I want product that is not addictive and something I can take daily as daily supplement.
Well, you're making the mistake of assuming that something is safe, effective and non-addictive just because it is a dietary supplement. In point of fact, being declared a dietary supplement EXCLUDES a product from most requirements of efficacy and purity. If someone claims that their dietary supplement can do X, Y and Z, then (under US law) it is no longer a supplement, but is a drug and is regulated by the FDA.
Supplements (in the U.S.) exist in this loophole. As long as they don't make health claims, they aren't under the jurisdiction of the FDA. Without the accompanying government regulations requiring proof of safety and efficacy, there is no guarantee that what you're being sold is safe, effective or even what the manufacturer claims it to be.
For better or worse, you simply have to trust them.
So, make your own decisions based upon your trust level. Personally, I research things before I put them into my body. I get a good idea of what the literature and annecdotal reporst say, then purchase from a manufacturer with a good user reputation. I'm not sure that there is more that could be done (other than conducting my own lab tests).
If you're going to take these things, you do so with your fingers crossed.
