Doc, the double blinded research didn't hide the facts, it found them, the powers that be hid the facts. It wasn't the data, it's what was done with it.
It isn't all that hard to get funding for non prescription medication, you just have to be able to write a good grant. That excuse is a facade because it is very easy to get funded for prescription products as the companies that make them fund the projects. You have to got to outside sources with these products and it takes more time and effort but certainly doable.
Most all of the clincal trials with nuetraceuticals show positve results. Most all of the blinded research trials show no effect.
This stuff may work, and I think some of these products do but was just pointing out a fact for those on here that don't know a lot about scientific literature. Just because it is on PubMed doesn't validate it. This was a poorly designed study.
