A supplement you may never have heard of may help you to build muscle and lose fat - so what is L-Glutamine, and what does it do?
There are so many different supplements on the market, all said to aid performance, that it can sometimes be hard to decide which you should actually use.
My experience is that often it is the least hyped that can be the most effective - rather than being taken in by the splashy color ads for the latest "mega" product, look instead at what the research says.
On these grounds L-Glutamine is well worth considering. You won't find big full page promotional spreads in your muscle mag, but you will find research showing that L-Glutamine can help facilitate the release of human growth hormone (HGH).
If you're not familiar with HGH, consider this - it plays two key roles in the human body, building muscle and burning fat. Its output peaks during puberty, begins to fall in your twenties, and by the time you are in your 40s has fallen to 1/10th its former levels. Clearly anything that can help boost HGH output will help with your workouts.
