Vitamin B12
In rat and human research studies Vitamin B12 has long been shown to have pain relieving properties.
In numerous rat research studies, B12 has lowered damage to the brain, and lowering seizure activity after toxic injury in rats.
In addition it has shown promise in reducing damage from concussion.
B12 and B6 together were found to reduce nerve and joint pain in rats due to mechanical injury.
