Consumer advice
If you want liver support, pick a single well-studied ingredient rather than a "detox" bundle: NAC and milk thistle (standardized for silymarin content) have the best evidence among this lineup. Skip products promising to "detoxify" or "cleanse" — your liver does that job already, and no pill accelerates it meaningfully. Check the actual label for milligram doses of the active compound (e.g., silymarin content, not just "milk thistle") before buying, since this page doesn't show per-product dosing. If budget matters, a generic NAC or milk thistle extract from a reputable commodity brand will deliver similar active ingredients for a fraction of Thorne's price; pay the Thorne premium only if you specifically value their third-party testing (NSF Certified for Sport) or phytosome absorption technology.
