once they have been stored in tissues in the body, tend to remain there.

over time they can have too much of that vitamin present in their body,
a potentially dangerous condition called hypervitaminosis (literally,
too much vitamin in the body). Water-soluble vitamins, including
vitamins C and B, are excreted much more quickly than fat-soluble
vitamins, and they need to be replaced more frequently.</span>
