Low quality colloidal silver in VERY large amounts can be somewhat of a problem in the sense that it can build up in the system. Though even in these rare cases it is not really dangerous to health. In fact all the rich people used to have silver cups, plates, silver ware etc because it was so healthy.
What's even more awesome is that Nascent Iodine which is an essential nutrient for the body of which its benefits are numerous , is the best at detoxifying heavy metals in the body. Not just silver but much more toxic heavy metals like murcury or lead.
So even if u did take a LOT, with The Garden of Eden Nascent iodine you can improve every day health, plus detox ALL heavy metal build up!
Epic win!
