Ascorbic acid - that’s vitamin C. Does this mean that one can potentially expect odd/inaccurate readings after ingesting vit C containing substances?

Thanks for posting this.

I echo Terry4- I’m enjoying the chemistry talk on this thread.

Erm…

Have used both and could see no value in wearing both at the same time.

This is exactly why I LOVE this site and community. Thanks for the awesome info @Chris72

Yes Ascorbic acid is vitamin C. No one will be surprised after drinking orange juice that their CGM BG will be going up. But the fun test, is to take a supplement between meals, or when skipping a meal, and see what happens. It won’t be as much signal as Tylenol (acetaminophen), which can overload your sensor, but it will affect the baseline.

Hmm, another test I haven’t yet done with my son. Looking forward to seeing what happens.

mikep - you are welcome, chemistry is fun!

The Ambrosia Systems website has actual content now - https://www.ambrosiasys.com/
They have two versions, a disposable that sticks on top of the libre and a reusable that needs an armband to keep it in place.

This is GREAT news… I need to get the Loop people to make it possible to import from this reader. It would save me 3000 EUR per year if I could use Libre as CGM, instead of paying for G5, despite the accuracy issues.

Fyi, I have been in touch with the Ambrosia Systems - the maker of the BluCon transmitters and we have initiated the work on making BluCon readings as a blood sugar source in the Loop APS. Once this is in place the APS market will open up for most of European users, considering the fact that the Libre is being offered for free by the national health insurances in most EU countries, mine included. That’s a saving of 2500 USD per year there.
