NoctiBurn is a supplement composed of essential amino acids that support the development of growth hormone (GHG). By supporting human growth hormone during the night, you can "burn fat" while you sleep. What is Human Growth Hormone? Human Growth Hormone (HGH) is a protein produced by the pituitary gland. It is a muscle-building, fat-burning, and youth hormone, giving the body a youthful appearance. Its main functions are to increase height and muscle mass, control the body's metabolism, and reduce body fat. The amino acids contained in NoctiBurn support the production of Human Growth Hormone to promote fat burning during the night*. Nocti- comes from the Latin word "nox," meaning night, and "Burn" is an English word that means to burn. Amino acids are protein components that are necessary for the proper functioning of the body. Essential amino acids are those that the body cannot synthesize on its own. This means that the only source of these amino acids for our body is direct consumption through diet or supplementation. Arginine, also known as L-Arginine, is an amino acid used in protein biosynthesis. Biosynthesis is the production of a chemical compound by a living organism. Like other amino acids, L-Arginine plays an important role in building proteins. On the other hand, L-Lysine is an essential amino acid, which means that the body cannot manufacture it. It must be obtained through diet or supplementation. Lysine is one of the best-known amino acids and is an essential component of all proteins. Recommended Use: To burn fat while you sleep, take 4 NoctiBurn capsules each night before bed.
