Which one works in my sentence below: all these or each of these?

"Since it is difficult to measure all these antioxidants individually/ each of these antioxidants individually, the plasma total antioxidant capacity (TAC) would be evaluated."

    It makes more sense to use “all” with “individually”.

    “Each” automatically means individually so risks sounding a bit odd.

    You don't really need either. 'Individually' on its own appears to be enough to convey the meaning. It rather depends on what came before.
