PMDD constiuency

I find it rather difficult to obtain the Chelated Trace Element mix, however, 
have managed to pursuade a chemistry student to make up the formula for me, 
provided I purchase the necessary chemicals.
Can someone post the necessary chemicals for making the Trace element mix
 eg.  Ferrous Sulphate, Boric acid etc.
and in the required amounts (eg. 1 tsp etc)

Thanks very much,
