Is that ok different vitamin take same day?

Usually- it depends: There are 13 essential vitamins that our bodies need every day via diet or supplements, so if you took them individually you could take 13 diff. Vitamins each day. Most people take a multivit. And sometimes supplement with extra amounts of individual vitamins such as c, d, e and B12 as multivitamins may not have optimal amounts. This is safe as long as the total amounts are not dangerously high.
