“I’ve had my COR One for about 6 months and it’s been such a useful health tool! The fact that i can measure a clinically validated inflammation marker at home is great, but the best part is being able to tag readings with what I ate or did on that particular day and seeing what impact that has - so much better than blindly guessing what works for me and what doesn’t.”
“The COR ONE completely changed the way i think about inflammation. But MUCH more importantly, It has changed the way i respond to it by providing reliable, near-real-time feedback to dietary and lifestyle choices. This is literally a ‘game changer’ My deepest gratitude to Bob and everyone at COR health, Inc.”
