Kourtney Kardashian’s Milk Gummies Are Made in Israel - And They're Selling Like Wildfire

The Kardashians, particularly Kourtney Kardashian Barker through her wellness brand Lemme, have recently promoted a colostrum-based supplement line that's generated buzz for its gut health and beauty benefits.

What Is Colostrum and Why the Hype?

Colostrum is the nutrient-rich "first milk" produced by mammals (including cows and humans) right after giving birth. It's packed with antibodies, proteins, growth factors, vitamins, and minerals that support immune function, gut health, and tissue repair in newborns.

In supplement form, it's typically derived from bovine (cow) sources and has gained popularity among adults for potential benefits like:Immune support: High in immunoglobulins (e.g., IgG) that may help fight infections and inflammation.

Gut health: Aids digestion, reduces bloating, and promotes a balanced microbiome by strengthening the gut barrier.

Skin, hair, and beauty: Some users report improvements in skin elasticity, hair growth, and overall radiance due to its protein and growth factors.

Athletic recovery: Supports muscle repair, joint health, and reduced fatigue, especially for women athletes dealing with hormonal fluctuations or bone density concerns.

While early studies show promise (e.g., for gastrointestinal issues and exercise performance), experts note that more large-scale human trials are needed, and it's not a miracle cure. It's generally safe for most adults but could cause issues for those with dairy allergies or lactose intolerance.

The Product: Lemme Colostrum Gummies and Liquid

Launched on November 4, 2025, by Kourtney's brand Lemme, these are the supplements tied to the Kardashians. They're positioned as an "easy daily ritual" inspired by the nourishing power of breast milk, but using ethically sourced bovine colostrum.

Colostrum Gummies ($30 for a bottle): Chewable, berry-flavored with 500mg of colostrum isolate per serving, plus vitamin D3 and prebiotics. Clinically studied to support gut health, debloating, and digestion. Heat-stable, so ideal for on-the-go.

Colostrum Liquid ($25 for a bottle): A sugar-free, liposomal formula (for better absorption) that can be mixed into drinks like coffee or water. Includes lactoferrin for added immune and anti-inflammatory perks. Users rave about it as a creamer alternative that improves digestion.

Both are plant-based in formulation (despite bovine sourcing), odorless, and designed for women-focused wellness, aligning with the "femme" angle. They're available on lemme.com and select retailers.

The Israeli Connection: Maolac's Role

The star ingredient is Maolac colostrum isolate, developed by Maolac, an Israeli startup founded in 2021. Maolac specializes in biofunctional proteins extracted from surplus bovine colostrum (a byproduct of the dairy industry) and engineered to mimic the protective proteins in human breast milk, making it more bioavailable and effective for humans than standard colostrum.

Their technology uses AI to match cow colostrum proteins to human ones, removing unwanted elements like growth factors while boosting anti-inflammatory activity (up to 7x more effective than traditional bovine colostrum).

Key Maolac products include:

Maolactin GI: For gut health, reducing symptoms like bloating and promoting microbiome balance (backed by a double-blind study).

Maolactin FMR: For muscle recovery, joint support, and mobility, aimed at athletes and seniors.

Maolac's innovations stem from Israel's strong biotech scene, focusing on sustainable upcycling of dairy waste. No direct "femme" branding, but their colostrum is tailored for women's health applications, like hormonal balance and beauty.

Lemme partnered with Maolac to incorporate this Israeli-sourced isolate, giving the product its "from Israel" tie-in.

The Kardashians' Involvement and Promotion

Kourtney, who launched Lemme in 2022, has positioned colostrum as her latest "secret" for post-pregnancy wellness, drawing from her own experiences with breastfeeding and gut health.

The rollout featured a hilarious campaign video where Kim "sues" Kourtney in a mock courtroom for not sharing the product sooner, playing on their famous sibling rivalry. It's gone viral on TikTok and Instagram, with millions of views, and fans love the self-aware humor.

Khloé and others in the family have indirectly boosted the trend through their wellness endorsements, though Kourtney and Kim are the main faces here. Still, sales have spiked, with users reporting better digestion and energy.
