I have a quick question about supplements?

i just have to ask something about taking some supplements. i take, spring valley natural magnesium,, nature made calcium with vitamin d 600mg, one a day teen advantage, Meijers chewable vitamin c 500mg, and nature made vitamin e is this bad for me? i also weigh 151lbs if this matters at all. thank you! (i take one a day of all of these) except for the magnesium because your supossed to take 3 a day and those 3 equals the 100% daily value of magnesium!
