Vitamin B12 for Energy

Vitamin B12, also known as cyanocobalamin or cobalamin, is a key factor in the body's function of releasing energy from proteins, carbohydrates, and fats. B12 also activates the metabolically active form of folate, helps to maintain the body's nervous system (blood cell formation and bone metabolism), and prevents anemia.

Meat, fish, eggs, poultry, milk, and milk products, are all good sources of vitamin B12. Fortified foods, like breakfast cereals, can also contain B12 vitamins.

The recommended daily intake of vitamin B12 for males and females 19 years of age and older is 2.4ug. Supplements are beneficial for those over 50 years of age as faulty absorption has been found to occur in 10-30% of people in this age group. Consuming foods fortified with vitamin B12 is also suggested.
