The two types of vitamins are fat-soluble vitamins and water-soluble vitamins.
a) Fat-soluble vitamins: They include vitamins A, D, E and K. They are stored in the fat tissue of our body and are used when needed by the body. Our body can synthesise vitamin D in the presence of sunlight.
b) Water-soluble vitamins: Vitamin B complex (vitamins B1, B2, B3, B6, B12 and folic acid) and vitamin C are water-soluble vitamins. These are not stored in the body and are needed to be regularly supplied by consuming food items such as spinach, green vegetables and citrus fruits.
