Studies have reported a significantly higher rate of vitamin B12 deficiency in people with MS than in people without MS, which is suspected to be due to problems with binding and transport of vitamin B12 (meaning that the body does not process vitamin B12 efficiently, which makes it difficult to maintain normal levels without supplementation). One study found low B12 levels in the cerebrospinal fluid of people with MS, although their blood levels were normal.
What Is It For?
People with vitamin B12 deficiency have destruction of both the myelin and the underlying axon. If the deficiency is severe, there can be serious brain damage, causing MS-like symptoms. Even when people have slight B12 deficiency, they may exhibit symptoms like fatigue, depression and memory loss.
How Does It Work?
Vitamin B12 helps maintain the myelin sheath by playing a crucial role in the metabolism of fatty acids essential for the maintenance of myelin.
