Cyclo ZMA

I saw a cyclo-dextrin Zma product the other day, any opinions on this? If this really did work, would it eliminate the need for an empty stomach, since it would no longer be absorbed through the stomach?

It cannot work. There is no way one could
deliver 50 mg or any amount like that sublingually with cyclodextrins or any other reasonable method.

Besides this, there is no issue with needing to take ZMA or any zinc supplement on an empty stomach, nor of needing to avoid calcium at the same time. Life on Earth has existed for billions of years getting zinc and calcium at the same time, and it’s actually easy to get too much zinc from supplements, including plain old zinc oxide, rather than being almost impossible to get enough.
