Visualizing Gut Health: Launching a 'Gut-Activity Test Kit' as a Gateway to Better Eating Habits

RESET, a food brand from Yamagata Prefecture with the theme 'The joy of emptying, the joy of filling' (Operated by ALFOR Inc.; HQ: Sakata, Yamagata; CEO: Yohei Ikeda), will release the 'Gut-Activity Test Kit' on April 3, 2026, allowing users to check their gut health at home. This kit is a healthcare service that supports the first step toward improving eating habits by visualizing the state of the gut environment through the measurement of 'indoxyl sulfate' (a putrefactive substance produced by gut bacteria) in urine. In addition to checking gut status against national averages, the service provides rank assessments and lifestyle improvement advice, allowing users to objectively understand their gut environment. Furthermore, after checking the results, users can utilize a gut-health recipe diagnostic and a 14-day gut-health program via LINE, supporting daily dietary improvements.

Improving Eating Habits by Knowing Your Gut Health: In recent years, the term 'Gut-Activity' (腸活) has become widely known, leading to dietary habits conscious of gut health, such as consuming fermented foods and dietary fiber. However, there are few opportunities to objectively know 'what state my gut environment is in' or 'if my current diet suits my gut.' The RESET Gut-Activity Test Kit provides an opportunity to grasp one's physical condition by visualizing the gut environment through the measurement of urinary indoxyl sulfate. By adopting a testing method that uses urine instead of stool, it is designed to be easy to use.

RESET emphasizes a 'design that is easy to tackle' in its fasting programs. This kit is also positioned as an 'entry point' for organizing eating habits. Starting with knowing one's own condition, it leads to 'choices for organizing,' such as reviewing meals and fasting.

After the test, users can use the gut-health recipe diagnostic and the 14-day gut-health program via LINE. By simply answering questions, users receive a recipe diagnostic tailored to their diet and preferences, and engage in a 14-day program based on about 30 recipes supervised by a registered dietitian and a former French chef. It is characterized by providing consistent support from knowing the gut environment to improving eating habits, rather than ending with just the test.

What can be checked: The test measures the amount of indoxyl sulfate in urine. Indoxyl sulfate is a substance produced in the body by the action of gut bacteria and is considered an indicator that tends to increase when the gut environment is disturbed. Based on the results, users can check: Trends in gut environment, comparison with national averages, gut status rank, and lifestyle improvement advice. (Note: This test is a healthcare check for lifestyle review and is not for diagnosis, treatment, or prevention of disease.)

How to use: 1. Apply online, 2. Collect at home, 3. Mail in the post, 4. Check results online, 5. Register on LINE, 6. Recipe diagnostic, 7. Start 14-day program.
