Gives me hope

I've struggled with chronic gastritis for three years and have been relying on the maximum dose of PPIs you can take. Even with those, I was still in constant pain.

A month ago, I completely stopped PPIs and began Intestinal Fortitude's "Reduce, Repair, Rebuild" bundle. I didn't have much hope that it would work, but I was wrong. In tandem with the supplements, I went to a strict, non-inflammatory diet (mostly fresh vegetable juice multiple times throughout the day day and sweet potatoes + baked fish + rice in the evenings).

The pain has mostly stopped. And if I feel it coming on, I take additional GRL-6 supplements. It's a game-changer and I finally have some hope that round after round of specialists couldn't give me. So grateful. I don't think the supplements are necessarily a cure-all. In my case, I had to cut out bad habits to let the supplements do their work. Either way, I am incredibly grateful.

so far so good

So far these supplements seem to be at least making my symptoms much milder
then before I was taking them.

Surprised

I am only 12 hours out from taking my first dose. This morning to my surprise, I could drink my morning coffee without the pain/cramping and I did not have to rush to the bathroom. So far, so good. I love the feeling of relief! I will start the AI-5 Inflammatory supplements today too. Happy healing everyone! 👍🏻

Grateful for this company

I have an imbalance in my microbiome, and for the last 6 months acid reflux in my throat, also. Excessive acid in my digestive tract was feeding Hydrogen/Methanogens and making digestive issues worse.
Proton Pump Inhibitors we’re not fixing the problem.
I started with GLR-6 which was a tremendous help.
Next, I added AI-5 and L-glutamine. They also helped.
I am still tapering off the PPIs. Hope to use more of the products as I improve.
Wonderful company. Grateful for the help.

Not for me

I had a friend recommend Intestinal Fortitude as it worked well for them. Unfortunately, it did not work for me. There must be aome ingredient that does not agree with my GI system.
