ArginineThe supplement that gets my vote for biggest come back of the decade is arginine.A decade ago it had a brief day in the lime light with athletes as a supplement thatmight stimulate growth hormone.However Cheap Jerseys Wholesale , its use as a GH releaser never materialized into new muscles for users,so it quickly fell out of favor. Recently however, there has been a resurgence ofinterest in arginine by athletes and supplement companies. This is due to recentfindings showing a long list of possible uses with arginine, ranging from possibleprotection from heart disease, reducing cholesterol, to increasing blood flow.The reason for this surge of interest in arginine by researchers is its connection to a molecule called nitric oxide (NO). NO is the new super star molecule withresearchers as it appears to play a role directly or indirectly in almost every aspect of human physiology.Arginine is a key component of the NO production pathway (arginine serves as thesubstrates for the nitric oxide synthase enzyme, which produces citrulline and NOfrom arginine) which is essential for a cascade of reactions involved invasodilation and cardiovascular function.Recent data suggests arginine may have some legitimate uses regarding health andwell being. For example, the lining of artery walls called the endothelium needs todilate and contract effectively. NO is essential to this function and several studieshave found arginine supplements at 8-20 grams per day restored endothelialvasodilation in the coronary arteries and may improves overall blood flow which isimportant for people suffering from ischemic issues.Another study suggested that arginine supplementation greatly improved penilefunction in men with penile dysfunction as NO is essential for blood flow involvedin getting an erection.Arginine has shown a very good safety profile to date and appears to have virtuallyno toxic effects. From an athleticmuscle building point of view, things becomemuch less clear. Early studies suggested arginine could increase growth hormonelevels Cheap NFL Jerseys , but in truth (a) these effects were found using very high doses and wereintravenous and (b) short lived spikes in GH don't appear to have any positive effects on muscle mass or performance in healthy athletes anyway. Also, NO is amessenger molecule related to virtually just about every pathway in the humanbody one way or another.Therefore, simply raising NO will have both positive and negative effects, most ofwhich are not known at this time. It may be shown that the improved blood flowmight increase oxygen saturation of tissues making it a good candidate forendurance athletes or a pre workout supplement for bodybuilders, but that has yetto be proven.Unfortunately the data that has examined effects in athletes is lacking and somesupplement companies are far overstating arginine's potential role in musclegrowth or performance. From a health perspective, arginine may have some realdirect uses for people with high cholesterol, coronary artery disease, ischemic(meaning a reduced blood flow and oxygen delivery to tissues) and even men witherectile dysfunction. As for athletes, the jury is still out but arginine is one of those supplements to keep a close eye on for sure. At this time Cheap Jerseys , I would not recommend it to athletes however for increasing either muscle mass or performance. For that use, it gets a thumb's down.BCAA'sIn the world of amino acids, the structural "building blocks" of proteins, there areseveral classes and types of aminos. For example, we have the essential aminoacids, the non-essential amino acids, the conditionally essential amino acids andthe branch chain amino acids (BCAA).The essential amino acids are deemed as such because the body cannot manufacture them and they must be supplied by the diet. The non-essential amino acids can be made from the essential amino acids, and thus don't have to be supplied by the diet for survival, though many non-essential amino acids play essential roles in health and metabolism in their own right.The conditionally essential amino acids Wholesale Jerseys Cheap , so named because during certain periods,such as infancy or certain metabolic states, can be considered essential for thatperiod of time. The branch chain amino acids (so named because they branch offanother chain of atoms rather than form a straight line as other amino acids do) areleucine, valine and iso-leucine.The BCAA's are the amino acids that are primarily used (oxidized) during exerciseand make up to one third of the amino acids in muscle tissue. It has been knownfor a long time that BCAA's play a critical role in the turn over of lean bodytissues (muscle) and is muscle sparing (i.e. anti-catabolic) in a variety of muscleswasting states. Of the three BCAA, L-leucine appears to be the most important topreserving hard earned muscle mass; intense exercise and certain disease stateshave been shown to eat up a great deal of L-leucine.So far so good! On the research front, some studies have found the consumption of BCAA before endurance exercise may decrease the rate of protein degradation andmay have a sparing effect on muscle glycogen degradation and depletion of muscleglycogen stores.However, leucine supplementation at 200 mg per kg of bodyweight prior toanaerobic running exercise (sprinting) did not improve performance.Truth is, research to date with BCAA's and performance has been contradictory atbest. One of the major drawbacks of the BCAA's as a supplement is dosage. Ittakes very high doses to see any ergogenic effect, assuming there are anyergogenic effects to be had Wholesale NFL Jerseys , as studies are still limited and or contradictory.Although BCAA's supplementation may or may not be effective, it is costprohibitive when one factors in the amounts needed. The good news however isthat proteins, in particular whey protein, is very high in BCAA's and this may beyet another reason whey is the so popular with athletes and so impressive in theresearch.As amino acids relatL.
