I was recommended D-Ribose as a helpful supplement for Fybromyalgia. This was the best value quantity & strength applicable for that &, in combination with some others, I do feel there is some improvement. Not a massive difference but enough that I'll continue to take.
This product is amazingly helpful in maintaining health and energy. After using it for about a year, I had my annual checkup and along with my blood pressure being lower and heart in excellent shape, my blood oxygen level was at 100%.
This is all very good news to both me and my doctor.
Also, my order was filled and delivered in a very timely manner.
