Which of the following vitamins is classified as fat-soluble?

Vitamin D is classified as a fat-soluble vitamin, which means it is absorbed alongside dietary fats in the intestinal tract and can be stored in the body’s fatty tissues and liver. Fat-soluble vitamins play vital roles in maintaining various bodily functions; in the case of Vitamin D, it is essential for calcium absorption, bone health, and immune function.

In contrast, Vitamin C (ascorbic acid) and the B vitamins, including Vitamin B6 and thiamin, are water-soluble. Water-soluble vitamins are not stored in the body and must be consumed more regularly to maintain adequate levels. They typically function as coenzymes in various metabolic processes, contributing to everything from energy production to neurological health.
