We Conducted a Study on Probiotics and Heat

Lately, our customer service hotline has been ringing off the hook with questions about how Jetson probiotics hold up in high temperatures. Okay fine, we don’t technically have a hotline but that sounds better than “we’ve been getting a lot of emails” doesn’t it?  

Does heat affect probiotics?

We understand why it can be concerning that your probiotics (which are full of alive strains) may be sitting on your porch on 100 degree summer days from time to time. Especially considering that you’ve probably seen refrigerators stocked full of probiotics at Whole Foods and made a mental note that “all probiotics have to be refrigerated.” 

We’re trying to make gut health as convenient as possible, which is why all of our Jetson formulations can be stored anywhere below 77 degrees celsius (no fridge necessary) thanks to our proprietary capsule. But for those of you in hot spots (hey, Arizona!) we know you’re probably wondering if all probiotics die in heat… because 77 degrees sounds like a chilly winter evening and not a summer afternoon, doesn’t it? 

There’s no such thing as heat resistant probiotics, but...

To answer your questions, we did what we do best – conducted a study. We got together with QLabs, the leading Microbiology & Chemistry Product Analysis company, to ensure that our Fit formulation could survive the rigors of summer testing with no loss of potency or efficacy.

Our methodology was simple: put a bottle of Fit in a specially designed chamber for 10 days,  and crank up the heat to over 100 degrees fahrenheit with a relative humidity of 65% (in other words, we made it really, really hot). Each day, researchers would take out a pill and test it to ensure the bacteria were intact and thriving. 

Surprise! The results were just as we thought. Even after 10 days of non-stop 100 degree, sticky heat, our probiotics meet the amount of CFUs on the label – meaning you get all the bacteria we intended. 

 How? Well… we have two things going for us. 

  1. Our proprietary capsule design acts as a protective shield for bacteria, so that harsh environments, like heat and stomach acid, don’t come in the way of your gut health. 
  2. We include something called “bacterial overages” in our product. This means that although our bottles display CFUs on the label, we’re actually stuffing them with more than what’s listed. This way, even in the instance of a freak accident (like multiple weeks in 100 degree weather) you’re still getting what we promised you. It’s called “covering all your bases.”

You can give the actual study a read below, but when it comes to Jetson probiotics and heat – don’t sweat it.
