Read the amount of the active ingredient
The 2024 trial used a product containing 90% alpha-GPC: 350 mg and 700 mg of product supplied 315 mg and 630 mg of alpha-GPC. Product weight and active ingredient weight can therefore differ. Neither studied dose is a general recommendation. 1
What does the European safety assessment cover?
EFSA’s 2026 opinion assessed a specified soy-derived ingredient at up to 203.7 mg alpha-GPC daily, equivalent to 82.5 mg choline, and found it safe under the proposed conditions. This safety assessment does not establish a cognitive benefit or endorse every product and dose. 2
