Delay in receiving it
Ordered 10 days ago, it has still not arrived. In the mean time I get multiple emails asking me what I think. Please check the delivery status first. I hope the product is good and worth this unbelievably long wait.

Maybe reduce the packaging size. Last time for one small box I received an a3 i guess pack. Tiny but still huge for the small box. The rest is well done, well organize, reliable and efficient.

It works
After endless trials with different supplements (I have FODMAPs intolerance + histamine intolerance), I have finally found enzymes that work! I still have to be carefull with food especially amount-wise but I can at last eat things that were forbidden before (chocolate, sauerkraut, ice-cream, different fruits…). Also, the delivery was fast and reliable.

The product itself is great
The product itself is great. Sadly as it has to be shipped from Europe to the UK the tracking information is less than reliable. It also means that it is expensive – it works out at £1 per tablet

Best Enzymes in the market
I’ve been using Intoleran for a few years by now, and I simply can’t imagine my life without it. I use it every time I eat out or have something forbidden at home, and thanks to Intoleran I’m usually able to not regret it the next day.

Great products and fast delivery! since finding out I have a mild lactose intolerance issue these products have helped me tremendously by still being able to enjoy my food without any discomfort or having to worry. When in doubt, just take a tablet and no issues anymore whatsoever.

Excellent products.
Excellent products and brilliant customer service.
I would give maximum star rating but cannot simply because of the substandard courier service that I experience each time.
When the products arrive in the UK they are then delayed for unacceptable lengths of time whilst Royal Mail handle the delivery at this end.
Intoleran dispatch initially via FedEx promptly so why can you not provide FedEx door to door which would solve the frustrating delays caused by Royal Mail every single time?
I’d happily pay extra for a door to door FedEx service.
Great company but rating sadly let down by the delivery service in UK.
I’ve consistently been able to get products from the US, Australia and China much faster.

Great product and excellent customer service
Following the suggestion of my nutritionist for IBS, I ordered
Quatrase, but due to an issue with the delivery, my product never arrived. Since I had urgency to receive it for an upcoming holiday, I contacted the customer support, which promptly and very kindly provided efficient solutions.
Now that I also had the chance to try this product, I can complete my review confirming that it works: I ate any kind of food without having my usual bloating problem I used to experience after every meal. So, thank you Intoleran and special thanks to Annabelle!

Freedom to eat without worry
I can eat an occasional processed meal without worrying about onion, garlic, etc. I just take 2 or 3 Fibractase. For Christmas I will take Quadractase and enjoy my food.

However we never received a single flask which did not leak somewhere near the lid
That makes it hard to get the dosage right since you get additional drops from the leak

Wonderful Company to deal with!
Wonderful Company to deal with. Excellent responses and response time. Product is superior and extremely convenient to use, also, very cost effective. My wife and I require the Lactase enzyme and the drops are what we purchase. Using this product HAS been very BENEFICIAL and is extremely simple to incorporate into milk and milk products. Very highly recommended. It has been a blessing to use in our household to fulfill all our needs regarding our “lactose intolerance” condition.
