I don’t see how this is legal, but people on Tik Tok peddling miracle “medicine” are becoming more common every day. No FDA approval, no research. Just their marketing hype and false promises. This one, lady is showing some sort of probiotic and claiming it can help people suffering from severe acid reflux and gastrointestinal reflux disease or GERD, replacing medicine that has been tested for decades.
It’s also heavily used in treating and keeping proper pH balance the water in swimming pools, hot tubs and various other types of aquatic entertainment. I used to have to lug 50 lb bags of it to the chemical shed.
