Campaign Featuring Kim Kardashian

For the first time, Kourtney's sister Kim stars alongside her in the new advertising campaign. In the humorous promo, 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 told 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.”
