Ive been doing some research into humic & fulvic acids and thought I would post some info that I came across as they sound like they could potentially help some of us. They are derived from decomposed soil matter and are quite interesting substances apparently with many properties eg they are supposed to be powerful electrolytes & antioxidants, have anti-viral properties and help the body to absorb minerals better amongst other things. Humic acid in particular, because of its larger molecular size compared to fulvic acid has strong anti-viral actions ... it acts like a viral fusion inhibitor by stopping viruses binding to cells according to Dr Richard Laub who is a PhD chemist and conducted research into Humic & Fulvic acids for 10 yrs....dont know if he is still doing this now. There is an interview with him (in the first link below) from back in 2005 where he says that humic acid in particular has been shown to act as a broad spectrum anti-viral against various viruses including some of the influenza ones and herpes too, and there is also anecdotal evidence that it has helped in HIV/AIDS cases alongside the regular drug cocktails. I know that some health supplement companies have been selling fulvic acid as a supplement for many yrs now but I havent really heard many, if any at all stories of people with ME/CFS using them. Has anyone tried taking them? If so have u gotten any benefits? Here is the website with the interview with Dr Laub from 2005 - go to the top left hand corner of the main page and it will take u to the interviews.. http://www.humichealth.info/ Other stuff I came across with research info on Humic & Fulvic acids.. http://www.zeohealth.com/FulvicStudy.pdf http://vfi-humic-acid.com/ http://www.ncbi.nlm.nih.gov/pubmed/18241960 Ive been taking a fulvic acid supplement for the last few days and I'm pretty sure its doing something but nothing major. Going to try humic acid next once Ive finished this bottle to see if it works any better.
