WHAT IT DOES
A fat-based delivery system that helps your body actually absorb poorly soluble ingredients.

DOES IT WORK?
Phospholipid complexes (like Phytosome technology) wrap active ingredients in phospholipids to dramatically improve absorption. The research on curcumin and silymarin phytosomes is solid, showing 5-10x better bioavailability. The complex itself isn't the star, but it makes the star perform way better.

Mechanism of Action
Phospholipids (primarily phosphatidylcholine) form complexes with active compounds, creating amphiphilic structures that cross intestinal membranes more easily. This dramatically improves the bioavailability of poorly absorbed ingredients.
