WHAT IT DOES
A concentrated phosphatidylcholine supplement that delivers high-potency choline for brain and liver support.
🏆
2
DOES IT WORK?
Good pick. This is a 75% standardized phosphatidylcholine extract, meaning it's more concentrated than standard lecithin (which is only 15-25% PC). You get more actual choline per serving. PC supports brain function through acetylcholine production, protects liver cells, and maintains cell membrane integrity. The higher concentration means better value and lower pill burden. Solid evidence for liver health and brain function.
