Diatomaceous earth (food grade) is a fine, silica-rich powder derived from the fossilized remains of tiny aquatic organisms called diatoms, and it has a long history of use in folk wellness traditions. Research suggests that food grade DE may support digestive health by gently promoting regularity, and a small study published in the European Journal of Medical Research indicated that daily intake was associated with modest reductions in blood cholesterol levels over several weeks. Some preliminary findings also point to its trace mineral content, particularly silicon, as potentially beneficial for nutritional support, while its porous structure has led to interest in its possible detoxification and antimicrobial properties. However, human clinical research remains limited, and most evidence comes from small trials or traditional use rather than large-scale studies.
