L-Leucine can be a valuable tool in not only muscle building but can also play a critical role in weight loss.



 What is L-Leucine?

L-Leucine is an essential amino acid, which means that the body doesn’t produce it naturally.


So for the body to get this key amino acid in the system it has to pull them from a variety of foods. Those foods typically include protein rich animal foods like beef, chicken, fish, dairy and eggs.

What exactly does L-Leucine do?

Recent research has discovered that L-Leucine acts in a unique way: it can help burn fat without burning muscle.


That’s a bit of a head scratcher because aminos are responsible for getting nutrients to the individual cells to burn – but usually aren’t discretionary about what nutrients it takes to the “furnace”.


As mentioned previously, L-Leucine seems to be different; they found that L-Leucine actually spares the muscle proteins, leaving them to help build and increase muscle gain and mass.

Are there any side effects?

At this time there have been no known major side effects with taking L-Leucine.


Usually when a substance like L-Leucine is produced organically in nature, and if proper dosage amounts are used, then the chances for side effects really drop. That is consistent with L-Leucine.
