Sometimes the product is excellent and sometimes it doesn’t work at all. Are there quality control issues where some batches are not effective?

I felt nauseous the next day. I’ve only used it once. I’ll try one more time to be sure that it wasn’t something else. It did help with the congestion and other symptoms I get from histamines.

The product was very good and effective. However, for the second time I had a delivery problem. One of your carriers (OnTrack) contacted me on two different orders that they could not deliver due to incomplete address. I tried to contact them but was unable to do so. In any event, on both occasions, the packages were delivered about a week late with no further address information from me. Further, upon receipt of both orders I noticed that the delivery address indicated on the packages was perfect. Suggest you review these situations with OnTrac.

I am so pleased with Itoleran and the people that supply it!! It works perfectly for me. I have ordered the Lactose formula but the regular works so well-I will probably use one or the other at times. I am so pleased to be able to have it sent so promptly! Thank you for how well you run your company. I am so grateful. Ann Sand

The Intoleran is helping me with my issues with lactose intolerance.
I’m still a little afraid to eat or drink dairy products, but so far, so good.
I’ve talked to several of my friends about Intoleran.
One of my friends has tried it and says that it works well for her.
So, I order for her too😊

Works Great & Love the Dispenser
I have histamine intolerance and use the Intoleran Mini version of DAO when I stray from my usual strict low-histamine diet. It works better than other types and brands I’ve tried. No side effects. Works quick (I usually take it just 5 minutes before eating). On top of that, I LOVE the dispenser it comes in.

Helpful product, but expensive
I eat a plant predominant diet even though I struggle to digest FODMAPs in many foods. I’ve found the quatrase 10,000 to be helpful in allowing me to eat a variety of foods more comfortably. However, the product is too expensive for me to afford taking them with every meal (even buying the bulk bottle). There are people with more limited income than I have who would benefit, but simply can’t afford the products.
