No problem with that mix. You find many foods that come with that combination. I like to start with a good multivitamin/mineral tablet, then add supplements that I think I need more. I have a kitchen cabinet full of vitamin, mineral, herbs, etc that I take daily or occasionally at least. I've done that for decades.
For that vitamin B, if you are taking something higher than a B complex of 50mg, commonly called B50, your are wasting your money. Your system cannot use more than that, so it washed out in your urine, which will be bright yellow.
Most of the excess will be removed from your system naturally. The oil vitamins stick around a long time and can accumulate, so you should not take too much of vitamins A and E. What you are taking now, seems OK. However, you can make it easier if you find a good multi with more minerals added.
