The product came really fast in the mail, and so far so good! I only take 6 grams a day (2 tsp) in a tall glass of juice on an empty stomach. Although I've heard stories of terrible constipation and it tasting like bleach, with my level of consumption and concentration, I don't taste anything and I've already started experiencing (it's been about 2 weeks) what I think is the healing of my leaky gut symptoms - More consistent bowel movements, and a lessening of food allergy rashes and breakouts. Even though I also take a probiotic with this product and eat foods that are rich in l-glutamine, I didn't start seeing the results I'm now experiencing until after adding the l-glutamine powder to my daily regiment - It's totally shot my positive results through the roof! I absolutely recommend this product to anyone who has been struggling with healing the lining of their gut.
