Vitamin E acts as a powerful antioxidant. In MASH, excess fat in liver cells drives a build-up of reactive molecules called free radicals, creating oxidative stress that damages liver tissue and fuels inflammation. Vitamin E helps neutralize these free radicals, protecting liver cells from this oxidative injury.
As oxidative stress eases, liver inflammation may decrease, and some patients see improvement in certain liver enzyme levels. In selected patients, Vitamin E has also been associated with improvement in liver histology (the appearance of liver tissue under the microscope).
For patients with MASH, these antioxidant effects can support treatment goals such as reduced liver inflammation and better liver enzyme levels. Vitamin E is not used on its own — providers pair it with a balanced diet, regular physical activity, and periodic monitoring, such as Liver Function Tests (LFTs), to track response.
