Cole slaw
Based on one time I have to say very poor. However, I tried it just before eating my nemesis, cole slaw. I’m not giving up on this product yet, but I am swearing off cabbage forever. I am sure I will have better results with bread and pasta.

Thank you!
I literally wouldn’t be able to eat any food with starch in it without Starchway. It has taken a shockingly difficult diagnosis and turned it into an inconvenience. Thank you!

Great CS and Life Changing Products
Customer service helped with all of my questions. The products have allowed me to eat again… and to live after doing it rather than suffer for hours and days. I may even finally be able to gain a (much needed) pound/kilo or two.

Quatrase is perfect for folks with multiple digestive issues.
Quatrase works very well for those with multiple food intolerances especially when being served foods where the full ingredient list is unavailable. Very easy to order online and shipping is quick.

I have interstitial cystitis (chronic
I have interstitial cystitis (chronic, inflammatory bladder condition) and foods high in histamines hurt my bladder. Intoleran is allowing me to eat moderate amounts of high histamine foods, which is wonderful. It also is accomplishing this without adding vitamin C to the DAO, which is very unusual and makes it possible for me to take DAO (people with IC are notoriously intolerant of vitamin C, as it is very acidic). The dispensing method which the little container has is cute, but I would much rather have a container that is NOT MADE OF PLASTIC. Cardboard would be just fine, cute dispenser or no.

Great product and great people.
It’s always nice to receive a sale price on a needed supplement. I personally believe that these formulation s of the DAO is stronger and has less fillers than US products. I have been a steady customer for several years now and have communicated with them on a number of occasions. They are supportive and knowledgeable. The US distributor has improved significantly. I don’t have a complaint.

Still waiting for order
The website is not payment friendly. I attempted multiple time so purchase an item weeks ago with my debit and credit card. None of my attempts were successful and I still don’t know why. My bank was informed of my attempt to make the purchase. The shipment takes entirely too long. I needed this item before I embarked on a trip, it will not arrive in time.

Too many capsules to be effective
I need to take many multiple capsules. The cost is excessively prohibitive. I don’t even get 3 weeks out of over $200 worth. The price needs to be 50% of what it is now or the capsules need to contain much more product.

Intoleran Starchway has helped me with sucrose intolerance when nothing else could , unless I was prepared to pay thousands of $’s every month. It’s not 100% but I’m about 80%better than before I discovered it. So glad to have found it!!

The order will arrive way beyond the garunteed time frame. I am leaving on a trip and depended on this garuntee. I plan to return the product and go with another company since not meeting the first promise they have made to me is not a good sign that a company can be trusted, in my opinion.

Highest quality, enzymatic quantity, and new life for daughter
Very crisp, clean, and easy to browse & learn before ordering. These enzymes are THE ONLY ONES that work for my daughter; no other brand besides Intoleran actually has enough of the particular enzymes she needs. Thank you for making your products, as it’s allowed my daughter to participate in eating and not feel gravely ill.
