I listen to the podcast that Martin has with the founder of this company, Micah, and what I heard about zeolite being able to detox you from heavy metals and other things and well as lifting your brain fog. So I ordered it and we both started taking it. We both noticed that it really helped with the brain fog. It's also helping me detox from cigarette smoke as I grew up in the 60's in a household that smoked like trains, I didn't realize that it would do this, I didn't realize that that smoke was locked in my body but after a couple of months, I began to smell cigarette smoke. Either of us smoke and we had bought a new house too. I smelled it everywhere I went, my husband never smelled it. Then I called Martin and he confirmed my suspicion about the cigarette smoke. We will continue to take this product! But give it a few months to work.
