Q 4 : Do we need vitamin supplements? what are the functions of vitamin A,B,C and E?

I know this question the answer is certainly YES ! because vitamin is needed by our body everyday.(perhaps it has been a common sense )
from the internet I know there are 13 different vitamins that can be divided into two categories: water-soluble and fat-soluble.
Vitamin A is function the growth and repair of body tissue and keeping the body's skin and mucous membranes healthy including the linings of the airways and the digestive tract.
