What is Vitamin B12?

Termed Vitamin B12, vitamin B12 vitamin B-12 or cobalamin is an essential part of nutrition that acts on the brain, nervous system and helps with the formation of blood. It is one of the eight B vitamins within this group and helps with metabolism (the process which the body converts, produces and maintains health and energy).

What Are The Effects Of Vitamin B12 Deficiency?

Vitamin B12 works on the nervous system and, when people suffer with a lack of this, can cause irrepairable damage. Even when vitamin B-12 levels are just under normal, it can cause symptoms of fatigue, depression and poor memory. However, if these symptoms present themselves, it may be difficult to diagnose. In extreme cases, a vitamin B-12 deficiency (Resource Box 1) can lead to death if untreated.

A lack of cobalamin may cause mania and psychosis. Furthermore, a vitamin B12 deficiency may be the cause of a condition known as pernicious anemia (Resource Box 2). It is, for example, important for people who have a gastric bypass to get regular injections of b12 because they no longer have the same level of production of gastric acid which plays a key role in the absorption of the vitamin.

The good news is that with supplementation, the condition - providing the disease has not gone too far - can improve people's well being and zest for life. It has been known to help older people (Resource Box 3) with diseases associated with the brain, particularly Alzheimer's, and those who take Metformin in type 2 diabetes (Resource Box 4).

Important Note:

  • It is always advisable to check with your Doctor before taking any medications or supplements.

Recommended Vitamin B12 Supplement

Wonder Laboratories advanced sublingual B12 contains 1000 micrograms of B12, vitamin B6 (5mg), Folic Acid (400 mcg) & Biotin (25mcg).

This can be taken every two or three days and is absorbed under the tongue (sublingual). This is good news because, unlike most nutrients, absorption of vitamin B12 actually begins in the mouth.

Furthermore, the great thing about this product is the vitamin B-12 is combined with other nutrients for greater absorption to help you feel good.

By dissolving the tablet under the tongue, it goes directly to the blood stream. If you have problems with absorbing cobalamin, this product just might be what you are looking for to supplement you.

I liked this product so much that I have had to import it to the UK - they don't sell it here - but don't take my word for it, see what others say by clicking on the link and checking out the reviews!

What Are The Benefits Of Vitamin B12?

So, we have discussed that the lack of cobalamin can lead to forms of anemia, but what are the benefits of vitamin B12 to the body?

In this easy guide, we will sum it up in the following:

  • B-12 helps to break down fat and carbohydrate. It can, therefore, help to maintain a healthy weight because it acts on the metabolism.
  • It is essential to life, bringing forth energy and staying power.
  • It helps the liver and digestive system to function effectively, keeping the body in balance.
  • Improve memory, particulary those with Alzeimers.
  • Helps to boost immunity, thereby, warding off illnesses.
  • Promotes well being.

It is important to understand that the B12 vitamin is essential for life. This point is the greatest of the benefits of B12. As hinted previously, however, and as part of the complex B group, B12 works most effectively with the other B vitamins.

      That is wonderful moneycop, although animal protein is the best source, if you are vegetarian, you can at least get it from nuts, pulses and some vegetables. Thank you for stopping by.

      @Pamela - Looking after the functions of your body brings well being into your life. Nature has a way of providing everything we need should we choose to partake in its natural abundance - without processing it. However, the top up with supplements can help improve things further. Wishing you continued great health and well being :)

      Thank you KoffeeKlatch. Glad that you are having a degree of success. I wonder if the increase will improve - it seems by the bbc report that, over a period, the lady on the video recovered her walking ability.

      Just as B12 stores can depleat over a year, it might be that the stores recover over a period too.

      Just a thought :)

      I like the way you put this information together. I recently started taking vitamin B12 every day - as per doctor instructions. I have found a slight increase in energy and hopefully I will find it has greatly increased my metabolism. Up and useful.
