Q. I recently heard that aluminum causes Alzheimer’s disease and my antiperspirant contains aluminum. What do you use?

A. While some studies have indicated an association between the presence of aluminum in the brain and Alzheimer’s disease, I know of none that indicate aluminum is causative. Nevertheless, I understand your concern and would rather be on the safe side myself since options are available. For example, have you considered using a natural deodorant crystal in solid, spray, or roll-on form? That’s what I use.
