My husband loved "Activase/Quadrase." Hopefully Fodmix will be as effective. After going through an elemination diet and reintroduction, careful choices and your enzymes have given him so much relief!

How do people not know about this! I have celiacs and can't drink milk of have dairy and I have been spending way too much money on "dairy free" items. I tried this the other day on normal half & half we had in the fridge. I gave it 48 hours to do it's thing and haven't had an issue at all. Man it's a game changer and is going to open up so many options for me now.

I am so pleased with Itoleran and the people that supply it!! It works perfectly for me. I have ordered the Lactose formula but the regular works so well-I will probably use one or the other at times. I am so pleased to be able to have it sent so promptly! Thank you for how well you run your company. I am so grateful. Ann Sand

I purchased the carbohydrate and sucrose enzymes. They really make a difference. A little more costly to maintain and didn't notice if there are larger quantities.

We are very happy to hear that our product make such a difference! The larges quantities that we offer are bottles of 108 capsules, when you apply for a subscription on these then you get a discount with every order. This might help you save some costs.

My order came quickly and so far I think I notice improvements in my digestion. Now just need to find something to increase my motility. Thank you

I am using 2 of the enzymes, one for starch such as potatoes and pastas, and another one for fruits. Both have been working well for me. I have used the starch on for 3 months and the fruit one for a month. Will continue to use both. I have found that two capsules work best for me but I can’t take them together as I get an upset stomach. I decide which I should take by what I am going to eat.

I have had stomach issues for many years. Lots of foods made my stomach swell up. After finding the digestive enzymes, I can get just about anything I like and no more stomach issues.

Calmed the burn!

I have used a different enzyme product, but intoleran has actually taken away the burn after eating tomatoes. The other product did not work as well.

I am still in the trial phase of the enzymes but so far they seem to help. I had sent a question to the dietician but never received an answer so that was disappointing

We are happy to hear that the enzymes seem to work so far. Unfortunately, we didn’t receive any email from you, therefore you didn’t receive an answer. Feel free to contact us again on info@intoleran.com

It works. I feel like a new person. Don’t forget to take it before you start cooking if you taste frequently.

Works Great & Love the Dispenser

I have histamine intolerance and use the Intoleran Mini version of DAO when I stray from my usual strict low-histamine diet. It works better than other types and brands I’ve tried. No side effects. Works quick (I usually take it just 5 minutes before eating). On top of that, I LOVE the dispenser it comes in.

Disabled veteran with severe IBS

I am a disabled veteran with severe IBS. After almost 20 years of suffering daily, I finally have peace and digestive stability thanks to intoleran. I have been working with a dietician while I navigate the low Fodmap diet and personalization stage. Doing the elimination diet was a game changer as it gave me brand new information about my intolerances. It turns out, I have an intolerance to almost every kind of Fodmap. Enter intoleran - a literal life saver and mental health super hero. Gone are the days of turning down dinner invitations and social gatherings for fear of a blow out. Now I can even go to restaurants again without needing a week to recover! Thank you for the work you do in this vital medical field. You have changed my life for the better and I couldn't be more grateful. I told my dietician at the VA all about this product and she was delighted to learn of it. Now even more vets will get the support they deserve.

Intoleran Quatrase has been a game changer! They’re a little pricey, but they work, so they’re worth it for that reason. I hope one day they’ll increase the amount of capsules!

Doctor recommend

They have highly doctor and nutritionist recommended enzyme supplements that are not 100% but its a lot closer than anyone else and the only real sucrase isomaltase on the market imo.

Helpful product, but expensive

I eat a plant predominant diet even though I struggle to digest FODMAPs in many foods. I’ve found the quatrase 10,000 to be helpful in allowing me to eat a variety of foods more comfortably. However, the product is too expensive for me to afford taking them with every meal (even buying the bulk bottle). There are people with more limited income than I have who would benefit, but simply can’t afford the products.
