Folic Acid Supplementation Study (1999)
The folic acid supplementation study was a double blind placebo-controlled randomized trial. Healthy nonsmoking male subjects were recruited among the staff and students at the University of Kuopio. Exclusion criteria included regular intake of drugs, vitamins or antioxidants, obesity (BMI > 30 kg/m2), and severe diseases. Forty men were randomized to receive either placebo (microcrystalline cellulose) or 300 g folic acid (Foliren®) three times a day for 12 wk. All the subjects provided a written informed consent. The Research Ethics Committee of the University of Kuopio approved the study protocol.
This study was done and samples analyzed in co-operation with Department of Clinical Chemistry, Laboratory of Atherosclerosis Genetics, Tampere University Hospital, and University of Tampere, Medical School, Tampere, Finland (Professor Terho Lehtimäki and researchers Riikka Rontu and Päivi Hämelahti). Oy Verman Ab delivered supplements and partial funded this study.
