What does Vitamin B12 do?

What does Vitamin B12 do?

What does Vitamin B12 do? Well first you got to know what it is. Vitamin B-12 is a water-soluble nutrient that must be consumed regularly due to the bodies inability to produce it. 

It is a vital micronutrient used for many important bodily functions such as production of red blood cells and DNA, good nerve tissue health, and optimal brain function.

Unfortunately, the National Institute of Health estimates that up to 15% of Americans are vitamin B-12 deficient (1), with elderly and vegans being most susceptible.

The benefits your body gains from optimal B-12 intake are impressive. Many reviews claim that B-12 supplements help them improve mood and symptoms of depression.

Although not fully understood, vitamin B-12 is an important component in making and processing serotonin, a vital chemical for mood regulation.

One study done showed that receiving vitamin B12 supplements along with anti depressant were more likely to have improved depressive symptoms compared to anti depressants alone (2).

A different study found that being deficient in B12 was with twice the risk of severe depression (3). There are various other benefits vitamin B12 offers as well.

Dosage and Deficiency

The daily intake of vitamin B-12 for most adults is 2.4 micrograms (mcg). Consuming less than this amount for an extended period of time can lead to deficiency. Signs of deficiency are vast.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
