Can a common supplement protect the liver during cancer treatment?
The effect of N-acetyl-l-cysteine (NAC) on liver toxicity and clinical outcome after hematopoietic stem cell transplantation

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.
Surprising Findings
NAC normalized liver enzymes in 30% of patients with severe pre-treatment elevations, yet didn’t reduce death rates.
Common sense says fixing liver damage should improve survival—but here, the biomarker improved without changing outcomes, suggesting bilirubin is a marker, not a driver, of mortality.
Practical Takeaways
Patients undergoing busulphan-based transplant should ask their oncologist about prophylactic NAC (100 mg/kg twice daily) to reduce liver enzyme spikes and jaundice risk.

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.
