol, also known as deanol) is an organic compound naturally produced in the brain in small amounts and found in fatty fish. It is a precursor to choline and, subsequently, acetylcholine - the neurotransmitter essential for memory, learning, and muscle contraction.
DMAE gained popularity in the 1960s and 1970s when it was sold as a prescription drug (Deaner/Deanol) for learning and behavioural disorders in children. While it was withdrawn from prescription use due to insufficient evidence for those indications, it remains widely available as a dietary supplement and is a common ingredient in nootropic stacks and skincare products.
Users typically report improved mental clarity, mild stimulation, better concentration, and more vivid dreams. DMAE is also one of the few nootropics with significant cosmetic applications - it is used in topical formulations for its skin-firming and anti-ageing properties.
- Acetylcholine precursor: DMAE is methylated to choline in the liver, which is then used to synthesise acetylcholine in the brain, supporting memory and cognitive function.
- Membrane stabilisation: DMAE is incorporated into phosphatidyl-DMAE (a structural analogue of phosphatidylcholine) in cell membranes, potentially improving membrane fluidity and neuronal signalling.
- Lipofuscin reduction: Some evidence suggests DMAE reduces the accumulation of lipofuscin (age pigment) in brain cells - a waste product associated with cellular ageing.
- Mild cholinergic stimulation: Enhances cholinergic tone in the brain, contributing to improved attention, alertness, and wakefulness.
- Antioxidant activity: Scavenges free radicals and protects cell membranes from oxidative damage.
- Typical dose: 100–300 mg per day (as DMAE bitartrate - the most common supplement form)
- For cognitive support: 150–300 mg daily
- Starting dose: 100 mg to assess tolerance, as some individuals are sensitive to cholinergic compounds
- Best taken: In the morning - may cause insomnia if taken late in the day
- Onset: Effects may take 2–3 weeks of consistent use to become fully noticeable
- Side effects: Possible headache, insomnia, muscle tension, or irritability - particularly at higher doses.
- Vivid dreams: Commonly reported, likely due to increased acetylcholine activity during REM sleep.
- Contraindications: Avoid with bipolar disorder, epilepsy, or schizophrenia - cholinergic compounds may exacerbate symptoms.
- Pregnancy: Not recommended - DMAE may interfere with foetal neural tube development.
- Drug interactions: May interact with anticholinergic medications and cholinesterase inhibitors (used for Alzheimer's disease).
Natural Sources & Forms
- Endogenous production: Produced in small amounts in the human brain
- Food sources: Fatty fish - especially sardines, anchovies, and salmon
- Supplements: Most commonly available as DMAE bitartrate in capsules or powder. Also found in many nootropic stack formulations.
