Diatomaceous Earth Online is proud to offer a natural product of the highest quality. Our amorphous (freshwater) silica is chemical and additive-free, and contains no toxic levels of any element. It has a high level of immediately soluble silica, and is completely safe for use in accordance with the dosage rates suggested on this website.
CAUTION: Do not confuse natural silica or food-grade Diatomaceous Earth with industrial grade DE which may contain crystalline silica used in filtration systems. Crystalline silica is dangerous and must not be consumed by humans or animals, or used on gardens or agricultural crops.
As DE is a natural product, mined directly from the ancient deposits within dried lake beds, the exact scientific analysis will vary slightly from batch to batch. Because it is a natural product, no DE will be “100% pure” but will contain varying levels of silica and other minerals.
