New Products and Ingredients

Both products became available on the brand’s website on Thursday, November.

Campaign Features Kim Kardashian as Lawyer

For the first time, Kourtney collaborated with her sister Kim Kardashian in a humorous ad campaign. In it, Kim plays a lawyer suing Kourtney for not sharing the supplement before its public release.

“I’ve taken colostrum for years because it’s amazing for gut and immune health, but I wanted to make it easier for everyone to enjoy,” Kourtney shared with The Post. “Some people love the simplicity of a gummy, while others want to add it to their matcha or coffee, so we created both.”

The new campaign hints that Kourtney might have been keeping the benefits of colostrum a secret from Kim.
