As far as aquiring it....anywhere you can find vitamins.

EDIT: I did some googling and found this on zinc:

0.1-0.3mg/l and up to 0.5 mg/l being maximum
The key to adding zinc is to be careful of the form that it is added in. Simply adding ZnCl2 or ZnSO4 in the appropriate concentrations will not work (unfortunately) since it will be absorbed into the trub. You need to add a biologically abundant form of zinc...a zinc chelate like Zinc citrate or Zinc gluconate.

More details can be found in Bromberg, Susan K, et al. Requirements for Zinc, Manganese, Calcium, and Magnesium in Wort. JASBC, 6/11/97.

just quick question most commercial nutrient i saw over net just selling diammonium phosphate as yeast nutrient but in your formula compare to diammonium phosphate, you added massive size of "grams of ammonium sulphate" to be exact 747 gram! compare to 40gram of diammonium phosphate.

can you explain what the benefit of this over those please.

thank you

If you can't find chemical type nutrients how about boiling up some bread yeast hulls or adding fruit, fresh or dried. Either should help a primary go alittle faster.
