What it is
Fulvic acid is one of three humic substances, alongside humic acid and humin, formed over long periods as plant matter breaks down under microbial action. Of the three it has the lowest molecular weight, the highest oxygen content, and stays soluble at any pH.
In shilajit it is a defining constituent rather than an additive, which is why its content is one of the things measured in every ASCENTIALS batch.
