I highly recommend the crystalux brand of natural deodorant. I stopped using the "store" stuff with the aluminum in it a few years ago when I heard it was bad. I tried a few things and the crystalux has been the best I've used. My family are heavy 'sweat'ers but it doesn't smell. And I don't get as hot as I used to since the aluminum isn't clogging my natural heat releasing pores.

It really can be used anywhere on the body, including feet, and doesn't stain like some of the mineral deodorants do. I just love it and couldn't live without it. I buy it in bulk.
