I put a tsp of DE in my coffee every day and a tsp on Lynn-DAH-the-Dog’s food. My nails used to chip and crack, but they don’t anymore, and Lynn-DAH has stopped shedding.
Of course, I use “food grade” DE.
probably wouldn’t want to eat “Sluggo Plus” though! LOL.
I put it on my outdoor dogs bed. She has way fewer fleas and noticeably less ‘scratchy’ now. I put it around her food bowls on the porch too to keep ants and other stuff out. We sprinkle it in the nesting boxes in the chicken coop.
I hadn’t thought to eat it. I’ll have to give that some thought though.
