"Fat soluble" refers to substances that can dissolve in fats and oils. These substances are typically vitamins, such as Vitamin A, Vitamin D, Vitamin E, and Vitamin K. When consumed, they are absorbed along with dietary fats in the intestines and stored in the body's fatty tissues and liver for later use. Because fat soluble vitamins can accumulate in the body, excessive intake may lead to toxicity. Unlike water soluble vitamins, which are excreted through urine, fat soluble vitamins remain in the body longer. Therefore, it's important to consume them in appropriate amounts to maintain health without risking overdose.
