Impact of supplementation with "multivitamin-mineral" specially formulated to improve fatigue and inflammatory state in patients with multiple sclerosis: A triple-blind, randomized, placebo-controlled trial

Background: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system (CNS) with the most common complaint of fatigue. A high number of patients with MS are interested in taking dietary supplements as a complementary therapy. We propose a specially formulated supplement for patients with MS and aim to evaluate its effects on fatigue. Methods: This study was a triple-blind, randomized, placebo-controlled trial using a stratified randomization method according to sex. 46 eligible patients participated in the study, 23 in the placebo group and 23 in the intervention group. The intervention group received two capsules of multivitamin-mineral (MVM) daily for 3 months. Measurements of fatigue and cytokines were performed in all patients at the baseline and after the 3-month intervention Results: Finally, information of 41 participants was used for data analysis. However, fatigue was decreased after supplementation than before, in the intervention group (P = 0.005). There was no significant difference (P = 0.090) between the change of fatigue score in the MVM group (-3.00 ± 4.42) and the control group (-0.40 ± 5.14). Among cytokines, Interleukin 4 (IL-4) significantly increased in the intervention group compared to the placebo (P = 0.030). Conclusion: Our study showed that the present MVM probably could improve the inflammatory state and fatigue in patients with MS.
