The Story Behind Kefir Lab and Its Products
How Kefir Lab began
For Erika, founder of Kefir Lab, gut health has always been personal.
Growing up in Moscow, Russia, Erika was surrounded by doctors and scientists in her family. From a young age, she learned about healthy living and the connection between the gut and overall wellness. Drinking kefir—a fermented probiotic drink—was simply part of everyday life.
But after moving to North America, she noticed something surprising. The kefir products available didn’t match the quality or functionality she had grown up with. That realization eventually sparked the idea that would become Kefir Lab.
A search for better kefir
After struggling to find kefir that met her standards, Erika began experimenting at home using a unique biomedical process her father had shared with her. She was determined to recreate the type of kefir she believed in—simple, functional, and backed by science.
Around the same time, Erika met Dario, who grew up in Tuscany, Italy. Dario was fascinated by Erika’s passion for probiotics and the gut-brain connection. His background in food and appreciation for organic ingredients made him a natural partner in the project.
Together, they began researching kefir strains and experimenting with recipes, combining Erika’s scientific perspective with Dario’s focus on food quality and flavor. The goal was simple: create a kefir product that was clean, effective, and enjoyable to drink.
Building Kefir Lab
After years of research and experimentation, Erika and Dario launched Kefir Lab to share their approach to probiotic wellness. Their products focus on simple ingredients and functional benefits, designed to support gut health as part of an everyday routine.
As the company grew, they continued refining their formulas and expanding their reach—bringing their probiotic drinks to more customers interested in digestive health and microbiome support.
Q&A with the founders
What has been your biggest success for Kefir Lab?
“Our biggest success at Kefir Lab is hearing the amazing feedback we get from our customers. Many are focused on improving digestive health and overall wellness, and hearing that we’ve positively affected people’s lives motivates us to continue pushing forward.”
What are your plans for the future?
“Next for Kefir Lab is to expand our production capacity. We want to be able to serve larger chain stores nationwide, such as Whole Foods Market and Sprouts, and heal more guts! Currently, the products are available online, for wholesale, and in stores throughout California.”
Packaging & labeling insights
As a refrigerated product, kefir presents a unique packaging challenge. Condensation and temperature changes mean labels must remain readable and durable even in cold environments.
According to the Kefir Lab team, choosing the right label material makes a big difference.
“The label material plays a big role when it comes to condensation for refrigerated products. Avery makes a custom labeling material for us which is a game-changer!”
Kefir Lab uses a combination of white squeezable matte film and white matte film labels designed to withstand moisture while maintaining a clean, professional appearance on bottles and probiotic shots.
These durable materials help ensure that branding and product information stay intact from production through refrigeration and retail display.
