FoodMarble wants to help those suffering from chronic gut issues including IBS, IBD, chronic constipation, and SIBO/IMO. They initially created a device to help people find the foods that best suit their unique digestion. This is achieved by tracking how their hydrogen levels change in response to the food they ate. You can also get a FODMAP intolerance kit that can help you figure out your tolerance to some of the most common FODMAP sugars (lactose, fructose, inulin and sorbitol). The device pairs with a handy app that records all your data so over time, you can see the trends.
FoodMarble didn’t stop there, more recently they added methane, which is vital for those who want to monitor SIBO/IMO, as well as constipation. The coolest thing about this device is, that you can test your response to your regular diet or even track how you are responding to any supplement you might be taking, as often as you need. Each of us has a unique response to diet and supplements, so what works for one, might not work for the next.
