Kaley Cuoco Passed Out For Three Hours After Testing A Supplement Intended For “Hyper” Dogs

Like any good business owner, Kaley Cuoco is dedicated to ensuring her products are of the highest quality — even if it means trying things that aren’t intended for human consumption.

In 2023, The Big Bang Theory star cofounded a pet care company called Oh Norman!, which sells everything from pet clothing to doggie dental wipes.

The brand also offers a line of “Liquid Dog Supplements,” including one called Calm the Eff Down, which is intended to help pups “manage stress” and “support a balanced nervous system.”

As stated on the packaging, the supplement contains “all-natural ingredients.” And in a new interview, Kaley revealed that she went the extra mile to prove this claim to be 100% true.

While discussing the brand’s bestselling products on The Tonight Show yesterday, Kaley told Jimmy Fallon that Calm the Eff Down — which is used to settle “hyper” dogs — works very effectively on humans, too.

“Just FYI, I did try it when we started this,” she said, explaining why she tested the dog product herself. “I wanted to make sure I could say that... I didn’t want, like, humans to, like, die.”

As for the results? “I was out for three hours,” Kaley said, emphasizing that “it works.”

Understandably stunned by the admission, Jimmy quickly interrupted to offer a disclaimer to viewers, making it clear that they’re “not recommending humans take the product.”
