Why are some vitamins soluble in water and some soluble fats?

The human body treats most vitamins as a well -stocked drug box; Each “bottle” remains safely stored until it is needed as a catalyst or carrier for other basic chemicals. In fact, only a very small amount of vitamins is necessary to maintain a healthy body, so any excess should be excreted from the body over time. Some vitamins, such as complex B and C, are considered soluble in water, which means they dissolve in the bloodstream and eventually excrete through the urinary tract. Others, such as A, D, E and K, are considered soluble fats, which means that they will be stored in fat cells or liver and eventually excrete by the lymphatic system. Water soluble vitamins such as complex B and C are essential for short -term projects such as increasing the nervous system or providing antioxidants for cell repair. Once the body has gained enough vitamins soluble in water to perform tasks at hand, there is no need to store the remaining supply. Excess vitamin C and B complex B are filtered from the bloodstream by the kidneys and are excreted in the urine. That is why it is sometimes more difficult, even if it is definitely not impossible, overdose of vitamins soluble in water than for the vitamins soluble in fats.

On the other hand, the fat -soluble vitamins are processed in a different way. Vitamins, such as A, D, E and K, usually survive the initial digestive process and enter the lower intestines where they are absorbed and dissolved by fat cells called lipids. Some of these lipids depositing vitamins eventually reach the liver or other fat deposits for long -term storage. Vitamins of soluble fats help other chemicals and nutrients of Peúkoly Rorm, such as calcium absorption or collagen replacement. The body needs only a small amount of fat -soluble vitamins, but the excretion process takes much longer. Fat cells literally MusIm melt to get rid of excessive fat -soluble vitamins and relax vitamins slowly through the lymphatic system.

It is possible to consume a toxic level of soluble fat vitamins through an overdose with a supplement or a long -term unbalanced diet. Eating too many water -soluble vitamins, such as vitamin C, can also cause serious health problems, but these vitamins can be quickly eliminated through the urinary path. The fat -soluble vitamins must be stored in the liver until they can safely metabolize, so it is important to avoid extreme doses of vitamins A, D, E or for their supposed health benefits. The body only needs trace amounts of fatty soluble vitamins at the same time, so overdose can be quickly toxic.
