DOES IT WORK?
Results vary. Rapeseed (canola) lecithin is a solid soy-free alternative for people avoiding soy. Contains phosphatidylcholine, a source of choline. In supplements, it's primarily used as an emulsifier to improve absorption of fat-soluble ingredients. The choline content provides modest brain support but usually isn't enough to meet daily needs on its own.
