What is true about the absorption and storage of fat-soluble versus water-soluble vitamins in the body?

a. water-soluble vitamins can build to toxic levels because they circulate in the bloodstream?

The right answer is " fat soluble are stored in the liver and fatty tissue ... ".

Lipids are essentially stored as fatty acids in the cytoplasm of adipocytes. All of these cells form adipose tissue, commonly called "fat". These reserves are much larger in quantity than the reserves in the form of glycogen, in the human body.

" water-soluble vitamins can build to toxic levels ... " is false, hydrosoluble vitamins are rarely toxic, even at high concentrations, and even if they are toxic (which is very rare) is it not due to their circulation in the bloodstream, it is due to their accumulation in cells.
