A choline-related compound sold as an oral supplement and skin-firming cream. Its best-supported effect is a modest, temporary firming of facial skin and softening of fine lines. Benefits for memory, focus, and longer life remain largely unproven. Inexpensive and easy to find, but overstimulation, disrupted sleep, headaches, and a pregnancy caution temper the enthusiasm.

Protocol

Oral Dose

100–300 mg/day

DMAE bitartrate; 100–200 mg daily typical for cognitive/mood use

Topical

~3% gel or cream

Leave-on facial application once daily for skin firming

Timing

Morning or early afternoon

Avoid dosing within ~6–8 hours of bedtime due to stimulating effect

Time to effect

Topical (immediate)

Within hours

Initial skin-tightening sensation

Topical (cumulative)

Weeks

Cosmetic firmness and fine-line changes over daily use

Oral (mood/cognition)

Subtle to none

Any effect variable; controlled trials found no reliable cognitive benefit

Benefits

Medium: Topical skin firming and reduction of fine lines

Low: Mood, motivation, and behavioral symptoms

Speculative: Cognitive enhancement and focus; antioxidant and anti-lipofuscin activity; longevity and lifespan; lucid dreaming and dream vividness

Contraindications

Pregnancy and breastfeeding

Epilepsy or seizure disorder

Bipolar disorder, active depression, or schizophrenia

Dementia (Alzheimer's, moderate-to-severe) for cognitive use

Key Interactions

Cholinesterase inhibitors (donepezil, rivastigmine, galantamine)

Anticholinergics (oxybutynin, benztropine, scopolamine)

Antihypertensives (ACE inhibitors, calcium channel blockers)

Antipsychotics

Over-the-counter stimulants (caffeine)

Cholinergic and choline-donor supplements (citicoline, alpha-GPC, choline bitartrate, huperzine A, centrophenoxine)

Risk & Side Effects

Medium: Central nervous system overstimulation; topical skin irritation and fibroblast toxicity

Low: Drowsiness and confusion in older adults with dementia; reproductive and developmental risk; seizure threshold and mood destabilization; blood pressure elevation

Speculative: Long-term and cumulative safety unknowns

Monitoring

Marker	Target	Why
Blood pressure	< 120/80 mmHg	DMAE can raise blood pressure; detects overstimulation
Resting heart rate	50–70 bpm	Stimulatory and cholinergic effects can shift heart rate
Serum choline (optional)	~7–20 µmol/L	Reflects choline-pathway status for cognitive use

Cadence: Baseline before starting, recheck at 1–2 weeks, then periodically every 3–6 months during continued use
