This product has been developed for diabetics (and is therefore prescription-free) and has been on the open market for a few months. It can be bought for 65.30 on freestylelibre.ch - a website of the company Abbott (the producer and distributor of this sensor) and then used with a free app (also from Abbott). You can also pay significantly more with solutions like Levels, NutriSense or SuperSapiens. Levels and NutriSense are focused on nutrition and lifestyle, SuperSapiens on glucose optimisation for athletes. But one might ask what good is permanent glucose monitoring for a person without a serious metabolic pathology? A few weeks are more than enough to learn which foods are problematic and which behaviour is best in which situations. And a sensor can be ordered for special occasions (prolonged fasting, targeted training, etc.). Otherwise, Levels is officially still in beta and is working with scientists (including Harvard genetics professor and anti-ageing expert David Sinclair) - so perhaps we'll see its members involved in some large-scale studies, which would be interesting. Beyond that, Abbott is already working on a next generation of permanent 'biowearable' sensors, this time designed directly for the general public, so without medical ambitions, but capable of monitoring glucose, ketones, lactate and alcohol. This sector is booming and I hope that Galaxus intends to follow the movement closely?
