iHerb Customer Reviews
Comment by health consultant
This is a experience of a health consultant. "I have been seeking to clarify what the difference is in tastes, also. I am a health consultant and have recommended the original GSE to my clients for more than a decade. A client came to me with the new labeled bottle, saying it tasted different. I finally called Nutribiotic (the manufacturer). I was told that the manufacturer of Citricidal did not register its product with the FDA, so Nutribiotic could not sell GSE for internal use if it contained Citricidal. Therefore, it now uses other suppliers for its grapefruits. They say that's why it tasted different. They say they can't say that the grapefruits are organic because they make up less than 75% of the whole. I don't believe that is correct. I believe that they could say, in the tiny ingredient list, "organic grapefruit seed extract." What bothers me is the fact that the label still says "Original." It is not the same. Also, I am very concerned to hear that it does not function as well as previous batches. Citricidal used a proprietary process to make grapefruit seed extract so effective at killing the bad stuff without harming the good. If Nutribiotic is now making its own formula, it is unlikely that it is using, or knows, the proper method used in Citricidal. I used Citricidal years before the branded "GSE" came out. It saved my life by finally allowing my gut to return to balance. The old formula saved a family member from getting peritonitis when his appendix burst. This obvious bait and switch by Nutribiotic is very disturbing." As for personal experience - yes, the taste has changed, now it is bitterness. But it seemed heleped anyway. Judge upon yourself.

I am very happy with this brand of GSE, I was unable to find the one I wanted in my local area so I decided to purchase from iHerb. The price was very reasonable and shipping was extremely fast. I will definitely be ordering from iHerb again in the future and will be recommending them to others.
