How much vitamin b does wheat flour have?

Wheat flour contains several B vitamins, including thiamine (B1), riboflavin (B2), niacin (B3), and folate (B9). The exact amounts can vary based on the type of wheat and the processing of the flour, but whole wheat flour generally has higher levels of these vitamins compared to refined flour. For example, one cup of whole wheat flour may provide about 10% of the daily value for several B vitamins. However, enriched white flour is often fortified with additional B vitamins, particularly niacin and folic acid.
