Why do vitamins and mineral needn't to be digested before absorbed by vili?
For mineral, I know that they're soluble in water. Therefore it's easy to be absorbed.
For vitamins, I know not all vitamins are soluble in water.

All foods have to be broken down, separated into components, and made small enough by digestion so that body can start to absorb them. This includes vitamin tablets
Vitamins and minerals are 2 of the end products that digestion is working toward (the other 4 being carbohydrates, fats, protein, and salt water).
There are two different types of vitamins, classified by the fluid in which they can be dissolved: water -soluble vitamins (all the B vitamins and vitamin C) and fat-soluble vitamins (vitamins A, D, and K). Both are absorbed by the small intestine which takes it to the blood stream, which then transports it to the rest of the body.

Well vitamins are some fat soluble
well if you digest them, they're not digestable
why??? because it's a by product of things.
the main product is energy, not oxygen of water
that's why we don't digest by-products.
