Silymarin is poorly water-soluble. In standard extract form, your digestive system breaks it down before it has any opportunity to reach the liver. The majority of what you swallow is eliminated before it arrives. This is why people take milk thistle for months and feel nothing — the compound is real, but the delivery fails.
Syll Restore uses phospholipid binding — the same absorption technology European pharmaceutical companies developed decades ago. Silymarin is bound to phospholipids, the same fats that make up your cell membranes. Your body absorbs them the way it absorbs food. The result is a form that reaches your liver at up to 4.6 times the concentration of standard extract.
Most supplements on the shelf skip this step entirely. It costs more. There's no regulatory pressure to do it. So they sell the cheap version and let you conclude that milk thistle doesn't work.
