Benefit Evidence
Research sources
Brain health (2)
- A multicentre trial to evaluate the efficacy and tolerability of alpha-glycerylphosphorylcholine versus cytosine diphosphocholine in patients with vascular dementia
PubMed ID: 1916007
Clinical improvements in dementia patients support brain-health effects, tempered by open-study design.
- Effects of egg yolk choline intake on cognitive functions and plasma choline levels in healthy middle-aged and older Japanese: a randomized double-blinded placebo-controlled parallel-group study
PubMed ID: 37340479
RCT evidence of cognitive benefit and increased plasma choline in older adults supports a role in brain health.
Memory (2)
- A multicentre trial to evaluate the efficacy and tolerability of alpha-glycerylphosphorylcholine versus cytosine diphosphocholine in patients with vascular dementia
PubMed ID: 1916007
Multicenter clinical trial in vascular dementia showed symptomatic cognitive/memory improvement versus active comparator, but study was open and effect sizes not fully reported.
- Effects of egg yolk choline intake on cognitive functions and plasma choline levels in healthy middle-aged and older Japanese: a randomized double-blinded placebo-controlled parallel-group study
PubMed ID: 37340479
Double-blind RCT in middle-aged/older adults: egg-yolk choline (contains α‑GPC) produced statistically significant improvements in verbal memory.
