Works as toothpaste. Though, it's not intended to be it.

I've been using this as toothpaste and it has worked pretty good so far. But, it's very acidic, so it might be smart to completely wash it out afterwards. I have taken it dilluted too and it works as intended, the product is what it should be and the dispenser is convenient.

GSE - fantastic product

Posted by 5329944388108570760 on May 08, 2016

Waht can I say? GSE is an essential for me. Great for warding off colds and plenty of other things besides I took a bottle to India with me and washed my fruit and veg in a solution of boiled water and a few drops of GSE. No tummy bugs and I was there for a month

different result than expected/ happiness in his voice

Posted by 5182787146468592770 on Apr 22, 2016

My brother used an old bottle nutribiotic for his laryngitis which had citricidal in it. That took care of pretty bad case of laryngitis after a month. Then he had me order 2 bottles of the new formula & then another 2 bottles. So maybe he's gone through 3 bottles of this product. I'm not sure exactly how much he's been mixing in with his coffee & creamer every day. He told me 40 to 50 drops a day in his coffee. What I do know is that after using this for several months I noticed he wasn't so moody & he had happiness in his voice. As it has been said before, you need to take a higher dose for a longer period of time to see a difference. His brain appears to working better. My sister gets to see occasionally at his apartment. I only talk to him on the phone. She said he was less grumpy. Reality I didn't think it was necessary for him to take such a high dosage of GSE for such long period of after the laryngitis went away. He continued to take the GSE because he didn't want to get sick over winter. And most he definitely wasn't sick over winter. His choice to continue taking it has most definitely has improved his mood. What this exactly means I'm uncertain , just writing what I observe. I was surprised by the happiness in his voice.
