Vitamin B12 (cobalamin) is required for healthy nerve function and the synthesis of red blood cells and DNA. B vitamins are also important for healthy immune function, which is your first line of defense against all diseases
According to recent research, vitamin B12 is a key player in cellular regeneration, as it’s the limiting factor for methylation. DNA in cells that need to be repaired require high levels of methylation, hence high amounts of B12 are required to regenerate damaged tissues
Vitamin B12, applied topically, has also been shown to be helpful in the treatment of radiodermatitis, i.e., skin damaged by radiotherapy used in cancer treatment
A deficiency in B12 increases inflammation and oxidative stress by raising homocysteine. B12 deficiency is also associated with many other physical, neurological and psychological symptoms, including migraines, certain respiratory disorders, depression, memory loss and nonalcoholic steatohepatitis (NASH)
Vitamin B12 is found almost exclusively in animal foods such as beef and beef liver, lamb, snapper, venison, salmon, shrimp, scallops, poultry, eggs and dairy products. If you rarely eat these foods, consider using nutritional yeast, which is high in B12. Sublingual fine mist spray or vitamin B12 injections are also effective
