Can a common supplement protect the liver during cancer treatment?

Doctors gave a supplement called NAC to patients getting strong chemo before a bone marrow transplant to see if it helped their liver. It did help lower some liver damage signs, but didn't change survival or other big problems.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Researchers compare people who have a condition (cases) with similar people who do not (controls), looking back in time for differences in exposure. Useful but more prone to bias.

When people get a special type of bone marrow transplant, they take a strong drug called busulfan to wipe out their old blood cells. Giving them a common antioxidant called NAC at a high dose doesn’t change how busulfan works in the body, so it won’t mess up the treatment’s ability to kill bad cells.
When people get ready for a bone marrow transplant and take a special drug called busulfan, giving them a common supplement called NAC twice a day might help protect their liver — studies show their liver enzymes, which go up when the liver is stressed, often drop back to normal in about 1 in 3 patients who started with high levels.
Giving a common antioxidant called NAC to patients before a bone marrow transplant doesn't seem to make them any more or less likely to have serious complications like liver damage, rejection, or even death, compared to how patients did in the past without NAC.
NAC is a supplement that helps your liver make more of a natural cleaning chemical called glutathione, which helps your body get rid of toxins.
When people get a special type of bone marrow transplant, giving them a common supplement called NAC twice a day might help protect their liver — in one study, far fewer patients on NAC had high levels of a liver damage marker called bilirubin compared to those who didn’t get it.
