Do not take silica of ANY kind. It is a nano toxin that that accumulates in the cells. Silica, silicon dioxide, titanium dioxide are ALL nano poisons that accumulate in the cells and destroys cellular communication. It is an attack on your DNA. It is crystalline in nature and very difficult to to detox from. There is nothing inherent in your body that can break it down. It's just another scam from the "health food" industry. Silicas and silicon dioxide were banned from livestock feed in the '60's. Look it up! Take mag sulfat(epsom salt), mag chloride. Mineral salts will flush out the cells. Any chlorides.
