A game changer
I have been buying this for 2 years now and his had greatly improved my digestive health from gastritis and food poisoning. I have been able to use this instead of famotidine and omeprazole. There is no funny smell or taste either. This product is a life saver for helping with inflammation and assisted me with losing weight during my flare up.

Stuff works
Stuff is amazing. It made a difference after first day. I use in conjunction with their Colostrum product and am feeling much better daily. Takes a couple months for most to receive any benefits. The bad: after two months I started getting major heartburn feeling going up my throat. It wasn’t noted originally as GLR being the cause but once I stopped taking it, the heart burn went away. Product has a high amount of homeopathic herbs and some of which causes minor side affects. It’s powerful stuff but if this happens then it’s a good sign. It means to stop taking it and because your gut lining isn’t the problem. It took two months for me and may take more or less or no time at all depending on your body reacting to it.

Early review
So far so good. I have been taking for a few days so probably will need to update again after extended use. Pills are easy to take, there has been no bad taste and hasn’t upset my stomach.

Made my nausea worse :-(
I bought this months ago and quit after a few capsules, then forgot about it. Then recently I found the bottle and couldn't remember why I stopped taking them before. I reread the reviews and was hopeful these could help my leaky gut and whatever else is going on. Five days into taking them again, I remembered why I didn't like them before: worsening symptoms. :-( I REALLY wanted this to work because the ingredients are amazing! Sadly, at least for now, I cannot take these. So disappointed!
