Real Testimonials

Hear From Our Customers

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 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. 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!
