Fulvic acid is found in a liquid form along with mineral colloids。 Fulvic acids are poly-electrolytes and are unique colloids that diffuse easily through membranes whereas all other colloids do not. Fulvic acid supplements consisting of a neutral pH are very weak fulvic compounds and do not deliver the benefits of free form fulvic acid (fulvic acid that remains unreacted with other substances or unboundto minerals) that exhibits a much higher concentration and lower pH. Fulvic acid branded as “ionic” is not free form fulvic acid, more accurately they are fulvic compounds or fulvate salts. According to the International Humic Substances Society all fulvic acids are colloids.
