Kourtney Kardashian’s latest supplement might be her breast yet.

The reality TV star announced a new addition to her Lemme line today, offering shoppers gummy and liquid colostrum — inspired by human breast milk — to support beauty and gut health.

And for the first time ever, she’s enlisted her sister Kim to star alongside her in the new campaign — where Kim plays a full-fledged lawyer suing her big sis for not sharing the goods before releasing it to the public.

The Lemme Colostrum Gummies, $30, are made with colostrum and vitamin D3, while the Lemme Colostrum Liquid, $25, is a sugar-free liposomal creamer made with colostrum, lactoferrin (a protein found in human breast milk), immunoglobulins, MCT oil and vitamin E.

Both go on sale on the brand’s website on Thursday, November 6.
