With reports of Simon Cowell, Madonna, Justin Timberlake, Katy Perry Justin Bieber, and Victoria Beckham having regular supplements of vitamin B12 to improve their health and energy levels, vitamin B12 is constantly in the popular press these days.

European researchers have also shown that giving B12 to people deficient in the vitamin helped protect many of the areas of the brain damaged by Alzheimer’s disease. In a two-year study at the University of Oxford of 270 people older than 70 with mild cognitive impairment and low B12 levels, Dr. Helga Refsum, a professor of nutrition at the University of Oslo, found reduced cerebral atrophy in those treated with high doses of the vitamin.
“A B12 vitamin deficiency as a cause of cognitive issues is more common than we think, especially among the elderly who live alone and don’t eat properly,” Dr. Rajarethinam said.
A nutritional supplement (L-methylfolate, methylcobalamin, and N-acetyl-cysteine) for hyperhomocysteinemia (HHcy) in patients with Alzheimer’s disease (AD) or cognitive impairment due to cerebrovascular disease (CVD) slowed regional brain atrophy. The nutritional supplement was associated with significantly slowed hippocampal and cortical atrophy rates in patients with Alzheimer’s disease, and related disorders, with hyperhomocysteinemia, and forebrain parenchymal atrophy rates in CVD patients with hyperhomocysteinemia.
