List of B Vitamins & Benefits for Physical and Mental Health

Normal metabolism, growth and development require B vitamins, each playing a specific role and working together to perform biological functions. Deficiencies of B vitamins can lead to anemia, fatigue, depression, confusion, poor immune function, abnormal heart rate and poor muscle control. There is limited scientific evidence supporting the use of vitamin B supplements to decrease the risk of chronic disease; however, some studies show a link between B vitamins and a decreased incidence of heart disease and certain types of cancers.
