Gut Microbiome Test vs GI Test: What Each One Actually Tells You

Gut Microbiome Test vs GI Test: What Each One Actually Tells You

A gut microbiome test and a GI diagnostic test answer two different questions. Traditional GI tests look for a specific problem a provider already suspects, such as infection, bleeding, or inflammation. Gut microbiome sequencing describes the wider community of microbes living in your digestive tract and how they function. One

Why Weight Often Returns After You Stop a GLP-1

Why Weight Often Returns After You Stop a GLP-1

When people stop taking a GLP-1, research shows many of the metabolic effects start reversing within weeks, and weight often returns while lost muscle mass does not. That is biology responding to a drug leaving the system. Willpower has little to do with it. Your gut microbiome is one

The Health Check Your Annual Physical Skips

The Health Check Your Annual Physical Skips

Your yearly physical measures blood sugar, cholesterol, and blood pressure, among other markers used to diagnose disease. It does not look at broad predictive markers of health including your gut microbiome which regulates digestion, immune signaling, metabolism and more. Gut microbiome sequencing fills that blind spot by identifying which bacteria,

You Started Ozempic or Mounjaro. Here’s What Is Happening Inside Your Gut Right Now.

GLP-1 medications like Ozempic and Mounjaro slow gastrointestinal motility at all levels of the gut, like how fast your stomach empties, and that change reshapes the community of bacteria and other microbes that live in your gut. While many people will experience growth of healthy gut microbes, some people

Meet the Researcher Behind Dayhoff Health's Gut Science

When you participate in a Dayhoff Health program, your results are backed by some of the most rigorous gut microbiome research in the world. Dr. Heather Armstrong — Canada Research Chair, Associate Professor of Gastroenterology at the University of Alberta, and Dayhoff Health Clinical Advisor — has spent her career answering the

Why Elite Sports Medicine Expertise Belongs at the Center of Population Health

Dayhoff Health Clinical Advisor Dr. Guru Kandasamy, MD, Dip.Sport.Med. brings decades of precision medicine experience — treating Olympic, NHL, MLB, and CFL athletes — to the science of population-level risk identification. His clinical framework is built on one principle: early visibility produces better outcomes than reactive treatment. Who Is

Why Clinical Microbiome Testing Requires More Than a Single Sample

Why Clinical Microbiome Testing Requires More Than a Single Sample

Clinical microbiome testing requires multiple samples because the gut microbiome shifts daily in response to food, sleep, stress, and medication. A single sample captures one moment, not a pattern. Collecting samples across several days reveals which microbes are stable, which fluctuate, and what your true biological baseline actually is. Why

Why Most At‑Home Gut Tests Miss the Full Picture And What Makes Dayhoff Different: 16s vs. Shotgun Sequencing

Why Most At‑Home Gut Tests Miss the Full Picture And What Makes Dayhoff Different: 16s vs. Shotgun Sequencing

Shotgun metagenomic sequencing identifies microbes down to the species and strain level, detects fungi, viruses, and archaea, and reveals functional pathways tied to inflammation and metabolism, capabilities that 16S sequencing, used by most at-home gut tests, cannot provide. Gut health has become one of the biggest trends in wellness.

When Gut Tests Disagree: Understanding Variability in Microbiome Results

When Gut Tests Disagree: Understanding Variability in Microbiome Results

A recent article highlighted concerns about the reliability of at-home gut health tests, citing research showing that repeated tests from the same individual can produce different results. The implication is that gut microbiome testing itself may be inconsistent. But the more important question is this: Is the microbiome inconsistent
