What company is this? The high sulfate (S) in some reported cases seems strange to me, and may be a company error. I do not know that being high is a problem, but unless you are dosing huge amounts of epsom salt, it is probably coming from the salt mix and that is just how they make it.
I'm very suspicious that the magnesium is also an error unless you massively overdosed magnesium.
Nothing else jumps out, but a trace element supplement mixture might be useful. Iron and manganese, for example.
