I have tried it recently, and am currently on a maintenance dose of several pills every other day. I feel like it was one of the missing links in my candida and eczema program, and that the most success that I have had over my 10-15 year process (quite a bit of it documented in Curezone)has been my recent protocol that included this product.
I continue to use it because I like the idea of it keeping the yeast in my system in a form that is easy for my immune system and gut flora to control.
Dr. Jeff on the Ask the Candida Expert forum explained that yeast in the fungal form is highly adaptive and will often change form when under attack by anti-fungals and even by an extreme anti-candida diet.
It was through the use of the SF722 that I learned of the connection of my sinus issues to fungus as my sinus issues were among the first to react and then to heal when I first began to use this product without any other products. Also, a few weeks into using it was the first time I didn't see candida strings/ropes during my coffee enemas, since I first began doing coffee enemas about 10 years ago. I also found out that the goosebumpy chicken skin on the back of my arms was due to candida, or at least went away fairly quickly while consuming only the SF722.
I feel like the use of this product consistently for a couple of months made everything else I used (probiotics, l-glutamine, hcl, immune boosters, etc)much more effective. There was also something to the timing and order of supplementation (as recommended by Jeff Mccombs)that made this protocol much more successful.
Although this product is expensive, it will always be a part of my arsenal of weapons in my overall health maintenance program.
Other than having cut out sugar-laden drinks, I am eating a regular diet and feel the best I have felt in over a decade, and this is one of the important products that I feel has helped to achieve that.
