Is it possible to take different types of vitamins during the day, e.g. magnesium with vitamin B6, iron and a dietary supplement for hair?

You can use different types of preparations, but you should analyze their composition so as not to take too much, for example, one vitamin, which appears in 3 different products. In addition, iron should not be taken at the same time as magnesium, calcium or zinc, because it will not be absorbed in the company of these minerals. For the same reason, you should not combine iron with a meal containing dairy, coffee and tea. An interval of at least a few hours should be maintained, and it is best to take at other times of the day. Iron can be taken together with vitamin C, which improves its absorption. Magnesium should also not be washed down with coffee and tea. Dietary supplements should be taken with or after a meal (taking into account the above recommendations) to avoid stomach irritation. https://www.gdziepolek.pl/tematy/magnez-co-ma-do-niego-kawa-stres-i-wit-b6/opinie-i-pytania
