Which vitamin is fat-soluble?

• A. Vitamin D
• B. Vitamin C
• C. Vitamin B12
• D. Vitamin B6

Answer: (A)

Fat-soluble vitamins are absorbed with dietary fats and can be stored in the liver and in fat tissue for later use. Vitamin D fits this group. After you consume fat, bile helps emulsify it, enabling vitamin D to be absorbed into intestinal cells and then carried to the liver and fat stores for later use. It also acts as a hormone that helps regulate calcium and phosphate, which is key for bone health. Because it’s stored in the body, you don’t need to consume it every day, but taking in too much can lead to toxicity. In contrast, the other listed nutrients are water-soluble and aren’t stored in the body to the same extent; they’re typically excreted in urine and require more regular intake to prevent deficiency.
