Vitamin B-12 + Folic Acid 500μg / 100μg - 90 tablets

Optimised vitamin B-12 with folic acid

What is vitamin B12?

Vitamin B12 (cobalamin) is one of the 8 water-soluble B vitamins and has a special status among them. Firstly, it is the one B vitamin, which the body is able to store in considerable amounts (2000-4000µg) in the liver. Secondly, the resorption of vitamin B 12 is dependent on a special transport molecule, the so-called Intrinsic Factor (IF). The formation of these transport molecules takes place in the parietal cells of the stomach.

Resorption of vitamin B12

The Intrinsic Factor binds the B12 in the small intestine and transports it to special receptors in the intestinal mucosa. That is why an impaired formation process can lead to a vitamin B12 deficiency.
However, it is possible for the body to resorb vitamin B12 via passive diffusion of high vitamin B12 doses (from 500-1000µg).

Function of vitamin B12

Vitamin B12 is needed to form myelin, the protective layer of many peripheral nerve fibres of the spinal cord and the brain. The vitamin also plays a major role in maintaining a well-functioning nervous system and it is involved in cell division and the formation of red blood cells. Furthermore, it supports the mucous membranes.

Vitamin B12 and fertility

The cell division and cell reproduction depends on vitamin B12, which is why it is not surprising that a good B12 supply is important for the sperm count and the male fertility. Women who are well supplied with B12 have a good precondition for a regular ovulation or the development of a fertilised egg, because B12 has a key role in the development of tissue.

B12-rich foods

As vitamin B12 can primarily be found in animal-based products, a B12 supplementation may be reasonable for vegetarians and vegans.

What is folic acid?

Like vitamin B12, folic acid belongs to the 8 water-soluble B vitamins and is also known as vitamin B9. The liver only stores small amounts of folic acid, which are approx. sufficient for 3 to 4 months. Additionally, folic acid is solely stored in its inactive form, which the body cannot utilise. A sufficiently high vitamin B12 level helps to activate the folic acid and make it available for the body.

Function of folic acid

Along with cobalamin, folic acid is needed to form DNA (genetic material). Furthermore, B12 and folic acid contribute to a normal homocysteine level in the blood by supporting the breakdown of homocysteine into methionine.
Like vitamin B12, folic acid contributes to a normal blood formation and a normal function of the immune system.

Folic acid-rich foods

Noteworthy amounts of folic acid occur in animal-based foods as well as in plant-based foods, including legumes, liver, green leafy vegetables, egg yolks, tomatoes and oranges.
