yes i have heard about this. it gets murky as many claim to be selling 10 or 50 or even 100% fulvic acid, and yet i have also read that this is marketing, that the fulvic acid concentration can only be so high, and that 100% is not at all accurate. so i don't know who to believe. i also wonder about this product, does it dissolve in water or juice? it does look interesting though. i don't know how much 14 pounds is, is that expensive for a supplement?
ana linked this one, this is the product she uses, don't know if its available in the UK tho.
