I really appreciate the deep research backed behind this product (I also have his book. Still need to read). I've been a consistent customer for WELL over a year now but I may have to stop. Things are getting so expensive that I'm having to find a more affordable product. Also, there are SO MANY 'Other Ingredients' that I didn't realize until recently (not sure how I missed this). There's probably a reason for that. I don't like the citric acid, natural flavors, stevia AND monk fruit (rather than just one), ,,, I don't know. I've lost trust with the American food, preservative, and supplementation systems. I've struggled with health issues and wonder how much of it has to do with these 'fillers' that people say are 'reasonably safe'.
