Question

Why is there no enzyme to digest vitamins?

Answer 1

Vitamins are used in their original form by the cells. They do not require digestion. They are absorbed directly from the digestive tract, transported by the blood to the cells, and the cells absorb and use what they need.
Because vitamins are absorbed by the body 'as is' - not broken down and digested.

Answer 2

There are no enzymes in our body to digest vitamins because they are absorbed directly from the digestive tract and moved by the blood to the cells.
