About Intoleran

About Intoleran – Digestive Experts

Intoleran is a Dutch company focused on developing a wide range of dietary supplements that support digestion. Our mission is to help everyone to enjoy food again!

The story began in 2008 with founder Remko Hiemstra. Remko, who is lactose intolerant himself, saw that there was still much to be gained in the field of lactose intolerance. Driven by this, he started developing a supplement that aids in the digestion of lactose in food. In the years that followed, a broad range of dietary supplements was developed to support people with various digestive issues.

As of 2024, we sell our wide assortment of successful and highly appreciated products worldwide. A growing group of consumers, in Europe, the United States, Australia, and beyond, benefits from digestive support, allowing them to enjoy their favorite foods!

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.

Great products, feel more included with friends.
After a long journey I found out that my issues were with FODMAP’s. Intoleran team is very knowledgeable, answering all my complex questions about what products to take and how much. I assume the person answering my emails was involved in making or studying there products because my questions were very in depth and thoroughly answered. If you have an issue tolerating Fructans, Fructose, or Lactose give this company a try. I ate my worst trigger foods while on a low FODMAP diet and showed no reaction during or days later. I’m glad I took a shot by purchasing the sample packs.

Intoleran has been a life changer
Intoleran has been a life changer. I can eat foods again I thought I would have to avoid forever. I can enjoy date nights and cooking again. I love the little metal packaging but my curbside recycle doesn’t pick up metal other than cans, so I’m currently trying to figure out how to recycle the packaging. Wish I could send them back for refills.

Excellent Pills, Difficult Payment
These pills are a life changer. I really truly need and appreciate them. That said, I cannot buy them with HSA funds, which is a real frustration, since they are so expensive. The payment goes through the Netherlands, so the HSA cards will not work. It’s a lot of money to pay out of pocket for as often as I need the pills.
