there's an older study out there that i've referenced elsewhere, which suggests that the picolinate form is better absorbed than the gluconate or citrate forms.
zinc glycinate is supposed to be better than picolinate, which is better than zinc oxide, which is better than zinc gluconate, according to a more recent 2008 study.
so. either way, you should be fine alternating one of each each day until they're gone, and then when you buy more look for zinc glycinate.
I was taking 30mg/day of zinc glycinate for about a year and my blood test levels went down. It could just be me though. I have switched over to zinc methionine sulfate which goes by the name optizinc. I was wondering if you have any thoughts regarding that form?
