What the Science Says

Choline is an essential nutrient found in foods like eggs and meat that the body uses to build cell membranes and produce the neurotransmitter acetylcholine. One provided study examined choline alfoscerate (a choline compound) for mild-to-moderate cognitive impairment, reporting benefits in multiple RCTs and meta-analyses. Another small pilot study found oral choline reduced working memory-related brain activation in postmenopausal women, though what that means practically is unclear.

What It Doesn't Do

Not proven to prevent Alzheimer's disease in healthy adults. No evidence from these studies it boosts athletic performance. Don't expect dramatic memory improvements from standard supplement doses. The cognitive research is mostly in people with existing impairment, not healthy adults.

Evidence-Based Benefits

Red Flags to Watch For

Most cognitive research is in people with existing impairment — benefits in healthy adults are unproven from these studies
Several papers provided are about choline-containing drug compounds (diazoxide choline, tiomolibdate choline) for rare diseases — not standard choline supplements
One study found prenatal choline imbalance disrupted dopamine signaling in offspring — excess supplementation during pregnancy should be discussed with a doctor
Some papers tagged to this search (microplastics, battery research) are irrelevant to choline supplementation, suggesting the evidence base is thin
