Update by user Mar 11, 2021 Change to auto delivery schedule. No problems. Original review posted by user Mar 11, 2021 I had no problems with my change in frequency. Very helpful on phone. Love the product. It works well for me. I have had 3 colon blockages with hospitalization in the last 10 years. I haven't had any more since taking this product. Brought all my bloodwork levels into normal range and has stayed there for 2 years now. They have been abnormal for iron, CRP, cholesterol etc for as long as I can remember. User's recommendation: Try the product.
