Vitamins B12
Always consult your primary physician when starting a nutrition program with Vitamins B12.
Vitamin B12 is an essential vitamin. This means that the body requires vitamin B12 to work properly. Vitamin B12 can be found in foods such as meat, fish, and dairy products. It can also be made in a laboratory. It is often taken in combination with other B vitamins.
Vitamin B12 is most commonly used for vitamin B12 deficiency, a condition in which vitamin B12 levels in the blood are too low, as well as cyanide poisoning and high levels of homocysteine in the blood (hyperhomocysteinemia).
You can get 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. If you're looking for a food fortified with B12, check the product's Nutrition Facts label.
