1

Water soluble vitamins include

Vitamin C, and the B-complex Vitamins

2

Water soluble vitamins characteristics

*dissolve in water
*easily absorbed and excreted
*not stored extensively in tissue
*seldom reach toxic levels
*polar

3

Why do water soluble vitamins have higher/lower DRI's than fat soluble?

higher
because they are not stored in fat, which lowers potential toxicity due to high turnover
