When I was studying for the master of agriculture degree I noticed every reference to fluorine for any species of livestock was fluoride poisoning. Never a reference to fluoride deficiency. I asked one of the professors of animal nutrirition if there is ever a reason to supplement livestock feed with fluoride his response was priceless. “You are going to stir the pot.” This was back when the county was making plans to fluorinate the tap water.
This is why I have a fluoride pre-filter between my tap and my UltraStream water filter. And you should too!
