Hi,
I am also using fulvic acid for HepC, and feel like something is working. I use Mike's choice. I am going in for testing in Dec. After much research, I think the concentrated fulvic acid is by far the best. I have seen a few brands out there like Denali Green and Mike's Choice, but there aren't many. I am putting my faith in Fulvic acid, because there is a lot of great research out there in the agriculture industry, and waste water treatment industry. There is not much out there for human use. In India and Russia it has been used for many years. In India it is called shiljat, and mumie in Russia. Other names are plant humification, sapropel. There are medical drugs being made from hummus matter mostly in Russia. The mineral concentrates differ from the region it is collected. Reishi mushrooms grow in the dense forest that are rich is fulvic acid.
