It would be a good idea to do some figuring to find out how many mg of cu and zn you’re adding now.
It doesn’t matter “what kind of copper” (well, not for this purpose), what matters for now is the number of mg provided by whatever kind of copper you’re using. Polysaccharide copper provides a different amount of elemental Cu than an amino acid chelate, if you’re comparing the same volume (1tsp or whatever)
Zinpro 40 is 4% zinc, so once you have the gm weight of what you’re using, you can know how much zn there is
It’s much better to get blood Se up to a normal range, than to try to make E make up for low Se. You can use E to make up for low Se, but it’s not ideal.
