You read about the application, which supposedly "enhances your mood and motivation!". It certainly sounds good, so surf your company website.
The website looks official. - did not even receive footnotes citing scientific journals. You are ready to buy the application online until you ask yourself: “What if this supplement really does not have any scientific evidence of its effectiveness? How can I tell the difference between supplements with solid evidence of their reported advantages over those who do not have any scientific support? "
Here are 3 steps to answer these questions:
Step 1: Go to
http://www.pubmed.org
which is National Medical Library (USA) where you can search for articles published in scientific journals that have been reviewed.
Why check out PubMed? Because the National Medical Library carefully selects only high quality magazines who offer value to medical scientists all over the world. Selection criteria are described in detail on this web page:
http://www.nlm.nih.gov/pubs/factsheets/jsel.html
Step 2: Once on the PubMed website, search for scientific articles using a common (scientific) name appropriate supplement. Supplement manufacturers must list the scientific name for their supplements on the label and in advertisements. Supplements often contain many ingredients, but usually only some of them provide the intended benefits. These are the ingredients that you want to evaluate - they are often the same ones that the manufacturer highlights in advertising.
Step 3: This is a move that some companies do not want you to know. Before you click the Search button on PubMed.org, limit your search to research that uses the correct research methodology with the right population.
The correct research methodology is randomized controlled process (double blindness, the placebo control group design fits this category), and the right population is people.
Specifying people is very important because you want to know whether the ingredients were demonstrated in the supplement for the advertised benefits of real living people — not just rats pushing levers for food pellets or in a one-person case study.
This does not mean that basic scientific research, which is often carried out first with animals, is unimportant. On the contrary, such studies usually serve as a critical building block for subsequent clinical studies with people. But basic scientific research does not provide scientific evidence to supplement the positive effects on human health. Such studies can only provide studies involving people using randomized controlled studies.
On the PubMed.org search page, Click the "Restrictions" tab located in the "Search" field You will see several drop-down menus. First click on the “Publish Type” menu, and then select “Randomized Controlled Trial”. Then click on the “People or animals” drop-down menu and click “People.”
Example
Morinda citrifolia is the scientific name of the popular ingredient in the dietary supplement. First PubMed Search for Morinda citrifolia without placing restrictions on your search.
How many results did you get?
Earl was 69 at the time I wrote this article. Looks impressive, huh?
But now find Morinda citrifolia after first placing the search restrictions as described above so that you receive only those studies that provide clearer scientific data for positive effects Morinda citrifolia ,
How many journal articles have you found search with specified limits? I found 1. Thus, of the 69 articles found on PubMed.org, only one gives some evidence for Morinda citrifolia beneficial effects.
It is wonderful that this study exists because it can be one of several studies that demonstrate that Morinda citrifolia provides health benefits. However, at present, at most could be said about Morinda citrifolia something like: "In one study, very preliminary evidence was given Morinda citrifolia health benefits with a narrowly defined group of patients. replicated by other research groups working with different groups of the population. "
Conclusion
Using the function "Restrictions" in the search menu of PubMed.org, consumers can identify additives that do not have scientific evidence of their effectiveness.
