Vitamin B12 is part of the water soluble B complex that is mostly consumed in animal protein. Unlike all other B vitamins, vitamin B12 can be stored by the body, however it does not appear to reach toxic levels. Vitamin B12 has strong influences on the blood and works synergistically with folic acid in regulating the formation of healthy red blood cells. It is also responsible for many other functions including metabolism of carbohydrates and fats, synthesis of protein and many others.
There can be several reasons why one could be deficient such as not having it in the diet, malabsorption of B12 through the digestive system, and sustained loss of blood. Luckily B12 deficiencies are easy to detect with routine blood test.
B12 in most supplements is Cyanobalamin, however Clinicians has formulated a sublingual form of B12 that is methylcobalamin. Methylcobalamin is the active form in the body and is absorbed and utilised more efficiently. It is easily absorbed under the tongue for convenience and enhanced uptake.
