Alpha-GPC is a choline-containing compound derived from soy or sunflower lecithin, used as a source of choline that crosses into the brain more readily than some other choline forms.

Why it’s used

Taken to support memory and cognitive function, and sometimes used before exercise on the theory it supports acetylcholine availability.

What the evidence is for

supporting memory measures in older adults with cognitive decline.

What the evidence says

A 2023 systematic review and meta-analysis of seven randomized trials and one cohort study found that alpha-GPC, alone or combined with the drug donepezil, was associated with better scores on cognition, function, and behavior measures in patients with adult-onset cognitive impairment linked to cerebrovascular injury, compared with placebo or other treatments. This is clinical-outcome evidence in a patient population with diagnosed neurological/cognitive disorders, not simply age-related decline, and several of the pooled trials combined alpha-GPC with a prescription cholinesterase inhibitor rather than testing it alone. The second cited study examined physical and psychomotor performance in healthy young men and does not address memory or older adults with cognitive decline, so it does not contribute evidence to this specific claim.

Dose studied

400–1200 mg — range used across clinical trials in cognitive decline populations.

Context

Trials in cognitive-decline populations have generally used doses in the range of several hundred to about 1,200 mg per day for weeks to months; results do not necessarily generalize to healthy adults.
