Sorry for my delay in responding just haven't been keeping up. As far as how I came up with the protocol. I have a Master of Nutrition degree and I spent a lot of time looking at the research. Your taking the Knudson's is fine but I have read studies that the Montmorency type of cherry from Michigan is the most beneficial based on nutrient content. I use Obstbaum Orchards concentrate which is much cheaper and can be bought online. It also has a longer shelf life and I just use it full strength in smoothies or it can be reconstituted back into juice by adding water. I know from my experience when my uric acid levels were 14-16 I had many more gout episodes. Touch wood I am now 6-7 and can't remember my last episode. So I do see a correlation with me as far as uric acid levels. All in all the protocol helped to start but when I found out the CKD and started to limit my proteins, especially from animal sources which I still eat 3-4 times a week, and reduced my sodium things really improved. Also my eGFR and creatinine levels have improved as well.
Hope that helps.
