It is all related to the amount you take, and the concentration of the sodium chlorite used.
The 3 drop dose when following the Miracle-Mineral-Supplement protocol is repeated each hour of the day. If you go for 8 hours, you end up ingesting 24 drops. This is a lot more than the 10 drops used in 1 liter of water that is used once a day.
This only addresses the chlorite. In addition, there are side effects involved with the concentration of the dose. The higher the concentration, the more stress is put on the body.
