For the past several decades, researchers have been obsessing over human growth hormone.  As they continue their research, they constantly are adding new discoveries to the list of benefits from HGH.  Considering all the benefits of HGH, it is no surprise that so many studies focus on how to increase HGH production naturally.

Even though the term “HGH releaser” didn’t exist at the time, a major study conducted in 1981 lay foundation for these supplements.  A group of Italian medical researchers gave male volunteer subjects a dosage of amino acids and then measured their HGH levels.  The men experienced a significant increase in HGH levels after taking a combination of the amino acids L-Lysine and L-arginine. However, when the men took just one of the amino acids, they did not get the increase in HGH levels.  This paradox just shows how complicated HGH production is in the body.

Since then, there have been various other studies on HGH releaser ingredients.  The studies are overwhelmingly positive and show that these supplements can cause significant increase in HGH production.  Because the HGH is being produced naturally, there have not been the side effects or risks which come with HGH injections.

Scientists have already identified dozens of HGH releasers.  When choosing a HGH releaser formula, look at the ingredients list and do some research. You can do a search through scholarly databases, such as by using search engines like Google Scholar.  There, you will be able to find out whether the listed ingredient is really as good as the company claims.  Here are just some of the many case studies about HGH releaser ingredients.
