Glutamine Zero, Blue Grape is a flavoured post-workout powder formula. In 90%, the product's active ingredient is the conditionally essential glutamine amino acid. Amino acids are the building blocks of one of the fundamental nutrients, proteins, commonly found everywhere in the human body. 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. It is recommended to 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. Made in a plant that manufactures milk, egg, gluten, soy, crustaceans, sulphur dioxide and nuts containing foods.
