Lemme is doubling down on year-round immunity.

Kourtney Kardashian Barker is launching Lemme Immunity, $30, a gummy supplement infused with a clinically studied postbiotic strain, vitamin C, vitamin D, zinc and astragalus root to boost immune function all year around. Lemme Immunity will be available direct-to-consumer on Sept. 16 and at Target on Oct. 5.

“My personal wellness routine has always been about doing the little things consistently that add up. I wanted Lemme Immunity to reflect that same idea,” Kardashian Barker said via email. 

According to Lemme cofounder Simon Huck, Lemme Immunity has been on the brand’s road map for two years and was a no-brainer to add to the assortment.

“When we think about supplements, for most people who’ve started on their supplement journey, immunity is the entry point,” he said. “For Kourtney and I, when we looked into our vitamin cabinet, we had 90 percent Lemme supplements, but we were still shopping elsewhere in the immunity category. I travel back and forth from L.A. twice a month for Lemme related things, and I’m constantly…buying vitamin C packs and other immunity products that were not Lemme. We started to speak to our community, and so many were looking for a one-stop shop for immune defense.” 

While the brand is launching Lemme Immunity just in time for cold and flu season, the product is intended for daily use, all year around. 

“We’re programmed in our head to take immunity products when we feel we’re getting sick, or as we go into flu season or cold season, when it actually is a 365 approach,” Huck said. “You should be taking your immunity product every single day to support your immune system.…We are marketing this and positioning this to people as everyday immune support.” 

The formula includes typical immune-boosting ingredients like vitamin C and D, but the patented and clinically studied postbiotic LAC-Shield is the hero. 

“Seventy percent of your immune function is in your gut, which is why it was so important to have that in our formulation,” Huck said. 

Lemme medical advisory board member Dr. Kathleen Valenton added in a statement: “What makes Lemme Immunity stand out is its use of a unique and highly researched postbiotic strain, which is an exciting area of gut and immune health science right now. It’s a smarter, more natural way to help keep your body’s defenses strong every day.”

Lemme will also expand its presence with Target by bringing this launch to the retailer. Target also carries Purr Gummies, Debloat Gummies, Sleep Gummies, Burn Capsules, Tone Gummies, Play Gummies, Fiber Gummies, Chill Gummies, Glow Gummies and Focus Gummies.

“Target has been the perfect home for Lemme and we’re proud to now be the number-one beauty ingestible brand there,” Huck said. “Launching Lemme Immunity Gummies at Target means even more consumers can easily access our science-driven formulations right where they already shop for their wellness essentials.”

As the brand has been growing, Huck said consumers are increasingly interested in different formats, which have included capsules, tinctures, chews, lollipops and gummies to date. 

“What we launched as a limited-edition was our lollipop, which is our Lemme Glow lollipop. I cannot tell you how much we hear from consumers on TikTok and Instagram that they want lollipops back from us. It’s funny because we obviously had real science and an incredible formulation, but we thought of it as a novelty offering,” he said. “We have learned that the customer is looking for those innovative formats. That’s something we are working on, and you’re going to continue to see in the next 12-to-24 months.” 

Huck added that the brand will have several new launches through the end of 2025 across women’s health. In 2026, the brand will expand its assortment with new categories and new formats. 

“I think about Lemme as a toolbox of products you can reach for at different moments in your life,” Kardashian Barker said. “Gut health and immunity are important pillars, but there’s still so much more to do in women’s health, and it feels like we are just getting started.”
