At KefirLab, we are committed to providing high-quality, scientifically backed probiotic formulations that support gut health, immunity, and overall well-being.
As part of that commitment, we ensure transparency in how our products are made, the research behind them, and the regulatory standards we adhere to.
How Probiotics Are Regulated
Probiotics are classified as dietary supplements in many countries, including the United States and Canada.
This means they fall under specific regulatory frameworks that differ from pharmaceuticals. In the U.S., the Food and Drug Administration (FDA) oversees dietary supplements under the Dietary Supplement Health and Education Act (DSHEA) of 1994.
In Canada, probiotics are regulated as Natural Health Products (NHPs) under Health Canada’s Natural and Non-Prescription Health Products Directorate (NNHPD).
Unlike pharmaceuticals, which require premarket approval, dietary supplements do not need FDA or Health Canada approval before being sold.
However, manufacturers are responsible for ensuring their products are safe, properly labeled, and supported by scientific evidence.
The FDA and Health Canada monitor supplements through post-market surveillance, enforcing regulations on mislabeling, contamination, and false claims.
Science-Backed Claims at KefirLab
We believe in the power of probiotics, and our claims are rooted in scientific research. Every statement we make about the benefits of our probiotics is supported by clinical studies on specific probiotic strains.
While regulations prevent supplement companies from making drug-like claims (such as curing or treating diseases), we ensure that our statements about digestive health, immune function, and microbiome balance are substantiated by peer-reviewed research.
For example, studies have demonstrated that certain probiotic strains can:
- Support digestive health by promoting a balanced gut microbiome
- Help maintain immune system function
- Aid in nutrient absorption and gut barrier integrity
- Support overall well-being by influencing the gut-brain axis
Our commitment to scientific rigor ensures that we use strains with documented health benefits, based on human clinical trials, rather than general assumptions about probiotics.
Quality & Transparency
At KefirLab, we go beyond regulatory requirements to deliver the highest quality probiotics. Our products undergo rigorous testing for purity, potency, and strain viability.
We adhere to Current Good Manufacturing Practices (cGMPs) to ensure consistency and safety, and we provide full transparency regarding the strains we use and the scientific evidence behind them.
We understand that trust is earned, and we remain dedicated to offering products backed by both tradition and cutting-edge microbiome research.

Is your kefir made from grains?
We use scientific probiotic strains that originate in Centenaries Italians. That is what makes our products potent and highly effective!
why would i want the microbiome of an almost dead person? Is there science supporting this?
Hey Robert! Great observation. The latest comparative analysis of gut microbiota in Italian centenarians underscores the crucial role of specific probiotics in maintaining optimal health during aging. Our symbiotic relationship with these microbes evolves over a lifetime, with microbes adapting to meet the needs of an aging body. Understanding the microbiota’s composition is pivotal in identifying strains supportive of healthy aging. Cultivating and supplementing these beneficial bacteria becomes imperative as gut diversity declines with age, presenting challenges to our immune system. By nurturing these probiotics, we bolster our defenses, potentially enhancing longevity and overall well-being as we navigate the complexities of the aging process.

So, the source is from humans? Which part from them are being used exactly? Is using their blood involved?
No blood is involved at all. The probiotics come from a combination of traditional kefir grain cultures and science-backed strains isolated from people in excellent health. A few strains even originate from centenarians living in Sardinia’s Blue Zone—known for their longevity and gut health.
