Fulvic acid, also known as fulvic acid or fulvic acid (mineral-derived), is an extremely complex black organic substance with bioactive properties. It is the ultimate aerobic decomposition product of all living matter, possessing unusual characteristics and abilities to alter and transform molecular structures, encompassing almost all organic and inorganic substances in nature. It also possesses the property of fusing molecules. It is the ultimate microstructure after the decomposition of all active biological substances, and its structure also contains potential solar energy substances, originating from photosynthesis. Solar energy helps promote the special properties and bioactivity of fulvic acid. Fulvic acid deposition comes from the decomposition of large amounts of vegetation by microorganisms. It is a naturally occurring organic substance, entirely derived from decaying ancient plants and animals. It is lacking in modern food crops and is extremely important for human physiological activity.

Fulvic acid is the most excellent organic acid discovered in nature to date. It is part of the humic structure in fertile compost soil, and its content is extremely rare. Fulvic acid is acidic and can only be produced in trace amounts in undisturbed primeval forests by millions of beneficial microorganisms in soil environments containing decaying plant matter and ample oxygen. It is a highly oxidized, small-molecule humic acid with numerous active functional groups, soluble in acids, alkalis, and water, easily absorbed and utilized by the human body, and possesses the best health benefits.

Structure

Studies have found that fulvic acid has a lower molecular weight than humic acid, containing fewer carbon atoms and more oxygen atoms in its molecular structure, and its acidic functional group (-COOH) content is also higher. Furthermore, fulvic acid contains more ketone carbonyl groups and hydroxyl groups than humic acid, thus exhibiting stronger acidity in aqueous solutions compared to humic acid. The exact molecular structure of fulvic acid is not yet fully understood; however, a structural model of a certain type of fulvic acid, based on the carbon skeleton structure of humic substances, is shown in Figure 1. Fulvic acid typically contains 40% to 50% carbon, 4% to 6% hydrogen, and 44% to 50% oxygen.
