biotikur was created for people who want to understand their health and improve it. One of our core values is to boldly create evidence-based products through reason and science in addition to empathy for everyone's subjective experience of well-being.

In addition to conducting our own research, we’ve compiled a library of references and peer-reviewed studies from world-renowned labs and institutions as a resource for our fellow skeptics.

Below you’ll find selected studies demonstrating observed relationships between the gut biome characteristics (e.g. presence and proportion of probiotics, microbiota diversity, presence of pathogenic bacteria) and various health endpoints.

Scientific research is nuanced and dynamic. We recognize this by classifying each product based upon a review of existing research. Our evaluation criteria includes the number of studies, consistency of results, magnitude of results, and methodology characteristics.

M = Mixed. This means that some studies have shown positive results while others have been less conclusive.

E = Emerging. This means that the evidence is from pre-clinical studies, studies in rodents or studies with small sample sizes. 

S = Strong. This means there have been high-quality studies performed with positive results.

[Human] = Research, studies and trials have been performed on humans
[Mice] = Research, studies and trials have been performed on mice
[Human/Mice] = Human microbiota samples were transferred into mice to observe effect
[Review] = Researchers reviewed multiple studies/trials to arrive at qualitative judgments or conclusions
