Nutri'B12

"An organic food supplement for your vitamin B12 deficiencies. Additional information Vitamin B12 or cobalamin intervenes in several physiological situations: Synthesis of DNA and RNA. Protein synthesis. Cell division and growth, red blood cells. Contributes to the formation of myelin, the protective envelope of the nerves. Provided by food, vitamin B12 is detached from ingested proteins in the stomach by hydrochloric acid and pepsin. It passes into the duodenum where it binds to intrinsic factor secreted by the fundus of the stomach. Then it is absorbed at the end of the ileum. It binds in the blood to a protein called transcobalamin. This will provide methyl groups in the biochemical operations requiring it (DNA, RNA, homocysteine synthesis, etc.). It is eliminated by the bile but is partly reabsorbed by the intestine, the losses of vitamin B12 are therefore minimized."
