I have that same bottle and am still missing that.

Take a look at the photo of the bottle here:
https://www.amazon.ca/Vitafiber-Basic-Syrup-1-2-kg/dp/B00TE3ELJ0/ref=sr_1_1?ie=UTF8&qid=1485110418&sr=8-1&keywords=vitafiber

This is the same product label on the bottle I have.

My bottle of Vitafiber does not say anything about needing refrigeration.

Note - the Vitafiber bottle does say "keep refrigerated"

I haven't found a good replacement, unfortunately. But, I think using nut butters and stevia might be good way to get a soft protein bar. Cream cheese may also work. I've got some experimenting to do. I'm not using the IMO syrups anymore due to blood sugar impact. I had a great texture making fudge from LC Foods condensed milk powder so that may be another option. Sorry, haven't figured it out yet.

I'm just wondering what you are using now instead of the VitaFiber? I was so excited about trying your recipe!

Julie - I looked into this some more and found that a lot of diabetics have blood sugar spikes when consuming VitaFiber because not all of the high glycemic carbs are removed during the processing. I won't be using this product anymore or recommending it. Apparently, it was too good to be true. Thank you for letting me know!

Unfortunately, it appears as if things calling themselves "VitaFiber" is simply malrodextrin being re-branded and sold with HIGHLY inflated prices. 🙁

Just thought you'd like to know, because maltodextrin can be had very cheaply.

Super simple.

It's a tasty snack that's so quick and easy to make, you might get hooked.
