If you take vitamins for a long time, it may further increase the chance of developing tumor diseases of the rectal and colon systems. If you have underlying liver disease, such as viral hepatitis, autoimmune hepatitis, or alcoholic hepatitis caused by long-term alcohol consumption, it is recommended that you take as little medication as possible, and pay attention to preventing colds and flu, avoiding alcohol consumption, taking more rest, not staying up late, and not straining. In addition, it is not recommended to take vitamins together with other drugs, which may cause further drug interactions.
