Can alcohol affect how ferrous sulfate and folic acid work?

Alcohol interferes with how folate is absorbed. It may also cause the kidneys to remove too much folate. Folic acid levels may be lower in more than 50% of those who drink alcohol. People who abuse alcohol often have diets low in folate. Alcohol may be associated with lower risks of iron deficiency and iron deficiency anemia, but too much alcohol may lead to a higher risk of iron overload.
