Great products and fast delivery
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.

Works great
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.

Very effective in minimising indigestion
I used the sample pills for the first time during a trip abroad and they were super effective in minimising symptoms I normally would feel when ingesting carbs (in this case, pastries and bread).

Bad experience.
I ordered a product on December 8th and yesterday I finally received an email saying that the order had been delivered. It was delivered but not to me!
I exchanged a few emails with Intoleran and when I showed my displeasure, they stopped responding! Right now I’m without what I ordered and without the money I paid! Honestly, I still hope the situation gets resolved!

My experience so far
Response via e-mail was very quick and accurate. Package arrived in a good shape. I tried smaller package of Starchway. I liked that it had long expiration date. Capsules are small, easy to swallow or open. It seems to be helping me with my starch and sugar intolerance a little, but I am still testing it and figuring out the right dosage. Hopefully it will be helpful (and in that case I will be ordering more:)).

These enzymes are lifesavers for me
These enzymes are lifesavers for me. I can finally eat a more varied diet despite my very low tolerance for FODMAPS. My only request would be that you try to develop enzymes for polyols (mannitol, sorbitol) if possible, because I really want to be able to eat more fruits. Thank you for all you’ve done!
