What is the best source of vitamin B12?

Answer 1

Good food sources of vitamin B6 include brewer's yeast, potatoes, pistachios, sunflower seeds, spinach, bananas, lentils, avocados, sweet potatoes, winter squash, yams, green peas, sesame seeds, bell peppers, turnip greens, summer squash, shiitake mushrooms, collard greens, chickpeas, garlic, leeks, cauliflower, Brussels sprouts, onions, hazelnuts, kale, pineapples, and carrots.

Answer 2

Neither plants nor animals synthesize vitamin B12: only bacteria make the biologically active form. Animal tissues can store the B12 made by the bacteria, which can then be passed along to carnivores when they eat animal tissue. Ruminants (cows, goats, sheep, giraffes, llamas, buffalo, and deer) have bacteria in their rumens (stomachs) that synthesize vitamin B12, which is then passed down and absorbed by their small intestines. Large carnivores get their B12 from eating these grazers.

Your digestive tract also contains B12-synthesizing bacteria, which is one reason that vitamin B12 deficiency disease is rare in humans, even among vegans. Most of the bacteria is in your colon, and B12 is absorbed "upstream" in the ileum, so you don't absorb the B12 that's made in your colon unless it somehow gets back into your upper digestive tract. Feces contain large amounts of active B12. Our ancestors lived in close contact with each other and their farm animals, and they got their B12 by eating unsanitized food. We now live in over-sanitized conditions, and the need for B12 supplementation for vegans is the result of our obsession with cleanliness.

If you were raised on an omnivorous diet, you probably have about 2 to 5 milligrams of B12 stored, mostly in your liver. That's at least a three-year reserve. Your body can conserve this supply by reabsorbing B12 from your bile, making your reserves last an average of 20 to 30 years after becoming a strict vegan if you consume no B12. In reality, you do get small amounts of B12 from your intestinal bacteria, unwashed vegetables, and the environment.

When you consume vitamin B12, hydrochloric acid in your stomach separates it from any protein to which it may be attached. Then, vitamin B12 combines with a protein made by your stomach called intrinsic factor and is absorbed by your body. Some people have pernicious anemia, a condition where they cannot make intrinsic factor. As a result, they have trouble absorbing vitamin B12 from food and supplements.

Answer 3

The B Complex includes several important vitamins which play critical roles in maintaining good health. Vitamin B12, also known as cobalamin, is responsible for several functions including the development of red blood cells, maintaining the nervous system, and boosting metabolism. Due to its role in red blood cell maintenance, a deficiency in Vitamin B12 can lead to some serious symptoms such as poor blood clotting and irregular heart beats. Animal products are the best sources of Vitamin B12 because this essential nutrient is not synthesized or stored in plants. Calf's liver, sardines, eggs, and dairy are some of the well known food sources of Vitamin B12.

Answer 4

Chicken is probably considered the best source for B12.

Answer 5

food that are naturally found in animals. fortified breads and cereal's or supplements. Beef, tuna, and chicken.

Answer 6

Calf's liver is the number one source of Vitamin B12, but sardines is a good source too.
