Essential Amino Stack


Amino acids are the building blocks of our muscles and the building blocks of all proteins.

Light knowledge


It is often difficult for athletes to obtain sufficient essential amino acids from basic food. That is why there is Essential Amino Stack, which contains the 8 essential amino acids in an optimal ratio and free form so that they are quickly absorbed by the body. In addition, Citrulline Malate has also been added to the Essential Amino Stack.

There are 20 amino acids in our diet. In contrast, the body makes 12 of 20 amino acids. The other 8 (Leucine, Isoleucine, Valine, Lysine, Phenylalanine, Threonine, Histidine and Methionine) the body does not make. These are essential for the proper functioning of the body, so we must get them through food or supplements.


Essential Amino contains only the purest ingredients, no unnecessary fillers or sugar are used. This was shown by the test in the field of contamination: all values ​​were well within the reference and therefore met the qualitative requirements. A small amount of sweeteners and natural colorings have been added to give the product a nice and fresh taste.

Nutritional values

Essential Amino Stack is 100% vegetarian and contains only the purest form of essential amino acids. These are composed in the most optimal proportion and in free form and are therefore quickly absorbed by the body.

Using the Essential Amino Stack

Amino Stack is very suitable for supplementing your amino acid needs during the day. You can get 500 doses from the 45 gram jar.
