Water-Soluble vs. Fat-Soluble Vitamins: A High School Nutrition Guide

📚 What are Water-Soluble Vitamins?

Water-soluble vitamins dissolve in water, which means they travel freely through the body. Because of this, they aren't stored in large amounts, and excess amounts are usually excreted through urine. This also means you need to replenish them more regularly through your diet.

📚 What are Fat-Soluble Vitamins?

Fat-soluble vitamins dissolve in fat. They are absorbed along with fats in the diet and can be stored in the body's fatty tissues and liver. Because they can be stored, it's possible to build up toxic levels if you consume too much of them.
