How much do I take a day and how much water do i use?
Silica is poorly absorbed so taking even a capsule of it will end up with waste. So I recommend keeping it in a large container of water and letting it settle out. The water will dissolve a little of the silica forming orthosilicic acid, which is what he body uses. Just leave the silica in the container and when you add more water more silica will be dissolved. This way you also absorb a little silica each time you take a drink of water:
Donna Gates (of Body Ecology Diet fame) says to avoid this, for it grows "wild cultures" that can be harmful. Is this true? Thanks!
"Wild cultures" is really vague. Technically any bacteria in your intestines can be considered "wild cultures" as they are all introduced to the intestines. The intestines are sterile prior to birth. Cultured foods promote the growth of the beneficial bacteria in the intestines though, meaning the cultured foods themselves are beneficial.
