Exclusive: Kourtney Kardashian Launches Supplement Inspired by Breast Milk

Kourtney Kardashian recently spoke with The Post about her newest addition to the Lemme supplement line, introducing colostrum-based products inspired by human breast milk. This launch marks a unique blend of beauty and gut health support, available in gummy and liquid forms.

New Lemme Colostrum Supplements

The supplements became available on the brand’s website starting Thursday, November.

Campaign Featuring Kim Kardashian

For the first time, Kourtney enlisted her sister Kim Kardashian to star with her in the campaign. In a playful twist, Kim plays a lawyer suing Kourtney for not sharing the supplements before their 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.”

The promotional video humorously hints that Kourtney may have been keeping the benefits of colostrum from her sister.
