To learn more about what vitamin B12 does for the body, pop a bit of knowledge with Groupon's introduction.

Vitamin B12 is considered an essential vitamin for a reason: it keeps nerve and blood cells healthy, supports the creation of DNA and RNA, and works with other B vitamins to support one's mood. It's also been used to treat maladies from heart disease to breast cancer to fatigue.

Most people already consume appropriate amounts of vitamin B12, although deficiency can occur in the elderly and those with dietary restrictions.

Vitamin B12 benefits your mood, energy level, memory, heart, skin, hair, digestion and more. Vitamin B12 is also an essential vitamin for addressing adrenal fatigue, multiple metabolic functions - including enzyme production, DNA synthesis and hormonal balance - and maintaining healthy nervous and cardiovascular systems.

Because of its wide-reaching roles within the body, a vitamin B12 deficiency can show up in many different negative symptoms, many of which are very noticeable, such as potential chronic fatigue, mood disorders like depression, and chronic stress or feeling run down.
