Especially animal products such as meat, fish and dairy products contain a lot of vitamin B12. The top performers in the B12 comparison from the above categories are as follows:

Vitamin B12 content per 100 grams:

  • Liver: approx. 30 - 60 mg

8. disturbed vitamin B12 intake in the absence of intrinsic factor

Vitamin B12 can be absorbed by the body in two ways. On the one hand, the vitamin can be passively made available to the intestine if a high vitamin B12 level is present. On the other hand, the body itself can Take 1.5 mg vitamin B12. However, some kind of catalyst is necessary for this: The intrinsic factor ensures that the vitamin B12 can be safely transported through the acidic stomach milieu to the place where it is absorbed in the intestines. If the intrinsic factor is missing, no active absorption of the vitamin B12, and it can only be absorbed by means of passive diffusion itself, which continues. If the intrinsic factor is missing in the context of a vitamin B12 uptake disorder, it is advisable to supplement the normal diet with Take vitamin B12 in the form of vitamin B12 tablets or capsules to provide B12 in high quantities via passive diffusion.

9. the correct vitamin B12 form: Cyanocobalamin or methylcobalamin?

Cyanocoblamine is found in most vitamin B12 supplements and dietary supplements. It is cheap for the manufacturer and easy to process. However, the problem is that many people cannot tolerate this substance and Rashes or other allergic reactions may occur due to the intake of cyanocobalamin. For this reason, methylcobalamin is the better choice. It is often extracted from lichens, a plant species. Methylcobalamin is clearly more expensive to produce, but can be more easily absorbed by the body and is much better tolerated by people who are sensitive to food supplements.

10. vitamin B12 capsules as an alternative to tablets

Many people use cheap vitamin B12 tablets from the drugstore or pharmacy to meet their vitamin B12 needs. However, in addition to the cheap cyanocobalamin already mentioned, vitamin B12 tablets are also used in In most cases a variety of artificial additives are used to make the tablets easier to produce. These range from fillers such as silicon dioxide to magnesium stearate or nanosubstances such as microcrystalline cellulose, which can overcome the intestinal wall and remain in the body indefinitely. For this reason, choosing vegetable vitamin B12 capsules is often the better choice. These can be produced without additives and are just as effective as vitamin B12 tablets. If you want to buy vitamin B12 capsules, you should make sure that they contain pure methylcobalamin, are free of artificial additives and are produced in Germany.

11. test vitamin B12 levels

In order to determine a vitamin B12 deficiency or undersupply, the best way is an MMA test at the doctor's. This test checks the level of methylmalonic acid. If the MMA level is significantly elevated, this indicates a deficiency of vitamin B12. The test is simple and very meaningful, as it only measures the vitamin B12 value that can be actively used by the body. We recommend having the test performed at regular intervals if there is a suspicion of a vitamin B12 deficiency exists. Since the B12 depot only decomposes slowly, even in the case of a deficiency, several tests have a higher significance than a single test and allow us to conclude with certainty whether a B12 deficiency exists or not.

12. conclusion
