Kourtney recently launched a range of mood-boosting gummies, adding another business venture to the Kardashian-Jenner family empire.

Last month, Kourtney revealed her new pursuit after weeks of teasing fans about what was to come.

Lemme, vegan and gluten-free, offers consumers three vitamin options: Lemme Matcha, Lemme Chill and Lemme Focus.

She recently wrote on Instagram: “Finally let me share what I’m up to! I’ve dreamed about this idea, had many, many, many meetings and conversations with different people to figure out how best to build this, the right partners and building the team that feels really good.’

Adding: “Once it finally got right, it all went with ease. Lots of hours, zooms, reverie, but all with quick determination and real fun! Finally, 5 years later, my passion/work baby is finally born.”
