Why Choose Intestinal Fortitude?

Intestinal Fortitude was founded in 2018 as a way to help manage my illness without spending a lifetime on prescription medications. Through hundreds of hours of research and testing, we developed a blend of herbal ingredients that brings me relief and allows me to live mostly symptom-free. I really hope they will do the same thing for you!

I personally take each and every one of our products every day, so it's very important to me that the quality remains high, while the price remains reasonable. We don't cut corners, we don't put cost-cutting measures above the efficacy of the product, and we never lose sight of why we started this project. We make products for ourselves because ultimately we suffer from the samethings that our customers do.

I’ve been looking for something to help with my diarrhea issues for a little over 4 years now. I came across this GLR-6 on here a short while ago & after reading the reviews I decided to give it a try. It’s just Amazing how much of a difference I’ve already seen taking this for 3 weeks, I will be ordering more soon.

I give this product all the stars because so much going to the doctor and many studies never gave me any diagnosis, but because of the discomfort I felt, I started taking this product that magically removed my discomfort, I feel better and I only have two weeks of taking it thanks to these pills I feel much better.

Every bit as good as expensive brands.
I was looking for an alternative to armra because it’s a fad brand taking advantage of a TikTok trend. Colostrum has been around since mothers were invented people. Just look for natural ingredients and you’ll still see the benefits and potential savings.

A great addition to my other Intestinal Fortitude products.This product is great. I really appreciate that it comes from New Zealand, as I know their daily products are much cleaner than ours. My stomach has definitely felt better since I started taking it. I take two every morning with a little water. Easy addition to my supplement routine.
