However, the current UK recommended nutrient intake for vitamin B12does not adequately consider the vitamin B12deficit for those choosing a plant-based diet, including vegetarianism and in particular veganism, representing a hidden hunger. We provide a cautionary note on the importance of preventing ...
How do vitamins help to keep the body healthy? What is the importance of iron in the human body? Why have primates lost the ability to produce vitamin C? Why is the integumentary system important for the body? Why are vitamins known as a micronutrient? Why are vitamins known as micronutrie...
Their work earned Minot and Murphy the Nobel Prize in Physiology or Medicine in 1934 for their discovery of the importance of Vitamin B12 in the treatment of pernicious anemia. Vitamin B12 is primarily found in animal products such as meat, fish, eggs, and dairy. It is synthesized by ...
Bei den unter dem Sammelbegriff „Vitamin“ fallenden Substanzen ist in erster Linie deren biologische Wirkung von Interesse. Nun ist bei den einzelnen Vitaminen jedoch nicht nur eine Substanz, sondern eine ganze Gruppe von Substanzen Trager dieser Wirkung (siehe dazu G. Brubacher u. Mitarb....
PLP is the active coenzyme form, and has the most importance in human metabolism. PN, PL, and PM are metabolically interconvertible and considered to be biologically active. PN is more stable than PL and PM. The stability of vitamin B6 greatly depends on the type of thermal processing. pH...
It is estimated that between 0.5 and 5.0 µg of B12 is excreted in bile per day. This biliary B12 is readily reabsorbed across the ileal enterocyte and, thus, enterohepatic circulation represents a mechanism by which B12 is conserved by the body. The efficiency of biliary B12 absorption is...
they were broadly upregulated in the pancreas, colon and stomach—but not in the kidney—of mice expressing OSKM (Extended Data Fig.5d). A subset of these genes was basally high in the colon due to their importance in the stem cell compartment. Importantly, B12supplementation generally relieve...

Vitamin B12 supplements typically contain doses that far exceed the recommended daily amount, and high exposures are generally considered safe. Competitive and syntrophic interactions for B12 exist between microbes in the gut. Yet, to what extent excessi
