Blank page opens

This site is not allowed to be embedded – https://www.foreverliving.com/retail/entry/Shop.do?store=USA&language=en
When I tried to embed it into the page and when I opened that page – this page was opened fullscreen (https://www.foreverliving.com/) instead of parent page where I tried to embed it.
I think it was made intentionally for nobody can embed their site (https://www.foreverliving.com/) into other sites.

Oh well… If you think there is a way around it, please let me know. Thank you!

I think it is not possible to embed this page and I don’t know how to fix it.
