zeolite.com has the best. Powdered zeolite is far superior than liquid. I've been taking it for about a month and my skin looks better. But i'm only taking 1.5 scoops a day. As far as dosage goes, just 1-3 scoops is what's recommended with this product.

Another thing.. I've noticed that since i've been taking it.. when I wake up in the middle of the night to take a piss I feel more tired. Zeolite isn't supposed to have any side effects so thats why I attributed these symptoms to my body adjusting to the change in heavy metal status.

What i'm trying to say is this stuff works. Expensive as shit though O_O
