2 Reasons to Take Vitamin B12
Published: 4/23/2013

Vitamin B12, also known as cyanocobalamin, is a water-soluble vitamin that is vital for the day-to-day metabolic processes of cells. It affects the development and maintenance of red blood cells, nerve cells, and normal myelination (covering) of nerve cells, and it aids in the production of DNA and RNA, and the synthesis of neurotransmitters.

We can obtain vitamin B12 only from animal foods, including dairy, eggs, meat, fish, poultry, and shellfish, so vegetarians and vegans are often at risk for B12 deficiency. Those on chronic acid-suppressing medications, some oral contraceptives and certain blood pressure medications like hydrochlorothiazide are at risk for depletion. In addition, older people may lose the ability to absorb B12 from food and need to take it in supplemental form to maintain adequate levels. Find out if vitamin B12 is recommended for you: take Dr. Weil's Vitamin Advisor.
