We hear a lot about the benefit, or lack of benefit we get from taking vitamins from numerous sources including, television, radio and the internet. Despite the conclusions you reach regarding whether it is beneficial to take vitamin supplements yourself, it’s a fact that the proper levels of certain vitamins in your system are absolutely vital. Those lacking in B vitamins may experience symptoms such as depression, psychosis, or pellagra, a bona fide disease that is nearly identical to schizophrenia. Vitamin C deficiency can lead to mental fog, depression, and in some cases, even psychosis.
