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.

Case-Control Study

Human

The study gave patients NAC while they were getting a strong chemotherapy drug called busulphan, and found that their liver enzymes went down and returned to normal in many cases — exactly what the claim says.

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.

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.
