As if drinking multiple glasses a day wasn't bad enough, there was no quality control as to how much silver was in each glass. I believe it was Dr. Oz who told him that he had in effect tattooed his organs and skin from the inside.
No thanks. :-)
That guy also put it on his skin and then went inside a tanning bed! He was making silver chloride, which is well known for turning skin blue.
But there are articles claiming it can block absorption of some medicines. Not sure if science or speculation.
I bought a bottle just as a last resort last week. Just as a last resort. But I wish I could find good science one way or another.
