cow (milk from Jersey and Guernsey cows contains more riboflavin than
Holstein milk). Summer milk generally contains slighly higher levels of
riboflavin than winter milk. Interspecies variations in concentration are also

value for pasteurized goats’ milk (0.13 mg per 100 g) is lower; human milk
contains 0.03 mg per 100 g. Dairy products also contain significant amounts
