Best Brand of Activated Charcoal?

Looking to add a binder to my current protocol as I am without one. I’d like to try charcoal, but wanted to get a feel for which brand is the best/highest quality. Which ones do y’all use?

WalkingbyFaith, how often do you take the activated charcoal and how much? I'm just starting to try introducing it into my protocol, don't know much in regards to how to implement it. I know you have to take it away from food and other medicines.
