Vitamin B12 helps body make DNA and red blood cells. Since body doesn't make vitamin B12, one has to get it from animal-based foods or from supplements. And one must ensure doing this on a regular basis. While B12 is stored in the liver for up to 5 years, one can eventually become deficient if their diet doesn't help maintain the levels. The answer depends on things including your age, your eating habits and medical conditions, and what medications you take.
The average recommended daily amounts of Vitamin B12 vary by age, eating habits and medical conditions, and what medications one takes. One can get their vitamin B12 in animal foods, which have it naturally, or from items that have been fortified with it. Animal sources include dairy products, eggs, fish, meat, and poultry. With age, it becomes harder to absorb Vitamin B12. It also happens if you had weight loss surgery or another operation that removed part of your stomach, and also if you drink heavily.
