                                Meningitis is a dangerous inflammation of the membranes covering the brain and spinal cord, and while it is not directly caused by a vitamin deficiency, nutritional deficiencies can weaken the immune system, increasing vulnerability to the infections that do cause it. The relationship between vitamins and meningitis is often misunderstood, but research shows that deficiencies in certain vitamins, such as B12 and A, can increase an individual's susceptibility to infections that might lead to meningitis.
