what blocks b12 absorption?
B12, also known as cobalamin, is an essential nutrient that plays a crucial role in the proper functioning of our bodies. However, the absorption of B12 can be hindered by several factors. One common cause is the lack of intrinsic factor, which is a protein produced by the stomach that helps the absorption of B12 in the small intestine. Certain medications, such as proton pump inhibitors and metformin, can interfere with the production or activity of intrinsic factor, leading to B12 deficiency. Additionally, conditions that affect the digestive system, such as Crohn’s disease, celiac disease, and bacterial overgrowth, can also impair B12 absorption. Furthermore, aging can result in a decrease in the production of intrinsic factor, making older adults more susceptible to B12 deficiency.
what form of b12 is best absorbed?
B12, also known as cobalamin, is an essential vitamin that plays a crucial role in various bodily functions, including the production of red blood cells, DNA synthesis, and nerve function. When it comes to absorption, the form of B12 that is best absorbed by the body is methylcobalamin. This form is directly absorbed into the bloodstream through the lining of the small intestine. It is also the most active form of B12, meaning it can be used by the body immediately without any further conversion.
If you are looking for a B12 supplement, it is important to choose one that contains methylcobalamin. This will ensure that you are getting the most absorbable and active form of the vitamin. Methylcobalamin is also found naturally in some foods, such as meat, fish, poultry, eggs, and dairy products. If you are on a vegan or vegetarian diet, you may need to take a B12 supplement to ensure that you are getting enough of this essential vitamin.
what causes vitamin b12 deficiency?
Vitamin B12 deficiency can occur due to several factors, including:
– Pernicious anemia: An autoimmune condition in which the body attacks and destroys the cells in the stomach that produce intrinsic factor, a protein necessary for B12 absorption.
– Inadequate intake: A diet lacking in B12-rich foods, such as meat, poultry, fish, eggs, and fortified cereals, can lead to deficiency.
– Malabsorption: Conditions that affect the absorption of B12, such as celiac disease, Crohn’s disease, bacterial overgrowth in the small intestine, and certain medications, can cause deficiency.
– Gastric surgery: Surgeries that remove or bypass part of the stomach, such as a gastrectomy or Roux-en-Y gastric bypass, can interfere with B12 absorption.
– Medications: Some medications, such as metformin for diabetes and proton pump inhibitors for acid reflux, can interfere with B12 absorption.
– Age: As people age, their ability to absorb B12 from food decreases, making them more susceptible to deficiency.
– Increased demand: Certain conditions, such as pregnancy, breastfeeding, and rapid growth in children, can increase the body’s demand for B12, potentially leading to deficiency if intake is not adequate.
how long does b12 deficiency take to correct?
Vitamin B12 deficiency can take a long time to correct. It depends on the severity of the deficiency and how it is treated. If the deficiency is mild, it may take a few months to correct. If the deficiency is severe, it may take a year or more to correct. Treatment for vitamin B12 deficiency typically involves taking supplements or injections of vitamin B12. The amount of vitamin B12 that is needed to correct the deficiency will vary depending on the individual. Once the deficiency is corrected, it is important to continue taking vitamin B12 supplements or injections to prevent the deficiency from recurring.
how much vitamin b12 should a person over 65 take?
