Zinc supplement?

[Gropo]

I'm brewing a partial mash DIPA this weekend with some cultured 1056 from the local brewery. Was planning on adding a little Fermax @ 15 minutes. I also immerse my copper chiller @ 20 minutes. Would a zinc addition help? If so when, and what is the best type of zinc supplement is best? (I'm leery of store-bought zinc supplements because of all the other crap that's probably in there). Thanks. Oh, and I oxygenate the wort with a sintered stone too.

The absolute best thing you can add to the boil is some dead yeast. They have 100% of the nutrients that yeast need to grow.

And I believe that Fermax contains dead yeast. Thanks.
