You can tell when it's a salesperson for a manuacturer because the name on the so-called "i got cured" stuff doesn't match the name of the poster, and it's usually way more factual than the average person gets! :)
I like Primal Defense, it really balanced my system. I could tell because I went through a healing crisis - rashes on my thigh ugh - and many symptoms disappeared. The manufacturer was recommended to me by my chiropractor, who's very much into healing the whole body. Since then I've heard from other people that they like their super green and probiotics best. My health food store is often sold out even! :)
I haven't tried the other stuff, simply eating right, bowel management, and some Liver Flushes were enough to resolve my issues. Whew! :)
