Vitamins E and C can be combined with A, since the former prevents the latter from oxidizing, and C acts as an action engine for all the nutrients in this "team". With private label vitamin A you can also drink iodine, iron and zinc, and with E you can drink selenium. Iron and chromium are great companions to take with Vitamin C.

It's also worth noting the ligaments that have absolutely no effect on improving health or can be detrimental to health. These are both A/E with copper and E without the help of D with iron, since there will be low absorption of E.
