i have not tried that product. i do however use "active liquid minerals" which has fulvic acid in it, is sourced from humic shale, and is ionic not colloidal, just like the product you linked.
there is the question of 100% fulvic acid (which the product you linked claims), vs. the active liquid product which states it has a 6% fulvic acid content. i spoke with someone who told me that thats just marketing and that nealy all minerals products that contain fulvic acid have about the same content. but that was just their opinion, i don't know if its true or not.
i love the active liquid produce and use it everyday. it gives my brain a good buzz.
if you try that product please post a message, just remember to add some lemon juice.
