13. Helps Prevent AIDS
AIDS (Auto Immune Deficiency Syndrome) is a disease that destroys the body’s immune system, leaving it incapable of defending the body from viral and bacterial attacks. It has been discovered that AIDS patients are generally deficient in Vitamin B12. In laboratory tests Vitamin B12 has been found to reduce the replication of the HIV virus, the virus that attacks the immune system causing AIDS. It is thought that increasing the levels of Vitamin B12 in the body will have the same effect, leading to an increased ability to resist the virus.
