We all know that there are 9 essential amino acids, which are important in promoting protein synthesis, boosting lean muscle growth, and enhancing recovery after exercise. The more targeted exercise we do, the greater our need for the right mix of amino acids and the optimum levels in our supplements.

So keeping up with research into amino acids is always a good call, because if there is something new on the market, then we want to know about it. Whilst this piece of research won’t help us to make any changes to our supplement regimes at the moment, it is noteworthy in itself.

What’s this research about?

Well as you already know, arginine and leucine are two of the 9 essential amino acids we need for lean muscle growth and scientists have been trying to nail down how our body detects the level of these amino acids.

This is important because if we know what triggers and inhibits muscle growth, scientists can use this information to better treat conditions involving muscle atrophy and disease related weight loss. Currently all that can be done to treat these problems is to suppress the entire detection pathway, which is too general for targeted treatments and creates unwanted side effects as well.

So whilst scientists already know of a pathway in our body that regulates these amino acids, it doesn’t know the exact sensors that detect individual amino acids. What researchers have now done is to identify the protein sensors for both arginine and leucine.

How does this affect us?

Leucine is one of the key components in the growth regulating pathway and when the levels of amino acids are too low in our body, the researchers have found that a particular protein that is very sensitive to leucine levels, binds with a protein complex to inhibit the growth pathways.

This in turn, reduces cell growth. So the amount of leucine in our body directly influences lean muscle growth. Of course further research is needed into these pathways and how the protein that senses leucine can be used to inhibit or trigger muscle growth, but so far their work is very interesting.

It may even be possible in the future to design drugs that directly interact with these growth pathways. This could be achieved by creating drugs that imitates leucine and artificially increasing or decreasing the activity in the growth regulating pathways.

Certainly this will be an important step forward in treating diseases involved in muscle wastage, but it also has some interesting potential for people involved in intense sports, where muscle growth needs to be enhanced. So if you are interested in including leucine or any of the other essential amino acids into your diet, choose from a wide selection of amino acids from Supps R Us and start optimising your muscle growth today.
