How does it work?
Vitamin B12 is one of eight water-soluble B vitamins that your body needs on a regular basis. All B vitamins help the body convert carbohydrates into sugar, which is "burned" to produce energy.In addition to playing a role in the breakdown of fats and carbohydrates for energy.
Who is it used for?
Vitamin B12 is an essential vitamin that your body needs to convert carbohydrate into energy. Symptoms of a vitamin B12 deficiency may include fatigue, shortness of breath, diarrhea, nervousness, numbness or tingling sensation in the fingers and toes.
How does it work?
Vitamin B12, also called cobalamin, is an especially important vitamin for maintaining healthy nerve cells and it aids in the production of DNA and RNA, the body's genetic material. Vitamin B12 also works closely together with other B vitamins to regulate the formation of red blood cells and to help iron function better in the body. The synthesis of S-adenosylmethionine (SAMe), a compound involved in immune function and mood, depends on the participation of folate and vitamin B12.

B complex vitamins also play an important role in maintaining muscle tone along the digestive tract and promoting the health of the nervous system, skin, hair, eyes, mouth, and liver. The B vitamins also help to lower homocysteine levels in your body. Homocysteine is an amino acid (an amino acid is a "building block" for protein) found in your blood. Homocysteine levels can increase when your body doesn't completely transform the amino acid methionine (which comes from food) into the various derivatives needed for the formation of protein in the tissues of your body. For most people, the rise in homocysteine is caused by a deficiency in the B vitamins [1, 2, 3].

Vegetarians who follow a strict vegan or macrobiotic diet or at a high risk of a deficiency, as vitamin B12 is found mainly in fish, dairy products, organ meats (particularly liver and kidney), eggs, beef, and pork.
How do I use it?
Vitamin B12 is considered safe and non-toxic, and can be taken as part of a multi-vitamin or a B-complex supplement.
What results can I expect?
If you're deficient in vitamin B12, using a supplement will help to raise your energy levels and prevent symptoms of a deficiency, such as fatigue, shortness of breath, diarrhea, nervousness, numbness or tingling sensation in the fingers and toes.
What can it be combined with?
The vitamin can be taken as part of a B-complex or high-quality multi-vitamin supplement.
