Fat Soluble Vitamins vs. Water Soluble Vitamins
Key Differences
Fat Soluble Vitamins
Vitamins that can be stored in our human body is called as fat soluble vitamins. Vitamins A, D, E and K are fat soluble vitamins. Fat soluble vitamins dissolve in fat and are stored in liver and fat tissues until they are needed. Fat soluble vitamins cannot be easily excreted from the body except vitamin K, so they are toxic if taken in excessive amounts. Absorption of these vitamins totally depend upon efficient fat intake and absorption. In healthy individuals, eating a normal and healthy diet will not lead to toxicity of these vitamins. Vitamin A also known as retinol help eyes to adjust in light changes also vitamin A play role in bone growth, reproduction, regulation of immune system and cell division. Vitamin D can be obtained through sunlight and it helps in absorption of calcium from small intestine which then absorbs in our bone and make them stronger. Vitamin D in children is essential for the development of stronger bones and healthy teeth. Vitamin E acts as an antioxidant which protects vitamin A and C, RBCs, essential fatty acids from destruction. Vitamin K is produced by bacteria that are present in our gut, it helps in normal blood clotting, production of proteins for blood, bones, kidneys and promotes bone health.
Water Soluble Vitamins
Those vitamins which cannot be stored in our body are called as water soluble vitamins. Vitamin B-complex and vitamin C are water soluble vitamins. Water soluble vitamins are dissolved in water and eliminated in urine. So, we require continuous daily supplement of these vitamins in our diet. Vitamin B-complex is divided into eight groups: vitamin B1 or thiamine is important for maintaining our nervous system, it also helps to release energy from food and it promotes normal appetite. Vitamin B2 or riboflavin promotes good vision and healthy skin. Vitamin B3 or niacin helps in normal enzyme function, promotes healthy skin, normal appetite and nerves. Vitamin B6 or pyridoxine aids in protein metabolism and formation of RBCs. Folic acid promotes RBCs formation. Vitamin B12 or cobalamine aids in building of genetic material. Biotin aids in metabolism of fats, protein and carbohydrates. Pantothenic acid helps in the formation of hormones. And last Vitamin C or ascorbic acid, it helps in the formation of collagen, a connective tissue that holds muscles, bones and tissues together.
