Fatty liver is caused by the accumulation of excessive fat in liver cells, resulting in changes in liver function. Fatty liver patients can take some vitamins in moderation, including vitamins A, B, C and D. These can improve fat metabolism and affect fat absorption, but they cannot play a fundamental role in the treatment of fatty liver. The most effective treatment for fatty liver should be etiological treatment. First of all, if it is alcoholic fatty liver, you should first avoid alcohol and cooperate with medication. If it is non-alcoholic fatty liver, see if the patient is obese, if it is caused by obesity, or diabetes or hyperlipidemia, we should control blood sugar and blood lipids, increase aerobic exercise in moderation, and at the same time control a high-fat diet, and take in a variety of vitamins from food, including fresh vegetables and fruits, which contain a large number of vitamins, so there is no need to make special efforts to supplement various vitamins.
