What are the two types of vitamins?

The classification of vitamins into two groups, water-soluble and fat-soluble, is fundamental in understanding their absorption, transport, storage, and function in the body.

Water-soluble vitamins, which include the B vitamins and vitamin C, dissolve in water and are not stored in large amounts in the body. This means they need to be consumed regularly in the diet, as excess amounts are typically excreted through urine. These vitamins often play crucial roles in energy production, red blood cell formation, and maintaining good health.

Fat-soluble vitamins, on the other hand, include vitamins A, D, E, and K. These vitamins can be stored in the body’s fatty tissues and the liver, allowing for a larger reserve that doesn’t require daily intake. They are absorbed along with dietary fat and play vital roles in processes like vision, bone health, and blood coagulation.

The other choices do not accurately reflect the scientifically accepted classification of vitamins, thus reinforcing that the correct answer about the two types of vitamins is indeed water-soluble and fat-soluble.
