Does milk interfere with vitamin absorption?
Yes
How does disease affect vitamin absorption?
Vitamin treatment is important during specific diseases where the body's normal processing of a vitamin is impaired.
Which nutrient requires intrinsic factor for absorption?
Vitamin B12 requires intrinsic factor for absorption in the small intestine. Intrinsic factor is produced by the stomach and binds to vitamin B12 to facilitate its absorption in the ileum. Without intrinsic factor, vitamin B12 absorption is impaired, leading to deficiency.
What will the Lack of intrinsic factor result in?
A lack of intrinsic factor will result in impaired absorption of vitamin B12 in the intestines, leading to a condition called pernicious anemia. This can cause symptoms such as fatigue, weakness, and neurological issues if left untreated. Treatment often involves regular B12 injections to bypass the absorption issue.
What vitamin destroy vitamin K in the intestines?
Vitamin K is not destroyed by any specific vitamin in the intestines. However, certain medications or substances can interfere with the absorption or utilization of vitamin K in the body. These include: Vitamin K antagonists: Medications such as warfarin (Coumadin) and other anticoagulants work by inhibiting the function of vitamin K in the clotting process. They interfere with the activity of vitamin K-dependent clotting factors, which can reduce the blood's ability to clot effectively. However, they do not destroy vitamin K itself. Orlistat: Orlistat is a medication used for weight loss that works by blocking the absorption of dietary fat. Since vitamin K is a fat-soluble vitamin, the use of orlistat may potentially reduce the absorption of vitamin K from food. However, it does not directly destroy vitamin K. Broad-spectrum antibiotics: Some studies suggest that long-term use of broad-spectrum antibiotics may disrupt the balance of gut bacteria, potentially affecting the synthesis of vitamin K by the intestinal bacteria. This could reduce the availability of vitamin K in the body, but it does not destroy vitamin K. It's important to note that these substances do not destroy vitamin K itself but rather interfere with its utilization or absorption in the body. Vitamin K is essential for blood clotting, bone health, and other physiological functions, so it is important to ensure an adequate intake of vitamin K-rich foods or supplements when necessary. If you have concerns about your vitamin K levels or interactions with certain medications, it is best to consult with a healthcare professional or a registered dietitian who can provide personalized advice based on your specific situation and medical history.
What gland increases blood calcium level stimulates calcium re-absorption and activates vitamin D?
The parathyroid gland is responsible for increasing blood calcium levels by stimulating calcium re-absorption in the kidneys and activating vitamin D, which helps in calcium absorption in the intestines.
The absorption of which vitamin would be impaired by the removal of the stomach?
Vitamin B12 is released from proteins by concentrated levels of HCL acid in the stomach. Therefore, without the stomach there would be no HCL acid to release the B12
What vitamin and mineral supplements should not be taken together?
Some interactions between vitamins may lead to its poor absorption. For instance, iron supplements do not go together well with zinc and may also interfere with absorption of vitamin E. Calcium impedes the absorption of iron that's why they should not be taken together.
Does vitamin d act as a hormone?
Yes, vitamin D functions as a hormone in the body. It helps regulate calcium and phosphorus absorption in the intestines, promotes bone health, and plays a role in immune function.
What are the causes of primary biliary cirrhosis?
A lack of vitamin metabolism (vitamins K, D, A, E) because of the absence of bile to assist in the absorption of nutrients from the intestines.
What vitamin absorption increases in older adults?
vitamin A
What facilitates absorption of calcium and phosphorus?
Vitamin D plays a crucial role in facilitating the absorption of calcium and phosphorus in the intestines. It enhances the production of proteins that are necessary for transporting these minerals into the bloodstream, where they can then be utilized by the body for various functions. Additionally, factors like adequate stomach acid levels and a healthy gut lining also support the absorption of calcium and phosphorus.
