Vitamin B —Can it prevent cognitive decline? A systematic review and meta-analysis

DiscussionWe found no overall evidence that oral vitamin B supplementation prevented cognitive decline. The isolated significant effects that were reported could be attributed to methodological issues. The results of this review do not provide evidence that population groups with certain risk factors would profit more from the intervention than others. Our findings do not apply to forms of administration other than oral supplementation nor do they offer information regarding the treatment of cognitively impaired individuals via the administration of vitamin B.Systematic review registrationPROSPERO CRD42017071692
