What is L-Leucine 500mg?
L-Leucine 500mg by EssentialSeries is a food supplement in vegan tablets made from the amino acid L-Leucine produced through a vegetable fermentation process.
This is an essential amino acid that belongs to the group of branched amino acids, within the category of proteinogenic amino acids, i.e. those that make up protein structures.
Our L-Leucine, unlike other amino acid products on the market, has been obtained through a fermentation process from vegetable sources without animal raw materials, and no compounds of animal origin have been used in the production of the tablets, so that:
Our L-Leucine 500mg is a product suitable for vegetarian and vegan diets.

Why buy L-Leucine 500mg in HSN?
A very special amino acid for vegans
Did you know that...
A very common source from which amino acids are obtained in industry is bird feathers and mammalian hair?
Yes! Most of the amino acids sold by other companies are NOT suitable for consumption by vegetarians and vegans, as they are derived from animals.
In HSN we are constantly evolving to offer you the highest quality products possible, and one of the novelties we bring you is that:
All our essential amino acids come from vegetable sources, from them, through a fermentation process, we obtain the isolated amino acids of maximum purity.
And without animal ingredients!
The L-Leucine is a very important amino acid for vegetarians because of the small amount they consume in their diet, so our L-Leucine 500mg is suitable for vegetarians and vegans.
Which products can combine L-Leucine 500mg with?
If you are in definition you can combine it with our Creatine Excell 1000mg (100% Creapure®), excellent for this stage!
If you're bulking up, it can be great to use alongside products such as our Omega-3 Vegan.

Simple and effective muscle impulse
Daniel 16/05/2025
It is a direct and functional supplement. Ideal for those seeking to improve recovery and maintain muscle mass, especially in intense training or definition stages. It is easy to take and does not cause discomfort. Although it is more noticeable when combined with other BCAAs or proteins, it provides clear benefits on its own.
