Drinking it straight is really bad. Using it in products not as much. Biotene toothpaste is a lifesaver to me. Literally keeps me without any pain or infections from existing decay.

But I definitely avoid tap as much as I can. Have pitcher filter and bottled water at home. The problem is the rabbit hole on water never ends. The big bad now is supposedly according to tests, bottled water of any kind is filled with dangerous levels microplastics even if the water is never exposed to heat or sunlight. So the only solution is buying glass bottled water or using a in line filter at home and storing in specific stainless steel bottles...buut not just any kind because apparently the coatings in most off the shelf bottles also have the same plastics

I regard all of this as disinfo. Drinking water has much more benefits than whatever test of the week says is horrible for you
