Some companies claim they add fulvic acid to their humic minerals, others say not to do this. What is the truth behind these claims?
You would not add fulvic acid to humic minerals because then the solution would separate. You can shake it, but it will not be stable, and the settled humates will become “clay-ey” and indigestible. That’s how fulvic acid is made (see above), by adding acid (any kind, even fulvic) to humic minerals. Those who claim that their product contains humic and also fulvic acid are simply trying to get as many “buzzwords” as possible into their advertising. There is no such thing as a humic mineral solution that is not mostly fulvic acid!
