The total amount of microorganisms in your body is called your microbiome. It is so important and vital that many scientists have begun to regard it as an organ unto itself. There are subdivisions of your microbiome related to specific body parts or functions, and your gut microbiome may be the most important of the bunch. 

Biohm is one of a handful of microbiome testing companies to sell tests directly to consumers. The focus of the company provides: 1. Testing to achieve an understanding of your microbiome and 2. Personalized supplements to help optimize its performance.

Biohm’s gut health tests are designed to demonstrate the make-up of your gut microbiome and to help you determine the best kind of dietary changes and probiotics to use to improve your gut and overall health. They also sell probiotic blends, prebiotics, and other supplements that they recommend to users of their test. The following report is a summary of a number of reviews of experiences with Biohm’s gut health test.

Test Results

Expect your results to be available within four to six weeks and perhaps up to seven. As soon as it’s ready, your personalized Gut Report will be available on Biohm’s website. There are four parts to the report: 1. Overall gut score, 2. Comparison to normal population levels, 3. Strain-level analysis, and 4. Personalized actionable recommendations. The documentation you receive is relatively easy to follow. Your results will show what bacteria and fungi were found in your gut microbiome and will include numerical scores. The comparison section compares the customer’s levels of the 6 major bacterial communities and 4 major fungal communities to normal levels. A breakdown of strains is also included. You will also receive diet, probiotic, lifestyle, and supplement recommendations based on your score and sample analysis though the diet and lifestyle recommendations can be on the minimal side. Biohm offers users the opportunity to purchase a package that includes a live video consult with a registered nutritionist that provides a more comprehensive break down of your results. 

The results of Biohm’s analysis may not give you a complete picture of your overall health since they are based only on bacterial and fungal DNA analysis, and the microbiome is only one part of a very complex digestive system. Therefore, to avoid unnecessary restrictions and potential nutrient deficiencies, it is recommended that consumers talk with a doctor or a registered dietitian before eliminating potentially nutritious foods from their diet.

Gut Microbiome Test and Price

The Gut Test is Biohm’s gut microbiome test. It is a DNA testing kit that allows customers to sequence the DNA in their gut bacteria and fungi. Customers also receive recommendations, based on the kinds of microbes found, for improving their digestive health. Once the lab receives the sample, it passes through quality control to ensure that there is enough sample to process. If there is not enough, the customer will be notified. Once the lab confirms the sample is enough, results typically take 4-6 weeks and based on some reviews, even a little longer. Customers will receive an email when their results are ready. They can access their report through their online gut test portal account. 

Biohm uses the extensive published scientific research of Dr. Ghannoum to understand how the abundance of different types of bacteria and fungi in your gut relates to your overall health. Biohm analyzes your bacterial and fungal makeup against the dozens of thousands of results cataloged in the American Gut Project. They also have your results analyzed by a registered nutritionist and use this information to generate personalized diet and probiotic recommendations to improve your gut bacteria and fungal diversity and overall health. This report includes foods and probiotics that could help improve the balance of the good bacteria and fungi and minimize the bad strains of each. Importantly, Biohm explicitly points out that their products are not intended to diagnose, treat, cure, or prevent any disease. If you’re concerned about any gastrointestinal symptoms or any other health concerns, you should speak to your health care provider.

The Gut Test and written recommendations typically cost $129. Customers can choose to supplement the written recommendations with a 30-minute consultation with a nutritionist. The test and the consult cost $149. This puts the cost of the test kit in the middle tier compared to competitors. Biohm is not covered by insurance although it may be eligible to be covered under HSA. The results they offer and their ability to turn those into probiotic, prebiotic, and supplement recommendations, while limited in scope, are considered by some to be a good value over some of the other gut microbiome test offerings. However, the subscription costs for the probiotic and supplement products can be substantial. Some people have experienced noteworthy differences thanks to those supplements, so it could be worth the additional costs.

More on Biohm

Biohm (Biohm health) is a health and wellness company that supports customer digestive health through a line of products that addresses both bacteria and fungi that live in the digestive tract. The company was founded by Dr. Mahmoud Ghannoum, Ph.D. and his son, Afif Ghannoum, in 2017. Dr. Ghannoum is a faculty member in the School of Medicine at Case Western Reserve University in Cleveland, OH. He has over 40 years of experience in fungus research and has been awarded over $25 million in grant funds from the National Institutes of Health to study fungi. He used his NIH funded research and expertise in the role of fungi and digestive plaques to establish Biohm to support overall wellness through optimizing gut and microbiome health.  Biohm produces an at-home gut microbiome test and numerous probiotic, prebiotic, and supplement blends. Your gut microbiome is made up of the microscopic bacteria, fungi, and other living organisms that reside in your large intestine. A healthy gut microbiome is essential for supporting gut health, and overall health.

The company allows customers to mail in a test to analyze their gut microbiome, suggests dietary changes, and recommends personalized probiotic and supplement blends to meet their specific needs based on their gut test results. You can also purchase supplements from Biohm without taking their gut health test. Biohm’s goal is to help you understand your gut and what you need to achieve overall gut health balance. With the increasing popularity of probiotics and the consumption of more whole foods, interest in balancing one’s gut microbiome has been on the rise. Something to keep in mind, the scientific and medical evidence regarding the microbiome, microbiome testing, and probiotic supplementation may not fully support all of the claims Biohm makes about what its tests and probiotic supplements can do.
