For years I have been dabbling with the name brand deodorants as well as the more "natural" brands as well. I have spent oodles of time standing at the store and smelling which one I liked best. Which one would make me smell like a fresh meadow whilst running on the treadmill? Or maybe like rain in the meadow while pushing weights over my head. All this vanity to smell good sweating and never really understanding what I was doing to my internal functions.
Now that I'm older and wiser and dialed in to my health a bit more, I am on a mission to remove as much junk from my environment as possible. (Working really hard on healing thyroid issues!) My sister in law introduced me to a roll on and I'm here to say it works. Naturally Fresh fights off odor with it's mineral salts. It is hypoallergenic for us sensitive folk, paraben/pg free and fragrance free. It's extremely cost effective and easy to find at many stores. Keep in mind it will not keep you from sweating which is ok- that is our body's way of cooling down and we don't want to plug up our pores with antiperspirant!
Note that the product definitely keeps those pits from smelling fowl but does take some time to dry before putting on a shirt!
