Top 7 liver supplements, tested and ranked. I spent around $500 across five months. Here's what actually moved my bloodwork.

Milk thistle is the first thing every fatty liver guide recommends, and it deserves to be. I tried one of the most advertised versions for four weeks at the recommended serving. ALT after: 63. That number isn't an argument against milk thistle. It's an argument against buying it alone. Read what's actually in the bottle: milk thistle, then seven more herbs working the same side of the problem. Nothing rebuilds glutathione, nothing keeps bile moving, nothing helps clear fat. One lane, eight names on the front. And on its own it is the ingredient readers complain about most — loose stools, an unhappy stomach, and a rash for anyone who reacts to ragweed or daisies, since it comes from the same family. It was never the wrong ingredient. It was the wrong bottle.

I bought these because my Facebook feed kept pushing them. The pitch: your liver's "drainage system" gets congested, and these drops flush it out. I took the recommended dose for four weeks. ALT after: 64. Identical to baseline. The mechanism is the problem. Lymphatic congestion has nothing to do with why hepatocytes leak under oxidative stress. "Drainage" feels like action, but it doesn't map to the cell biology of liver enzyme elevation.

Thorne is one of the most credible names in the category and their quality control is not the problem. What one ingredient can do on its own is. Two capsules got me to 1,000mg of NAC and, on plain-capsule absorption math, probably under 100mg into circulation. ALT moved from 56 to 53. NAC feeds glutathione, and that is the entire job description. Nothing here moves bile, nothing here handles fat, nothing here does what a milk thistle extract does. One lane of four, bought at full price.

If you've spent ten minutes on YouTube in the last year, you've seen this product. The ingredient list is not the problem: milk thistle, dandelion, turmeric, artichoke, beetroot, NAC. Read as a list it is close to right. Now try to find out how much of any of it you are getting. The amounts are not printed, and a list without numbers beside it is a story, not a formula. What I can see is what isn't there at all — no choline, so nothing helps the liver move fat, and no glutathione. After four weeks my ALT was 62. The label is recognizable. The results aren't. This is the bottle that changed the question I was asking: not which ingredients are on the front, but how many of them are printed with a number beside them.

The logic seems obvious: if my liver is short on glutathione, just take glutathione. I tried NOW Foods at 250mg daily for four weeks. ALT after: 63. No change. The problem is the molecule, not the brand. Glutathione is a tripeptide that gets broken back into amino acids in the stomach before it ever reaches the liver. NAC is the precursor your cells use to build glutathione inside the cell, where it is actually needed. Feed the factory and supply the finished molecule by a route that never goes through the stomach, and the same job gets covered from both ends. Swallow the finished molecule on its own and it gets covered from neither.

And even with the delivery solved, this is one job out of four. Glutathione is the cell's own defence, and there is nothing else in this bottle: no precursor to keep it topped up, nothing keeping bile moving, nothing helping the liver clear fat. Fifteen to twenty-two dollars made it the cheapest thing I tested and the one that changed the least, which is this whole list in one line. A liver does not have one problem, so one ingredient cannot be one answer.

This is the one I expected to be writing up as the winner. Ritual Labs built its name on a formula people genuinely talked about, and I ordered it on that reputation without thinking twice. Then I read the bottle. It has been rebuilt since the version that earned all that goodwill — still three real ingredients, still printed honestly, just aimed at a narrower slice of the work than the label people remember. Two capsules daily for four weeks. ALT after: 57. Three points: more than anything below it managed, and a long way from what I sat down expecting. Bile is missing from it entirely, and no amount of any of the other three covers a pathway that isn't in the bottle. It keeps second place because of what it used to be, not because of what is in the jar today.
