Vitamin B12 is vital for the nervous system and is also one of the key elements for the formation of healthy red blood cells. B12 , like folic acid as methyl group donors, promotes the reduction of high homocysteine ​​levels to safe limits. In order for B12 to be used by the body, it first needs to be converted endogenously into methylcobalamin by the effect of the MTRR enzyme. For many people, this endogenous conversion is insufficient due to various reasons such as: genetic abnormalities in the gene related to the MTRR enzyme and in conditions such as pernicious anemia and diabetes. Research has shown that B12 in the form of methylcobalamin is immediately active during its absorption. In addition, B12 as a sublingual tablet has better absorption through the oral mucosa. Suitable for vegans.
