: Plasma homocysteine level and megaloblastic anemia status are two factors that can affect the quality of life of patients with multiple sclerosis (MS). We conducted this study to determine the effect of vitamin B12 and folic acid supplementation on serum homocysteine, megaloblastic anemia status and quality of life of patients with MS. A total of 50 patients with relapsing remitting multiple sclerosis (RRMS) included in this study which divided into 2 groups. The vitamin group received 5 mg folic acid tablet daily and 3 doses of vitamin B12 (1,000 mcg) injection and the other group received placebo and normal saline injection (same doses). The quality of life was measured by using Multiple Sclerosis Quality of Life-54 questionnaire (MSQOL-54). Fully automated fluorescence polarization immunoassay was used to measure serum homocysteine, vitamin B12 and folate. Complete blood count blood test was conducted to determine the anemia status. The mean homocysteine level reduced by 2.49± 0.39 µmol/L (p = 0.001), hemoglobin increased from 11.24 ± 1.54 to 13.12 ± 1.05 g/dL (p = 0.001), and mean corpuscular volume decreased from 95.50 ± 6.65 to 89.64 ± 4.24 in the vitamin group (p = 0.001). There was a significant improvement in the mental field of life quality in the placebo group (37.46 ± 19.01 to 50.98 ± 21.64; p = 0.001), whereas both physical and mental fields of quality of life were improved significantly in the vitamin group (40.38 ± 15.07 to 59.21 ± 12.32 and 29.58 ± 15.99 to 51.68 ± 18.22, respectively; p = 0.001). Serum homocysteine level decrease and anemia status improvement with vitamin B12 and folic acid supplementation reveal the potential role of these two vitamins in improving the life quality of MS patients.
