Why you need amino acids

Amino acids are the building blocks of one of our fundamental nutrients, proteins, commonly found everywhere in the human body. There are some amino acids which the human body is capable of producing (non-essential amino acids), whereas the amino acids belonging to the other group (essential amino acids) are taken in with food. From all the different amino acids, only 20 contributes to shaping the structure of proteins. Amino acids are vital to all bodily functions such as digestion, liver function or wound healing. Amino acids maintain skin, ligaments, muscles, tendons, hair and nails. They also contribute to producing hormones, as well as neurotransmitting substances and enzymes. Besides, they also serve as a source of energy, as well as a carbohydrate and lipid-producing nutrient. The richest source of basic amino acids are foods of animal origin, whereas foods of plant origin often do not contain all of them.

Like all BioTech USA products, Glutamine Zero consists of safe and carefully selected ingredients.


Mix one serving (2 flat measuring spoons = 2 heaped teaspoons) with 150 ml water and drink directly after workout. On rest days, drink in the afternoon. Using a shaker is recommended.
