How BIOSENSE™ Works

Behind The Technology

The required deep lung sampling process provides accurate and reproducible measurements by correcting for natural variations in exhalation time and lung capacity across individuals.

BIOSENSE™ is the only breath monitor to provide this patent-pending technology. Clinical data shows a high full-day correlation between blood and breath ketones.

Fat Burn

Only BIOSENSE™ provides a full daily picture of the depth and duration of your ketosis, so you can see your true, fat metabolism rate.

Accuracy

The BIOSENSE™ patent-pending deep lung sampling technology, together with an individual factory calibration process, ensures that every device delivers precise breath ketone measurements.

Personalization

BIOSENSE™ lets you set a personalized goal for your daily time and depth in ketosis, represented by the BIOSENSE™ Ketone Score. This is important because research suggests that a daily Ketone Score of 120 is associated with fat loss.

Measuring ketone production can be a pain. I’ve recently been testing a new device called BIOSENSE™ that will change this. It’s a scientifically validated, highly accurate breath ketone monitor that makes it easy to test your ketones throughout the day. I’m now recommending it to all of my patients that are fasting or doing ketogenic diets, and I’m using it myself. Check it out!

I enjoyed using BIOSENSE™ since I was able to truly see my numbers rise each day as I got deeper into ketosis. It really helped to hold me accountable as well. For example, I had one sugary alcoholic beverage and it took me way out of ketosis and my numbers dropped significantly. This actually helped me because it showed me that even one drink can knock you out of ketosis if it isn't within the keto diet options.

The BIOSENSE™ device made tracking my ketones easy and accurate compared to taking multiple blood samples during the day. It was so convienent I could use it at my desk at work. As an endurance athlete training for an Ironman, the BIOSENSE™ device helped me maximize my training by staying in a fat burning state throughout the day. It helped me easily track my ketones and help keep me focused on my diet so I could excel on my daily workouts.
After being on a ketogenic diet for two years, the BIOSENSE™ device validated my diet choices so I could more easily stay in ketosis.

I love this product! BIOSENSE™ is easily the most affordable, accurate and pain-free keto tester that I’ve used. I am a 50 year old wife, mother of four and a travel and sports enthusiast. I take an active role in my well-being and BIOSENSE™ helps me fine-tune my Keto diet. Since starting Keto, I have lost 30lbs and kept it off for several years. I am free from yo-yo dieting. My key to success on keto is tracking my ketone levels. With BIOSENSE™, I can track my levels without overpaying for expensive blood strips and meters. Plus, no more painful finger pricks! BIOSENSE™ is an amazing tool that I use daily to meet my keto goals. I highly recommend BIOSENSE™.

Without my BIOSENSE™, I would have no idea of whether I was on the right track or not. I understand there’s a blood test too. But to get accurate numbers you have to test yourself 3-5 times a day. I don’t want to prick my finger five times a day when a simple breath test will do the trick. I’m so glad I was turned onto my BIOSENSE™. I don’t think people should launch themselves into the Keto world without one. I just remembered a friend is on the diet and his birthday is coming up. You can probably guess what I’m getting him for his birthday!
