The gym L-Glutamine has long been known and loved. He attributed all kinds of positive effects and it is not only the athletes to build muscle and improve performance. It also has an influence on the metabolism and to strengthen the immune system.
It is now being used because it can alleviate symptoms occurring or result in faster recovery even against certain diseases such as cancer.
I hope that the powder boosts my metabolism slightly, so far I can not see any ground-reaching changes, but I use the L-Glutamine powder also only recently. Anyway, I feel comfortable with it and the price is reasonable, especially as it requires only small amounts and so holds a 500g tin long.
