I have not gotten sick in almost a year because of this. I have recommended it to several friends. I do have celiac and I can not have many other foods. When I am in a situation where other people are preparing food for me I take this just in case there is cross contamination or they don’t understand the severity. I also take it as soon as I start to feel bad. This keeps me from being sick all night.

Well I think it’s perfect the way it is but if I was to say other than Lowering the price cuz I have to order it every month and also making it longer than 4 hours would be great but if not I think intoleran is great because it allows me to be able to eat again to eat some of the things that was taken away from me with this histamine intolerance and I thank God for you people you are doing a great job because this type of product is nowhere else that I found and I looked

It took 10 days to receive the product
It took 10 days to receive the product. Unfortunately, Intoleran uses DHL which is notorious for SLOW delivery to the western states. It took the Pony Express 10 days on horseback to deliver mail to the western states in 1860/1861 and DHL still hasn’t figured out how to do it any faster. Horrible delivery service.

If you have CSID, other prescriptions like Sucrotase do not work for you, try Intoleran. Also, get a nutritionist. Help yourself.
I have CSID. Bloat is in me and with me continually.
I have modified my diet according to its needs to digest food , used a prescription that caused side effects unmentionable.
Try Intoleran and get a nutritionist who is familiar with your diagnosis.
I found mine in Oklahoma!

The Quatrase Forte and Fibractase Forte work great! I am able to eat many more foods since discovering them!
I used to have to order from the Netherlands and it took 3 – 4 weeks for them to arrive. Love that there are now distributors in the US.
I did receive a promotional email that showed bottles with 108 capsules were available for purchase. Unfortunately, it turns out that is only in other countries and not the US. I purchase 4 packs of each product every time I shop. I would be nice to have the bigger bottles. It would also be nice if those 2 products were on the subscription option as well.

⭐️⭐️⭐️⭐️⭐️+
My 16 yr old daughter became lactose intolerant out of nowhere. She was having pretty severe reaction from burping, gas, nausea, vomitting, and stomach aches. I found Intoleran online and thought we’d give it a shot. And after the first week of taking it she has been able to have all the dairy she wants. We will continue to buy it. I do wish they would offer a subscription for it though. Would make it alot easier getting it every month.

A stellar company.
I have had a great experience with your company. When the payment method for my subscription failed, I was notified immediately, and was able to fix the problem without a lag in my medication delivery.
My only issue is that, if a holiday occurs between the processing and delivery of my medication, I sometimes have to go several days without it. This negatively impacts the cumulative benefit. As it is, I am lucky if I have 1 pill left, by the time the next prescription arrives. Thank you. Denise Leuschel

changed the way I eat food
I absolutely love what Intolerant offers. I have Sucrate deficiency. The medicine is available but extremely expensive even through the insurance, but this little pill bridges the gap very effectively, and it’s lovely that you can travel with it. I also love the fiberactase pill. It works great to with Indian food especially dal and beans . It is truly changed the way I eat and enjoy food. Thank you thank you

This is my second order
This is my second order. I was nervous the first time buying.. but was glad to find it works great 100%. I eaten food I have not had in over a year. I had to stop eating so many foods I love because of this histamine. But thanks to these pills in eating again even though it’s a small window that makes it safe for me I’ll gladly take it. Thank you all so much. I will show these to my doctor on my next visit. What can be done to improve our make better.. I would say give us a longer time if possible like more than 3 to 4 hours. Other than that this is a miracle product. Do you make TV commercials on this. This something everyone needs to know about. Than you

What is lactose?
Lactose is a specific type of sugar found in milk and other dairy products. The enzyme lactase breaks down lactose into glucose and galactose, allowing the intestinal wall to absorb it. If there is insufficient lactase enzyme present, lactose cannot be broken down and absorbed in the small intestine.
Intoleran products contain the digestive enzyme lactase, which aids in the digestion of lactose, reducing the risk of associated complaints.
