Vitamin B-12 + Folsäure 500µg / 100µg - 90 tablets

Vitamin B12 with folic acid

This dietary supplement from Fairvital combines vitamin B12 (methylcobalamin) with folic acid (vitamin B9). Both forms are very bioavailable and can be optimally utilized by the body.
One tablet daily provides you with 500 µg vitamin B12 and 100 µg folic acid.

Vitamin B12

Vitamin B12 (scientifically: cobalamin) is one of the 8 water-soluble B vitamins and occupies a special position. On the one hand, it is the only B vitamin that can be stored by the body in significant amounts (2000-4000 µg). This mainly takes place in the liver. On the other hand, the absorption of vitamin B12 depends on a special transport molecule, the so-called intrinsic factor (IF). The formation of this transport molecule takes place in the parietal cells of the stomach.

Intake of vitamin B12

The intrinsic factor binds to the B12 in the small intestine and transports it to special receptors in the intestinal mucosa. If the formation of the intrinsic factor is disturbed by gastric diseases, a vitamin B12 deficiency can occur.
However, vitamin B12 can also be absorbed by passive diffusion . This is usually achieved with high doses of vitamin B12 (from 500-1000 µg).

Vitamin B12 for the nerves

The vitamin plays an important role in a well-functioning nervous system and supports mental well-being. In addition, it is involved in cell division and the formation of red blood cells.
The energy metabolism is also dependent on a sufficient B12 level, so that the macronutrients from the food can be optimally utilized.

B12 in food

Since vitamin B12 is primarily found in animal foods (e.g. eggs, dairy products), supplementation is particularly useful for vegetarians and vegans.
Plant sources include fermented vegetables and legumes in particular, but the amount contained is not sufficient to meet daily needs.
Algae such as Chlorella and spirulina are touted as good sources of B12, but again, amounts are usually very small and some of the B12 form it contains is not biologically active.

Together with cobalamin (B12), folic acid is necessary for a normal homocysteine ​​level in the blood by supporting the breakdown of homocysteine ​​into methionine.
Like vitamin B12, folic acid contributes to a < strong>normal blood formation or formation of red blood cells and to a normal function of the immune system.
Folic acid also supports the mental function and is important for women before and during pregnancy as it contributes to the formation of maternal tissue.

Folic acid in food

Unlike B12, folic acid is primarily found in plant foods. Good sources include spinach, lamb's lettuce, asparagus, peas, chickpeas, soybeans, kale, and Brussels sprouts.
Animal sources include pork liver, cocoa, eggs, and brie.
