Tea is an astringent substance rich in tannin (polyhydric alcohol) that binds all available substances and they are not absorbed (this same property is effective in case of poisoning). Therefore, all medicines, including vitamins, are not recommended to be taken with tea. Coffee is rich in all kinds of acids and bases, which also have astringent properties.
Now, specifically about vitamins and minerals. For a good assimilation of vitamins and minerals, there must be an effective combination of them; it is not permissible that one tablet contains the daily dose of all vitamins. Minerals and vitamins will react with each other and are neutralized, then they will react in the liquid medium of the body and are also neutralized. As a result, assimilation will be 10-20%. The fat-soluble vitamins ADEK require fat. For B vitamins, this condition is not necessary.
Vitamins will pass through your body in transit without being absorbed by your body. You need fat to absorb vitamins. There are a number of essential vitamins that we must get on a daily basis, but their absorption and absorption process will not be possible without the presence of fat. Vitamins A, C, E, and K are fat-soluble vitamins, which means that they are absorbed and absorbed only when fat is present. So in addition to juices, tea, and coffee, drink melted fat if you avoid solid foods.
