Vitamin B12 is a water-soluble vitamin. Water-soluble vitamins dissolve in water. After the body uses these vitamins, leftover amounts leave the body through the urine.
The body can store vitamin B12 for years in the liver.
Vitamin B12, like the other B vitamins, is important for protein metabolism. It helps in the formation of red blood cells and in the maintenance of the central nervous system.
Vitamin B12 deficiency and depletion are much more common than previously thought, especially in the over-60 population. In fact, it's believed that almost one in four people over 60 have deficient levels of this vital vitamin.
Equally disturbing are emerging signs that other age groups harbor suboptimal blood levels of B12 as well.
Why is vitamin B12 deficiency such a big deal?
Your body depends on vitamin B12 for a host of functions, including…
When your blood levels of vitamin B12 are low, one or more of these functions may be disrupted.*
Without adequate blood levels of B12, you can experience symptoms related to low energy, mental fatigue, mood changes, sleep difficulties, and even occasional indigestion.*
Your body relies on the efficient conversion of carbohydrates to glucose - your body's source of fuel - just like your car needs to be able to use gas to run smoothly. Vitamin B12 plays a major role in that conversion in your body.* Likewise, B12 enables your body to convert fatty acids into energy as well.*
Contrary to what you might have heard, there's really no solid evidence that supplemental vitamin B12 helps you lose weight.
Overall, vitamin B12 is a nutrient your body cannot do without for efficient, healthy metabolism of fats and carbohydrates.*
The older you get the more likely you are to have a vitamin B12 deficiency. The two ways that you become deficient in vitamin B12 are from not getting enough in your diet and from losing the ability to absorb it.
I recently visited India which is primarily a vegetarian based culture and current studies there show about 80% of the adults are deficient in vitamin B12. However, vegans are not the only ones who can become vitamin B12 deficient.
The older you get the more your digestive system breaks down, especially if you have been following the standard American diet. Specifically the lining of your stomach gradually loses its ability to produce hydrochloric acid which releases vitamin B12 from your food. The use of antacids or anti-ulcer drugs will also lower your stomach acid secretion and decrease your ability to absorb vitamin B12. Infection with Helicobactor pylori, a common contributor to stomach ulcers, can also result in vitamin B12 deficiency.
However the main cause of vitamin B12 deficiency is a term researchers call food-cobalamin malabsorption syndrome. Cobalamin is the scientific term for vitamin B12. This typically results when your stomach lining loses its ability to produce intrinsic factor which is a protein that binds to vitamin B12 and allows your body to absorb it at the end of your small intestine.
