This liver support formula is built around **Milk Thistle Extract** at 300mg standardized to 80% silymarin, placing you right in the middle of the 150–600mg clinical range studied for liver protection. That’s a solid daily dose for supporting your liver’s natural defenses against oxidative stress.

The supporting cast includes **Dandelion Root**, **Artichoke Leaf**, **Turmeric**, and **Ginger** — all traditional liver and digestive herbs. **Piperine** (black pepper extract) at 5mg is included to boost absorption of the turmeric. However, the turmeric itself is only 25mg, a fraction of the 500mg minimum studied in clinical research, so the piperine has very little to work with here.

The main limitation is that every ingredient besides milk thistle is dosed well below its clinical range — dandelion at 20% of its studied minimum, artichoke at 17%, and turmeric at 5%. You’re essentially getting a well-dosed milk thistle supplement with trace amounts of supporting herbs.
