Insulin SOS: A Mysterious Case of High Blood Sugars

Featured Podcast Episode
November 14, 2023

I have to share a story with you about a mysterious high blood sugar case that one of our coaching clients experienced recently.

For two weeks, he couldn't figure out why he was running higher than usual- we're talking mid 200's and 300's.

He went through his usual list of reasons:

  • food
  • insulin sensitivity
  • stress
  • sleep
  • hydration...

But none of those factors seemed to be the culprit.

Finally, on one of our coaching sessions, I asked him: "Do you think your insulin has gone bad?"

Turns out... that's exactly what it was.

If you're anything like me, and this particular client, you might not always be thinking about keeping your insulin at a safe temperature.

As a friendly reminder…

In the refrigerator, insulin should be stored at:

36°F to 46°F/ 2–8°C

And outside of the fridge it can withstand temperatures between:


This means if you live in or travel to warmer climates (or very cold climate) then your insulin is at risk for spoiling.

We all know that this is stuff is our liquid gold - which is why I recently bought the Voyager Cooler from the brand 4AllFamily.

If you don't know them, 4AllFamily creates products that help people protect their insulin and they have more than 200,000 customers worldwide in USA, Canada, Australia, India, and soon Europe. The majority of their staff also lives with T1D which are companies I always love to support so if you don't yet have one of their insulin protectors, check out their products - available on Amazon and on the 4allfamily website.
