Vitamin B12 is a water-soluble vitamin that is mainly stored in the liver. It is an important vitamin for maintaining healthy nerve cells. It is of special interest to vegetarians and vegans since it is not found in any meaningful amounts in plant foods. Deficiency of Vitamin B-12 can be a serious health issue and should not be taken lightly. Many people as they age may be unable to absorb the Vitamin B12 benefits found in foods. This is because stomach's production of acid tends to decrease as we get older. It is this stomach acid that is necessary to break Vitamin B12 away from the proteins in food. This process must happen first before Vitamin B12 can bind with what is called intrinsic factor in our small intestines before then being absorbed. Vitamin B12 is highly beneficial in various forms but DEVA Sublingual B-12 contains only one form: Methylcobalamin. Methylcobalamin, the coenzyme form of vitamin B12 is a body-friendly version and it can be used in its normal form. Our product comes as a sublingual tablet that dissolves under the tongue.
