The liver does a remarkable amount of quiet work, so Priority One has assembled the nutrients and botanicals traditionally chosen to support it. Milk thistle leads the botanical side, joined by lipotropic nutrients such as choline and inositol that take part in normal fat metabolism. Chlorella, a single-celled green algae, brings a whole-food option, and a fresh plant extract formula offers a different botanical profile. Some blends also include glandular concentrates, so the range spans both vegetarian and animal-derived choices. Whether used as a seasonal reset or a steady part of the week, these formulas are made to the same NSF-certified standards as everything else the company produces.
