Drinking too much alcohol is known to damage the liver and pancreas which are vital to digestion and metabolism. It can also damage the lining of the intestinal tract and adversely affect the absorption of nutrients, leading to sub-clinical malnutrition. Regular heavy use of alcohol increases the body's need for the B-group vitamins, particularly thiamine, niacin, pyridoxine,folic acid and vitamins B12, A and C as well as the minerals zinc, magnesium and calcium. Alcohol affects availability, absorption and metabilism of nutrients.
