DAO – great product !
Great products. I use the DAO, discovered it on the Netherlands while traveling. It works super well to keep histamine reactions away! Really like the little dispensary box and small size of tablets.

The various amounts of pills that can be purchased is nice. The metal containers are wonderful for keeping pills in my purse. The enzyme work well for me- I’ve been able to eat foods I haven’t eaten in a decade! I’m fructose intolerant.

The product works as expected. Before knowing your product, I had to buy lactose free milk which was also often fat reduced. Now I have the freedom to choose any milk I like.

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.

Quality Declining
I have noticed in my last two orders that the once a day lactose capsules are not consistent. Some of the capsules are no longer full. So I am paying for doses with less of the product? I thought I finally found an honest reputable company but it seems you are doing what every other business is doing. Giving us less and taking our $$. I have also needed extra dose at times of otc lactose. So this product isn’t working like it used to. I will not be recommending it to others like I used to. Sad.

My package never came
My package never came. I emailed Intoleran and the person who responded said they’d follow up about my package but it still never arrived. I attached a picture below with screenshots of all the excuses they gave for not delivering it. I have used Intoleran off and on for years and I never cared that it was pricey because the product is excellent. But I can’t believe you would work with a shipping company that treats your loyal customers this way. I requested a refund and I will be purchasing Fodzyme moving forward.

Starchway actually works.
I started using Starchway about a week ago. I still have gas but I do not feel bloated like I did before when I would eat anything. I have had issues with potatoes, pastas, rice and fruits.
I found relief with the first time I took it. It was a little confusing at first. The box said to take one capsule before eating, but the web site said to start with 3 capsules. The 3 really worked well but gave me a mild stomach ache. Then I tried 1 capsule but didn’t get as much relief so I settled on 2 capsules every time I eat. That seems to work the best for me. No bloating and no stomach ache.
By far the best ting I have found so far.

Life saver, it has been a game changer.
I had an illness and started drinking black tea instead of coffee. After I felt better I made me a drink and it made me sick, face flush, blood pressure high, swelling eyes. I ended up with high histamine. I stopped drinking tea and the damage was already done. The DOA has been the only thing that has put me back to normal. I highly recommend it.
