Z-12 and Growth Hormone?


I'm not sure if this question has been asked:

I've read that pharmaceutical sleep aids can impair the release of growth hormone during sleep. Does Z-12 or ZMA show any signs of impairing the release of growth hormone?

Thanks for you help.



Both of these supplements stimulate more restful sleep through natural means, so they don't impart the negative side effects associated with some pharmaceutical drugs.
