Gluten Free & Fructose Intolerant Athletes

I am an undiagnosed celiac along with sevre issues with fructose. I am starting to run & I would like to run longer distances, but I cannot use your typical supplements & endurance items as they contain sugar. The only sugar i can tolerate is dextrose which is pure glucose, I even stay away from most fruits & vegetables because of the ill effects of any fructose on my body. For most people the sports drinks give you energy of sorts, but for me the sugar causes extreme fatigue & exhaustion. I am wondering if anyone else has delt with this & can provide me with some suggestions. I have tried mixing small amounts of dextrose with water & it seems to help, but I'm not sure if that will work for longer distances.

I can't be the only celiac with fructose intolerance!

You definitely are not the only one. I'm totally off fodmaps while on an elimination diet, and it's helped so much. I am no sort of athlete, but I also am realising that I have some major problems with sugar. It's harder to give up than gluten, and that's saying something.

I have heard that a good basic electrolyte solution is a combination of sugar and salt in water, can't remember the amounts. You would obviously use dextrose. Could you have a look at the nutritional information on a sports drink and then work backwards to see what you should be having? You might be able to find safe supplements that you could add in to make up your own version. Can you make a safe energy bar to take and then drink water?

Otherwise, you could ask the question of the fructose malabsorption yahoo group. I've been telling everyone about it recently, but it is a very good resource!

By any chance did you come up with something to drink? I'm not sure if I have fructose intolerance but I know I cannot tolerate sugar when I exercise. I'm at a loss on what to take with me on longer bike rides or harder workouts.

      Desperately need a vitamin D supplement. I've reacted to most brands I've tried.

      Thanks @Scott Adams. Do you know if Kirkland Signature supplements share facility and production lines with other products containing gluten? I'm worried that I'll react to this brand just like I did with other gluten-free labelled supplement brands.

      Unexpected gluten exposure risk from cultivated mushrooms

      This is a really common area of confusion. Most natural cheeses (cheddar, Swiss, mozzarella, Parmesan, brie, camembert, and most blue cheeses) are inherently gluten-free, and you’re right that the molds used today are typically grown on gluten-free media. The bigger risks tend to come from processed cheeses: shredded cheese (anti-caking agents), cheese s...

      Kirkland brand (at Costco) is gluten-free and is 2,000 IU.

      Unexpected gluten exposure risk from cultivated mushrooms

      Thanks a lot for your response! Can you maybe specify which kind of cheeses I should be cautious about? Camembert/Brie and blue cheeses (the molds of which are nowadays mostly grown on gluten-free media, though, so I've read, right?) or other ones as well? Also, I was under the impression that yeast is generally gluten-free if not declared otherwise...

      This is a really common area of confusion. Most natural cheeses (cheddar, Swiss, mozzarella, Parmesan, brie, camembert, and most blue cheeses) are inherently gluten-free, and you’re right that the molds used today are typically grown on gluten-free media. The bigger risks tend to come from processed cheeses: shredded cheese (anti-caking agents), cheese spreads, beer-washed rinds, smoke-flavored cheeses, and anything with added seasonings or “natural flavors,” where cross-contact can happen. As for yeast, you’re also correct — yeast itself is gluten-free. The issue is the source: brewer’s yeast and yeast extracts can be derived from barley unless labeled gluten-free, while baker’s yeast is generally safe. When in doubt, sticking with whole, unprocessed cheeses and products specifically labeled gluten-free is the safest approach, especially if you’re highly sensitive.
