Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Fish oil capsule
Fish oil capsule (specially manufactured for the study)
One capsule per day for 4 weeks (28 days). The fish oil group receives a daily supplement of one fish oil capsule, specially manufactured for the present study by Peter Möller (now Möller's, Nydalen, Norway). The fish oil capsules are aimed to contain a dose of cholecalciferol identical to the dose already found in the multivitamin tablets by analysis in an independent laboratory (AS Vitas, Oslo, Norway), and similar doses of vitamin A. In addition, the fish oil capsule contains vitamin E and n-3 fatty acids.
Multivitamin tablet
Multivitamin tablet of type: Vitaplex ABCD
One tablet per day for 4 weeks (28 days). The multivitamin group receives a daily supplement of one multivitamin tablet of type Vitaplex ABCD (Cederroth AS, Revetal, Norway), a common vitamin supplement sold in grocery stores in Norway. In addition to 10 micrograms (400 IU) of cholecalciferol,the multivitamin tablet contains vitamin A and the water-soluble vitamins: B1, B2, B6, Niacin, pantothenic acid, and vitamin C.
