WHY IS VITAMIN B12 IMPORTANT?

The name of vitamin B12, cobalamin, comes from its cobalt content. Vitamin B12 is the only water-soluble vitamin that is stored to our bodies and which has long half life – around one year in the liver. In case of insufficient vitamin B12 intake, it takes usually years before it is possible to diagnose vitamin B12 deficiency.

We need vitamin B12 for normal amino acid metabolism, formation of red blood cells and normal development of nervous system. We get vitamin B12 active forms only from animal-based and vitamin B12 enriched plant-based foods.

How to use the product

Vitamin B12-drops can be dosed in two different ways: drop on the tongue and swallow for absorption through gut or drop under the tongue for absorption through mucosa (in case of malabsorption through gut).

B12 content

B12 drops for infants and children 1 drop consists of 100 mcg of vitamin B12 – the smallest amount of B12 (methylcobalamin) in liquid form in Estonia. It is easier for medical staff to make dose guidelines and also dosing mistakes (under- and overdosing) are smaller. B12 drops for the whole family 1 drop consists of 500 mcg.

Absorption of B12

Vitamin B12 is absorbed around 2 mcg by active mechanism and in addition, 1% by passive mechanism through the whole small intestine area. In case of supplements, it is the passive mechanism that plays the key role. The active absorption of vitamin B12 differs greatly from other water-soluble vitamins: first B12 binds with intrinsic factor, IF, glycoprotein in the stomach and then gets absorbed in the final part of the small intestine, ileum.
