I have been involved with Kijimea since its early days. From the outset, I was impressed by the uncompromising focus on microbiome research—translated into products that now help patients worldwide.

Kijimea K53 is formulated to support the diversity of the gut microbiome with a unique and comprehensive blend of 53 diverse probiotic strains. Kijimea K53 helps good bacteria thrive in your gut and support a healthy gut microbiome*.

The intestinal microbiome hosts trillions of unique bacteria and plays a major role in human well-being through its intimate interaction with our central body functions — from the immune system to the central nervous system. Kijimea K53 combines 53 carefully selected probiotic strains to naturally support and nurture this delicate ecosystem*. Zinc acts as further support for your immune system function*.

Gut bacteria play a crucial role in processing the food we eat and extracting valuable nutrients from it. However, highly processed foods and the modern diet can negatively impact microbiome diversity - and therefore digestion and bowel habits. Kijimea K53 contains carefully selected strains, such as L. rhamnosus IMC 501 and L. paracasei IMC 502 – clinically validated to support healthy bowel habits and intestinal regularity*.
Randomized controlled trials are the gold standard in scientific research. Our key strains have been validated in no less than 110 gold-standard trials.
