Which of the following are fat-soluble vitamins?

1. Vitamin B1, B2, B3, and C

2. Vitamin A, D, E, and K

3. Vitamin K, C, and E

4. Vitamin A, B6, and Folate

The correct answer is: Vitamin A, D, E, and K

Fat-soluble vitamins are a group of vitamins that are soluble in fats and oils. They are stored in the body’s fatty tissues and liver, which allows the body to use them over time. The vitamins that fall into this category include vitamins A, D, E, and K. These vitamins serve various essential functions in the body. For instance, vitamin A is important for vision and immune function; vitamin D aids in calcium absorption and bone health; vitamin E functions as an antioxidant; and vitamin K plays a crucial role in blood clotting and bone metabolism. Since they are stored in fatty tissues, it is possible to accumulate them in the body, which is why it’s essential to manage their intake to avoid toxicity. The other options listed contain vitamins that are either water-soluble (like the B vitamins and vitamin C) or are not categorized correctly. Water-soluble vitamins are not stored in significant amounts in the body; instead, they are excreted through urine, making their regular intake crucial for health. This distinction is important in understanding dietary requirements and potential deficiencies or toxicities related to different vitamin types.
