I woke one day about 6 months ago with almost sudden Rosacea and it coincided with my gut health taking a nose dive. Both were getting worse almost daily and in that time I tried nearly everything. Change of diet, digestive enzyme, different skin care, nothing worked. Was basically living off celery and bone broth but still not really getting better. After having done so much research on the gut, I came to the conclusion that it could very well be “leaky gut” that I was dealing with, and that the Rosacea was the result of it. So “Glutamine” was suggested to repair the gut and I found this stuff. At first air was taking about 10 grams a day but soon boosted that to about 15-20 grams a day. I take it on and won't stomach and don't eat for about an he after consuming it with powder. It's working. Slowly my gut is healing and my skin is clearing up. Borderline miraculous really. I credit about 90% of the recovery to this product. It's been about 4 weeks now and my gut and skin are the best they've been in over 6 mo. This stuff works. Hope this helps someone that is dealing with the same type of problems. Buy it. 15-20 grams a day on empty stomach
