Important thing is not to get liver in capsules (dose goes WAY down), and to always take some source of fat with the de-fatted liver tabs to increase utilization.
The Beverly ones are working for me for now, so I'll stick with them. As I consider them part of my "food" bill, the price difference isn't a dealbreaker for me.
I also use 2 Tbsp of liver powder from Leviticus11.com as a part of my morning "swamp drink". I do no other protein powders.
