Word of mouth of the supplement

I think that the person to choose the supplement gathers information in various ways from now on. For example, I really watch the impression of the person who has taken the supplement, and then important things include that they think about whether you choose him in gathering information. I really take even a supplement declaring that I am effective so much, and, without an effect, it is not precocious despite the supplement which the supplement is enough for. Anyone takes a supplement, and the thing that wants to become healthy is written in various ways if I look at the official site of a company selling a supplement, but it is only an advertisement for sales promotion to the last. That means, the content written to the advertisement is reason thought to be the sales message that a supplement sales agency thought about.
Therefore, for the information that is more effective than it, I think that information of the person who took the supplement, it are the really most helpful. It is word of mouth. I do not know it when I read the word of mouth of the supplement because of course it is a personal opinion and a personal impression whether it applies to oneself, but there are the supplement which there was at all an effect in, the supplement that there was not an effect at all and the supplement which are extremely divided as it was said.
How about choosing it after having checked the word of mouth of the supplement on the Internet as one judgment material once when I choose the supplement? I think that it is very useful for selection of supplement.
