Which vitamin interacts with aluminum-containing antacids and affects chemotherapy effectiveness?

• A. Vitamin K
• B. Ginkgo biloba
• C. Vitamin E
• D. Vitamin C

Answer: (A)

Aluminum-containing antacids can bind with fats and fat-soluble vitamins in the gut, reducing their absorption. Since vitamin K is a fat-soluble vitamin, its absorption can be diminished by these antacids. In older adults receiving chemotherapy, maintaining adequate vitamin K is important because chemotherapy can cause clotting or bleeding risks through thrombocytopenia and mucosal injury. If vitamin K absorption is impaired, coagulation status may be affected, potentially complicating chemotherapy management and safety. Ginkgo biloba and vitamin C are not fat-soluble vitamins and are less directly tied to this specific antacid interaction. Vitamin E is fat-soluble like vitamin K, but the clinical emphasis in this context is on vitamin K due to its direct role in coagulation and the bleeding risks that can intersect with chemotherapy.
