This review is written with the intent to be as unbiased as possible. However, it represents the opinion of an individual reviewer and is therefore subjective. Furthermore, at Nebula Genomics we seek to educate the public about the benefits of Whole Genome Sequencing. Information about our Whole Genome Sequencing DNA test is therefore incorporated into the review.

Review of the Science Behind OlaWell

OlaWell sequences over 50,000 different bacteria in the gut microbiomes to provide actionable information about an individual’s food tolerance. The microbiome is a collection of millions of bacteria in the human body and is a complex ecosystem involved in many different metabolic, immune, and energy conversion processes.

Food intolerance is the difficulty in digesting certain foods, causing symptoms such as stomach pain, bloating, diarrhea, skin rashes, and itching. Research suggests that an abnormal gut microbiome can increase food intolerance while maintaining a healthy gut microbiome can decrease these effects. It may also be important for overall wellness.

On its website, OlaWell uses the example of the Japanese, who typically have much longer lifetimes (100+ years) than those in western nations. Although there are a number of factors contributing to that statistics, experts believe their diet is a key component. They also tend to have extremely low risk of heart disease, most cancers, Alzheimer’s disease, and obesity

OlaWell compares customers’ initial microbiome profiles against established profiles from ideal diets, like the Japanese one. Using this information as a baseline, the company makes dietary recommendations designed to shift the customer’s microbiome profile closer to the ideal. A proprietary algorithm drives the computation of these recommendations.

Review of OlaWell Products

The main OlaWell product is the Gut Check plan that includes a single kit used to test gut microbiomes. Customers get a customized report with recommendations based on their test results. The Wellness Subscription plan adds additional reports related to a healthy life.

Review of OlaWell Gut Check

With OlaWell’s food intolerance test kit, users receive gut microbiome analysis and profile. The kit is used once. The test provides users with an intolerance profile for more than 200 food substances. This helps users find relief from digestive symptoms caused by food intolerances without tracking everything they eat.

Food recommendations are divided into three groups and the report also includes lactose and gluten intolerance information with specific details and recommendations. The test provides users with a plan that would help them create a balance between their health and eating habits and may recommend avoiding these substances entirely.

Review of OlaWell Wellness Subscription

This service further guides users on what they should eat and how they can maintain stable health with a minimal change in diet.

OlaWell Wellness Subscription

With an OlaWell wellness subscription, users get access to an additional level of analysis and wellness insights. For instance, users who subscribe get personal food recommendations that are more impactful through analysis of two conditions instead of one. Customers can choose from weight, digestion, mood, or immunity management.

The subscription also covers testing every 6 months so that customers can track their progress.

Review of Taking the OlaWell Test

Users should follow the included directions for how to collect and process a sample for the test. Generally, users will take a fecal sample by using the swab to collect a small amount of material from used toilet paper after the first bowel movement of the day.

Review of OlaWell Report

The OlaWell report is designed to be actionable and easy to understand. Once you have submitted your sample to the company, wait for the report to be sent to your device.

Results summary and details

The first part of the report shows a results summary with the most important numeric values.

OlaWell sample report result summary

The numbers are color coded for easy recognition with green being good, yellow being moderate, and red being bad or needs improvement.

The next sections of the report provide detail on the three major pieces of information given in the results summary.

Diet Microbiome Score: This score shows if you have been having a balanced meal based on your diet choices. A score of 25 to 75 means that your food choice is not balanced. The lower the score, the worse your diet imbalance.

Sample report diet microbiome score

A score from 75 to 100 is an acceptable to excellent food range balance. The higher the score the better your food balance for your gut.

Gut Microbiome Composition: This provides a score on your gut microbiome composition ranging from Critically Low to Balanced to Critically High. The two ends of the score spectrum are very bad, while the balanced is the best position. Your report will show your category for each bacteria tested.

Food Intolerances: This is where you will find the 200+ food and food ingredients tested for whether they negatively influence your gut microbiome balance. From here, you can designate items to place on your digital shopping list.

Sample report food recommendations

Each food is categorized as Good, Acceptable, or Bad.

Review of OlaWell Other features

The next part of the report highlights the popular food intolerances of lactose and gluten.

Sample report lactose intolerance

A low score below 50 means that your gut microbiome has a low ability to digest the material. The higher the score, the better the gut microbiome can digest either lactose or gluten.

The report also suggests five foods that improve the levels of bacteria that digest lactose and gluten.

Customers can receive their raw data as FASTQ and CSV files upon request.

Nebula Genomics

OlaWell is a microbiome testing company that specializes in food sensitivities. Its aim is to help users understand their gut health and choose foods that best support their optimal diet. The company uses a proprietary AI system to create recommendations based on current microbiome population and the world’s best diets.

To identify the gut bacteria, OlaWell uses microbiome sequencing. If you’re thinking that you want to explore your genome, you may be interested in Whole Genome Sequencing. 

Nebula Genomic uses 30x whole genome sequencing technology to decode all 20,000 genes in the human genome. Results also come with ancestry reporting and genome exploration tools.

Nebula is not a microbiome company and thus does not report on gut microbes. However, it offers a comprehensive test for any genetic predisposition related to disease, traits, and health. This includes issues that may be causing your digestive issues. We also provide customers with regularly updated reports on the latest genetic discoveries. 

For only $299 or less, customers will get access to their entire genome, allowing you to continue to ask more questions as more research is conducted.
