I just want to make a few last comments regarding the DAn-Active commercial I've been discussing over the last few days, which, by the way, you can watch here.
One aspect is the initial statement about "stress". There is NO evidence that Dan Active decreases stress effects on the immune system. And they never visit this topic on their website. So I'm not sure why they even mention this fact at the beginning of the commercial.
Secondly, they say that "70% of your immune system is in your GI tract". Even if this is true, that doesn't mean that your GI tract is primarily responsible for the health of your immune system. The GI tract is HUGE, so naturally you would have a lot of immune cells there. Their implication is that this is where our immune system mostly "hangs out".
Finally, they claim it can give your immune system a "boost". I don't know if its just me, but the takeaway message appears to be that you can down some of this stuff, and then just inhale all the virions you want, and this will somehow reduce the chance of infection, which is bogus.
Also, they don't mention the sugar content, which is probably rotting their kids' teeth. Its flavored with some sweet strawberry crud.
I think the FCC needs to regulate these commercials better, especially if they're going to hawk this stuff as medicinal.
