title: [Change of relative bioavailability of riboflavin by the fluid intake (author's transl)].
abstract: Administration of 6,7-dimethyl-9-(D-1-ribityl)-isoalloxazine (riboflavin) solution (30 mg/200 ml) dissolved in a fruit juice to 5 volunteers resulted in increased relative bioavailability between 156 and 246% compared to the intake with water. The reason should be the delayed gastric emptying rate due to the osmotic pressure and the acidity of the juice.
