The new dietary supplement to boost metabolism Polilevo Spezial is a novel dietary supplement specifically developed to support the bodys own metabolic processes. Polilevo Spezial capsules and Polilevo Spezial drinking bottles contain the amino acids arginine and ornithine, and vitamin B6, which play key roles in metabolism. The amino acids arginine and ornithine are conditionally essential amino acids, meaning they can only be produced in the body to a certain extent. They are important for tissue metabolism in the liver and for the livers natural excretory function. Vitamin B6 is a water-soluble enzyme that is not stored in the body. It plays a key role in protein metabolism and is essential for many conversions (synthesis, breakdown, and transformation) of amino acids, the building blocks of proteins. Vitamin B6 is also a crucial factor in the synthesis of hemoglobin, the red blood pigment. It is therefore essential for maintaining a healthy nervous system, as well as healthy skin, muscles, and blood.
