WHAT IT DOES
A soy-free phospholipid source that supports brain and liver health while helping your supplements mix properly.

DOES IT WORK?
Sunflower lecithin is rich in phosphatidylcholine, which your brain and liver actually need. As a standalone supplement, it's decent for choline intake and liver support. In most products though, it's there as an emulsifier at doses too low to matter therapeutically. When dosed properly (1-3g), it's a legit choline source.
