I have purchased a few different brands of activated charcoal because I feel it helps with brain fog if I take it in the morning and for occasional stomach aches. This was a better value than a lot of them and worked almost as good. I still think the bulletproof activated charcoal was my favorite but it was a lot more expensive. I usually take 2 to 4 of these with a lot of water.
Expensive but it's what our dr suggested would be helpful for our daughter. Not sure if its making a difference - future tests will tell!
