Food Grade Diatomaceous Earth is 89% Silica.
It was established in the 1940s that life can’t exist without Silica. In her book “Water & Salt” Dr. Barbara Hendel states: “Silica is the most important trace element in human health”.”
Silica plays an important role in many bodily functions and has a direct relationship to mineral absorption. The average human body holds approximately seven grams of silica, needing significantly more silica than other important minerals such as iron. Most people are, in fact, silica deficient.
Among other things, enough silica in the body is vital enough for calcium absorbtion to render calcium supplements ineffective and even detrimental if the body lacks enough silica. Food Grade Diatomaceous Earth is an excellent natural and organic source of silica.
