Fat-soluble vitamins are absorbed through the intestinal tract with the help of lipids (fats). Because they are more likely to accumulate in the body, they are more likely to lead to overdose diseases than are water-soluble vitamins.
Insulin is protein soluble and would be unable to cross the wall of the gastrointestinal tract without being broken down and the hormones in birth control pills are lipid soluble are correct.
Any excess vitamins that your body hasn't absorbed but that are water soluble leave your body in your urine.
Solubility refers to the ability of a substance to dissolve in a particular solvent. Most vitamins are soluble in either water or fats. fats soluble vitamins cannot be dissolved in water and require mixture with oils or fats in order to be used by the body.
Vitamins in particular come in two particular varieties. They can be water soluble; B and C. Or they can be insoluble like A,D,E, and K.
Body has got very large reservoir of fat, in which very large quantity of fat soluble Vitamins can be stored. Body has no mechanism to excrete these fat soluble vitamins as fat does not come in contact with any excretory organ like a pair of kidneys. It is stored in fat cells. If you give excess of water soluble vitamins, then they will be excreted by pair of Kidneys. Pair of kidney filters out about 180 litres of fluid/ day and through this excrete water soluble vitamins. Now it is easy to understand that why water soluble vitamins are not stored in body.
Fat does not absorb Vitamin B-Complex as they are water soluble Vitamins. Fat absorb and can store enormous quantity of Fat soluble Vitamins like Vitamin A Vitamin D, Vitamin E, Vitamin K.
The B2 (riboflavin) is what makes pee yellow. Since B vitamins are not stored in the body (water soluble) any extra is lost in your urine. The bright yellow would happen to anybody taking the same vitamins.
