Cyanocobalamin

Cyanocobalamin biologically active substance called cobalamin.This important vitamin for the human body is only in animal products.Today we debunk myths about the B12, describe what it is and what it eats.

This is the most complex structure of the vitamin. Its uniqueness does not end there - it is the only vitamin that is produced exclusively by bacteria that live in animals, so in plant foods is not B12.The highest concentration was found in beef and pork liver.This was first identified by William Murphy, who has done research on artificial anemic dogs.Individuals who ate large amounts of liver, quickly recovered from anemia.

On cobalamin absorption is influenced by many factors:

  • The first step is the production of so-called stomachKastla factor, which is necessary for the full assimilation of the vitamin;
  • Excessive intake of vitamin C, it prevents the absorption of B12;
  • Lack of calcium.Its ions are necessary for the successful assimilation of B12.But calcium deficiency is the same problem as cobalamin def
    iciency;
  • Violations of the pancreas.Her secrets are also involved in the absorption of B12;
  • presence of worms and worms that produce toxins;
  • serious impediment is the presence of pathogenic bacteria in the lower part of the small intestine, where it is sucked B12.
