I bought this off the internet about 1 and 1/2 to 2 years ago, and put in my drawer and forgot about it. Then I have had some health issues, GERD, which this year I suffered for over 4 years. Frequent visits to the doctor, at least it was discovered I have a hiatus hernia/oesophagitis. Man, it is brutal. This is after I insisted on having the camera put down into my chest to see what was wrong, I no longer had a life the burning searing pain in my chest across my back and shoulder blades, and up my arms. I could not do anything for 2 years, I hardly left the house.
I bought Joe Barton's book for acid reflux. Medicines did not work. I thought at age 66 I am done for.
Then I remembered this in my drawer, NutriO2, after my doctor told me that I am resistant to all medicines. On the 11th of July 2018, I came home and that night one hour after I had eaten just a tiny amount, I took my first 15 drops in pure water. Like it said on the bottle, I followed up the next day, 3 times a day. I woke up on Friday, the 13th of July 2018 with no pains, and have been brilliant ever since. I can't believe it; I will be buying more.
This is the truth.
Bottom Line: Yes, I would recommend this to a friend
