Vitamins b6 and b12 support your bodyâ??s metabolism and produces neurotransmitters and red blood cells. Vitamins b6 and b12 are seldom a deficiency, as they are found in a multitude of foods.
Vitamin B12 is found in foods of animal origin (meat, fish, poultry, eggs and dairy products) so most people get enough from the foods they eat; however, some individuals can't absorb it. Normally, when you eat food, the hydrochloric acid and digestive enzymes in your stomach release vitamin B12. Then the free vitamin B12 combines with a substance called intrinsic factor, which helps your small intestine absorb it.
I really believe that the B12 thing is exaggerated. How many vegans with pernicious anemia are there? You can get B12 from supplements and foods such as nutritional yeast, seaweed, and miso.
The SR B12 blood test measures the levels of vitamin B12 in your blood. It is used to diagnose vitamin B12 deficiency, which can lead to symptoms like fatigue, weakness, and nerve problems. Low levels of vitamin B12 can be caused by conditions like pernicious anemia, malabsorption issues, or a diet lacking in B12-rich foods.
It is easy for vegans to get enough enough vitamin B12. There are lots of vegan B12 supplements and fortified foods. Also, nutritional yeast is a delicious ingredient that is high in B12.
Plant-based sources of B12 include fortified foods like plant-based milks, cereals, and nutritional yeast. Some algae and seaweed products may also contain B12, but it's important to check labels for accuracy.
The B vitamins are water soluble, which means that what is not used immediately by the body is excreted in the urine vitamin B12 can be stored in the liver for a long time. Vitamin B12 is available in certain food sources, such as meat, dairy and eggs. If you are a vegetarian, or don't consume these foods in high amounts, you should take a vitamin B12 supplement to prevent a deficiency.
The foods that are highest in B12 are shellfish; liver, especially beef liver; fish such as herring, smoked salmon, and tuna; soy products like tofu, and the type of cereals that are fortified with vitamin B12 such as All Bran. You should not take estrogen pills without checking with your doctor. Any excess vitamin B12 leaves the body or is stored by the liver for when you need it.
Pernicious anemia can be treated with injections of vitamin B12, and possibly with B12 vitamin pills. Pernicious anemia is a vitamin B12 deficiency disease, B12 is required to make healthy red blood cells and can normally be obtained from animal based foods, including, meats, fish, dairy products and eggs (but not plant foods), however, when people choose not to eat animal products, vegans for instance, they may suffer a B12 deficiency. Also, inadequate absorption can occur when there is an insufficient amount of a specific protein referred to as "intrinsic factor" in the body that is normally released by stomach cells.
