Delivery was prompt. I've tried several brands of chlorella and this seemed to be the richest so far (very dark green and the taste was very good) I did a lot of research on the different types of methods for cracking the cell walls for better nutritional absorbtion and for the price I think this is the best you can find without going with the more exclusive brands that use ultrasound instead of high pressure spraying. Its also pretty hard to locate organic as well. So far very satisfied with the increase in energy levels. Several people have commented on the adverse effects of taking chlorella but they are mostly likely experiencing the symptomes of the mobilization of the remaining parasite toxins and heavy metals in their bodies. It will be more fruitful and less problematic when used in combination with a standard detox program with enzyme supplementation.
