Each capsule delivers 300mg of **Milk Thistle Extract** standardized to 80% silymarin — giving you 240mg of the active flavonoids responsible for liver-protective effects. That puts a single capsule right in the middle of the 150–600mg clinical range. The label suggests 1–3 capsules daily, so at the full 3-capsule dose you're getting 900mg, well above what most studies used.
**Dandelion** (100mg) and **Artichoke** (50mg) round out the formula as traditional liver-support herbs. Both are dosed well below their studied ranges (500–1,500mg for dandelion, 300–640mg for artichoke), so they're contributing minimally at these amounts. Artichoke has moderate clinical evidence for bile flow and digestion, but you'd need several times this dose to match the research.
The milk thistle itself uses a standard extract rather than a phytosome form, which means lower absorption of the key compound silybin. If your main goal is liver support, the silymarin dose is solid — but getting more silybin into your bloodstream would require a phytosome-bound form.
