Kirkland Signature Expect More Quick Dissolve B-12 5000 mcg, 300 Tablets

Vitamin B12 is a water-soluble vitamin, also commonly called cobalamin, or cyanocobalamin, because of its cobalt atom centered in the molecule. There are also several types of them, collectively called cobalamins. It is interesting that it is not found in food of plant origin, but only in animal origin, and that an internal, intrinsic factor is also required for its absorption from the gastrointestinal tract. Thus, even with adequate intake of vitamin B12, we may be in a state of vitamin deficiency - due to a lack of internal factors.
Of particular interest is the fact that bacteria in our colon, especially the colon, are able to produce this vitamin, but because the colon is no longer absorbing nutrients, unfortunately we cannot utilize this amount.

What do you need?

     Protein metabolism
     Carbohydrate metabolism
     Metabolism of Nitrogenous Materials
     Red blood cell formation, hemoglobin synthesis

How much is needed?
Unfortunately, the absorption loss of vitamin B12 is quite large, since it also requires the intrinsic factor mentioned above. As a result, in the worst case, only 25% of the vitamin intake is utilized. Vitamin B12 supplementation is especially important for vegetarians, as it is not found in our plant nutrients, but the intake of higher amounts of folic acid can obscure the symptoms of anemic anemia.

Where can you find it?
Our best sources of vitamin B12 are liver and meat. It is present in small quantities in milk and dairy products.

Deficiency states
In the absence of vitamin B12, anemic anemia occurs (the production of red blood cells is almost completely stopped), and gastrointestinal and nervous system complaints and symptoms occur.
