Know Your Bodybuilding Supplement - L-Tyrosine
L-tyrosine is a non-essential amino acid that plays a role in the creation of protein. The body can make it from the amino acid phenylalanine but nutritional sources include animal meats, wheat, oatmeal and seafood.
It performs a multitude of important roles in the body including the alleviation of depression, enhancement of thyroid efficiency, strengthening of the immune system, prevention of neurological degeneration and protection of the skin.
Bodybuilders find it useful for several reasons:
1. It offsets the stress and fatigue associated with intensive training.
2. It helps in the retention of muscular protein.
3. It heightens mental alertness thus helping to offset mental fatigue.
With any amino acid supplement overdosing can lead to weakness and nausea so care should be taken in applying small doses and increasing them gradually until an optimum level is reached. Bear in mind that many protein powders and other supplements are fortified with amino acids so check the labels carefully. The manufacturer's instructions should be followed in all instances.

3 Steps to Identify Supplements that Lack Scientific Evidence
You read about a supplement that allegedly "Boosts your mood and motivation!" That sure sounds good so your surf over to the company's web site.The web site looks official--it's even got footnotes citing scientific journals. You're ready to purchase the supplement online until you ask yourself, "What if this supplement doesn't really possess any scientific evidence for its efficacy? How can I tell the difference between supplements with solid evidence for their reported benefits versus those lacking any scientific support?"Here are the 3 Steps to answer those questions:Step 1: Go tohttp://www.pubmed.orgwhich is a National Library of Medicine (United States) web site where you can search for articles published in peer-reviewed scientific journals. Why check PubMed? Because the National Library of Medicine carefully selects only high-quality journals that offer value to medical scientists around the world. Selection criteria are detailed on this web page:http://www.nlm.nih.gov/pubs/factsheets/jsel.htmlStep 2: Once on the PubMed web site, search for research articles using the generic (scientific) name of the supplement in question. Supplementmanufacturers must list the scientific name for their supplement's ingredients on thelabel and in advertisements. Supplements often contain many ingredients but usually only a few provide thepurported benefits. Those are the ingredients you want to evaluate--they are often the same ones the manufacturer highlights in advertisements.Step 3: This is the step some supplementcompanies don't want you to know. Before you click on the "Search" button at PubMed.org, limit your search to studies that utilize the right research methodology with the right population. The right research methodology is a randomized controlled trial (the double-blind, placebo control group design fits under this category) and the right population is human beings.Specifying human subjects is important because you want to know if the ingredients in a supplement have been shown to produce the advertised benefits in real live human beings--not just in rats pressing levers for food pellets or in a "case study" with one person. This is not to say that basic science research, which is often conducted initially with animals, is unimportant. On the contrary, such research usually serves as a crucial building block for subsequent clinicalresearch with humans. But basic science research does not provide scientific evidence for a supplement's beneficial health effects on human beings. Only research with human subjects, using randomized controlled trials, can offer such evidence. On the PubMed.org search page, click on the "Limits" tab located under the "Search" box. You will see a number of drop-down menus. First click on the Publication Type menu and then select Randomized Controlled Trial. Next click on the drop-down menu labeled, Humans or Animals and click on Humans.An ExampleMorinda citrifolia is the scientific name for a popular ingredient in a nutritional supplement. First search on PubMed for Morinda citrifolia, without placing Limits on your search. How many results did you receive? The count was 69 at the time I wrote this article. Looks impressive, huh? But now search for Morinda citrifolia after first placing Limits on the search as described above, so that you receive only those studies which provide more definitive scientific evidence for the positive effects ofMorinda citrifolia. How many journal articles did you find searching with the specified limits? I found 1. Thus, out of 69 articles found on PubMed.org, only one provides some evidence forMorinda citrifolia's beneficial effects.

All-Natural HGH Releasers- Does Neugenisis Really Work?
I began a quest to examine over 25 "leading products" in capsule, spray, or tablet form within the HGH field. Efficacy was examined, as well as product marketing approach, manufacturers reputation, and overall customer support and guidance. These were several areas of concentration throughout this review. I have found an unfortunate amount of "information" or "review" sites that fail to share actual valid or informative content on HGH, its importance, or role in the aging process. There seems to be many sites promoting their own products under the guise of certain "physician or nurse" type endorsers in an effort to claim legitimacy.
