Creatine is tricky.... I never could tolerate it. Creatine is only one thing...not proteins. Some whey powders have creatine added to them, however....It is best to get the plain whey powder if you can. Read the labels some have magnesium oxide added...which often causes diarrhea. I don't know about where you are though.

Creatine should not be taken if you have any lowered kidney functions.
Also it tends to cause cramping if you are not hydrated enough, or take too much. I never got past the lowest dose..

The mixed tocoferols are fine. 400IU is all you need once a day.

If you already bought the cod liver oil, just take one cap a day.

To increase dosing use fish oil or Krill oils. Health food store sales people push that cod liver oil for some reason. Historically it was all people had in the "old" days, before fish oil was chemically developed from the fish bodies instead.
