Protected: A Guide to Water-Soluble Vitamins There are two kinds of vitamins, water-soluble and fat-soluble, and both are essential for optimal health. There are nine total water-soluble vitamins: vitamin C and eight B-complex vitamins. Water-soluble vitamins aren’t stored and pass quickly through the body, so it’s important to include them in your regular eating plan. Most of the water-soluble vitamins that are not used for essential processes are passed through your urine, though it is possible to consume too much of individual vitamins, usually through dietary supplements.
