A double-blind experiment was used in which 14 subjects drank 240 mL per day of orange juice fortified with 1000 IU of vitamin D and 12 subjects drank 240 mL per day of unfortified orange juice. Concentration levels were recorded at the beginning of the experiment and again at the end of 12 weeks. The accompanying data, based on the results of the study, provide the before and after serum 25(OH)D concentrations in the blood, in nanomoles per liter (nmo / L), for the group that drank the fortified juice.Data table Data table for before and after serum 25(OH)D concentrations in the blood Before After Before After Full data set 171.9 197.1 143.8 214.9 54.8 159.5 45.8 127.6 120.4 170.3 151.6 205.8 111.3 143.6 87.5 128.6 130.5 201.6 172.1 259.2 47.5 70.9 173.9 193.7 156.3 222.1 64.3 135.5
