EZC Pak
A product started by a doctor who sees an issue with the over prescription of antibiotics. His product, so the thought goes, should boost people's immune system so that they're sick less often so that they demand fewer antibiotics from their doctors.
This deal had some controversy surrounding it, firstly because Mark did his usual thing with calling out makers of products who also make unsubstantiated health claims but, also, because Lori accused the entrepreneur of being chauvinist and not giving her equal respect.
In the end though, it didn't stop Kevin from making a deal. This deal is being collated and will soon be posted. Check back shortly to see the details on this company and the pitch it made on Shark Tank.
