The ketosis breath tester saves you stitches in the finger and the device can be used repeatedly by replacing the mouthpiece, saving you money on the test as you no longer have to buy test strips.

The ketone breath tester is calibrated to detect acetone concentration and ensure you get consistent and accurate results, which is extremely effective for people following a ketogenic diet.
Please note: there is a time delay before your ketone levels drop after eating carbohydrate-rich foods, which is why you may still get high levels afterwards. The time span is different for each person and also depends on how long you have already lived ketogenically.
