Answer
Trustworthy credible, scientific information is more likely to come from scientific peer-reviewed journals than fro advertisements, anecdotes, and testimonials in articles published in popular magazines.
Articles published in scientific journals must go through a rigorous process of review and verification. Authors must be known and be available, if alive. Methods of experimentation must accompany results,conclusion, and statistical analytical methods used . These articles are not only peer reviewed, they are repeated in other labs by other investigators. If an experiment is not repeatable it is of little value, and is not publishable in a scientific journal.

Today, much scientific and pseudo-scientific information is distributed over the Internet. Sites that end in .com and .net cannot usually be trusted without further confirmation of information Sites that end in .gov, .org, or .edu are more trustworthy. Information from University websites and from the CDC, FDA, NIH etc can be trusted. Also,institutions like American Lung Association and The Multiple Sclerosis Society, Mayo Clinic and Johns Hopkins Hospital come from proven reliable source.
