SynForU-ReMain is a patented, clinically studied probiotic formula developed by SynbioTech for kidney and long-term metabolic health. It works through the gut–kidney axis, helping to lower the body’s burden of gut-derived uremic toxins, support kidney function, and address oxidative stress and compromised intestinal barrier integrity associated with declining renal health. For brands, it offers a microbiome-based formulation concept positioned around proactive kidney and metabolic health.

Why kidney health, and why now

Kidney function declines slowly and quietly, often from as early as age 30, and much of that decline is driven by toxins that begin in the gut. As awareness grows that the gut and kidney are biologically linked, microbiome-based nutrition offers a proactive way to reduce toxin accumulation and help preserve function over time.

A two-strain formula, built for the gut–kidney axis

SynForU-ReMain combines two Lactobacillus strains selected for their ability to clear the gut precursors of uremic toxins and support a healthier gut microbial community:

• Lacticaseibacillus paracasei LPC1411 (MFM 18), formerly Lactobacillus paracasei
• Lactiplantibacillus plantarum LP1410 (MFM 30-3), formerly Lactobacillus plantarum

Both strains were screened for their capacity to absorb and reduce indole and p-cresol, the gut precursors of the uremic toxins indoxyl sulfate and p-cresyl sulfate.

How SynForU-ReMain supports kidney health

By restoring gut balance and supporting intestinal barrier integrity, the formula acts across several complementary pathways. Its proposed mechanisms include:

• Reduce the gut-derived uremic toxins that burden the kidney, such as indoxyl sulfate and p-cresyl sulfate
• Support kidney function and long-term metabolic stability
• Strengthen the gut barrier to limit toxin translocation into the bloodstream
• Restore antioxidant defense against the oxidative stress of kidney decline

Research and recognition

SynForU-ReMain is supported by four peer-reviewed publications, including a human clinical pilot in kidney-transplant recipients and cross-species (feline) evidence, is protected by invention patents in Taiwan and the United States, and has earned multiple international invention awards between 2022 and 2025.

Formulation & product applications

SynForU-ReMain can be formulated into pre-blend powders, stick-pack sachets, and capsules, with a typical daily serving of around 10 billion CFU. It is intended for food and dietary supplement concepts positioned around proactive kidney and metabolic health.
