Vitamin B12 supplements are not known to cause false positives for methamphetamine in drug tests. However, certain medical conditions or other substances can sometimes lead to false positives for various drugs. It's always best to consult with a healthcare professional if there are concerns about drug testing results.
None. The human body can not produce B12. It has to get it from food.
Of course it can. Remember absorbed vitamine B12 from the gut forms B12+transcobalamin II complex in the blood ? And your liver has to produce special transporters for this complex before your bone marrow can use the B12+transcobalamin II complex in making red blood cells. So liver disease reduces the transporter and subsequently impairs the blooding making machinery in bone marrow (as you must already know that B12 is needed to produce erythrocytes)
No, hydrochloric acid (HCl) is not necessary to produce the intrinsic factor for cobalamin. HCl is needed along with gastric enzymes to free Cobalamin (B12) from its polypeptide linkages in food. The intrinsic factor involved with the digestion and absorption of Cobalamin (B12) is a glycoprotein.
Vitamin B12 is produced by certain bacteria found in the gut of animals, which is why it is primarily found in animal products such as meat, fish, dairy, and eggs. Plants do not produce vitamin B12 naturally.
Neither plants nor animals are independently capable of constructing vitamin B12 (Only bacteria have the enzymes required for its synthesis). B12 is replenished in the body from dietary sources.
Parietal cells in the stomach are essential for vitamin B12 absorption because they produce intrinsic factor, a glycoprotein crucial for the absorption of vitamin B12 in the small intestine. When food enters the stomach, vitamin B12 binds to intrinsic factor, forming a complex that protects it from digestion. This complex is then absorbed in the ileum, the final part of the small intestine. Without intrinsic factor, vitamin B12 cannot be effectively absorbed, leading to potential deficiencies.
B12 is a self protien which can improve the intrinsic factor by re building mucose membrane and this helps in better digestion the salvary gland aare improved due to b12 .
No, vitamin B12 is not a barbiturate
B12 is a vitamin
pernicious anemia is a vitamin B12 deficiency. Vitamin B12 requires Intrinsic Factor to be reabsorbed by the ileum. Intrinsic Factor is produced by parietal cells in stomach. If there is some damage or manipulation of parietal cells, which also produce HCl, there will be less of both intrinsic factor causing B12 deficiency and HCl causing achlorhydria.
