I've tried it and didn't notice anything happening....I suppose it depends where the toxins are and whether the charcoal can get in contact with them and act as a kind of sponge (like algin). If it works? I'd go for it. I have heard charcoal can have other benefits as well, but as JK8 said, it could also interfere with nutrient absorption and I would be careful about taking it long term. Even if you are taking it 2 hours away from food intake, I am not sure whether it's supposed to be a long term supplement.

I would google up about it! Find out about its benefits and risks and how long it can be taken for.
