"If you have IBS, have to avoid FODMAPs and or have fructose malabsorption, glucose isomerase (Fructaid) may help. Doctors really don't have an accurate way to diagnose any of this stuff, but if you have extreme gastric distress after eating FODMAPs or fructose you probably have some of these problems.

There are enzymes that let me eat most of the FODMAPs (Fodzyme works best for me), but Fructans, one of the most common FODMAPs are broken down into fructose. Turns out I have fructose malabsorption, so the FODMAP enzymes only get 1/2 the job done.

So fructans break down into fructose and now I need another enzyme to break down the fructose. There are several brands of glucose/xylose isomerases on the market designed to break down fructose. If they work for you, then welcome to sweet, sweet sugar heaven.

For me, FODMAPs and fructose cause urgent, painful, explosive diarrhea. By first using Fodzyme to handle the FODMAPs and then Fructaid and other glucose/xylose isomerases to handle the resulting fructose I can freely eat garlic, onions and a tiny, tiny bit of low-frutose fruit (5 strawberries) with no gastric pain. This is with a double dose and taking the pills out of the capsules to get faster digestion. Any more fructose and things get ugly fast.

My dream of eating an entire pint of Haagen Dazs with suffering extreme gut pain is still out of reach. So I rate this 3-stars for effectiveness because of my cursed genetics. For some people, this is going to work great and they will be allowed through the gates of sugar heaven.

If you know that you have problems with FODMAPs, but FODMAP restriction isn't working well, you may also have fructose malabsorption. For me, Fructaid is enough to finish the digestive process left unfinished by FODMAP enzymes. But it's not enough to enjoy sugar in any meaningful amount."

"I have fodmap intolerance and this works like magic! No bloating, gas or icky poops. Totally worthy the money!"

"This is so helpful for my daughter who is fructose intolerant."
