A meta-analysis of six research articles explored the relationship between blood levels of vitamin B12 and homocysteine and multiple sclerosis in 639 multiple sclerosis patients and 430 healthy individuals. The analysis confirmed that multiple sclerosis patients had a low blood level of vitamin B12 and a high blood level of homocysteine compared to healthy controls. In addition, vitamin B12 deficiency was found to increase the risk of multiple sclerosis.
