L-Citrulline or Citrulline Malate: in the body, citrulline acts as an arginine precursor, meaning it's used in the production of arginine. Arginine helps stimulate nitric-oxide (NO) production, which acts as a vasodilator to open up blood vessels and increase blood flow to muscle.
Glycerol Monostearate: taken orally as a fitness supplement can prevent dehydration during exercise, improve exercise performance, and increase muscular pumps during physical activity.  Upon oral consumption, glycerol is rapidly absorbed and distributed throughout body fluids, except in the brain and eyes, and then is slowly metabolized via the liver and kidneys.
Arginine alpha-ketoglutarate (AAKG): is a salt of the amino acid arginine and alpha-Ketoglutaric acid. Nitric oxide supplements usually contain arginine alpha-ketoglutarate, which purportedly increases and maintains a high level of nitric oxide in muscles. In theory, the production of nitric oxide from the supplemental arginine promotes vasodilation (dilation of blood vessels, which in theory may make you look vascular [veiny]), which increases blood flow, oxygen transport, and delivery of nutrients to skeletal muscle during resistance training. This purportedly results in dramatic increases in muscle size and strength.
Maltodextrin: is a type of carbohydrate synthesized from grain starch, corn, potatoes or rice. Despite its classification as a complex carbohydrate, maltodextrin is quickly absorbed by the gut and can elevate blood sugar faster than glucose. On the glycemic index, a relative scale of how quickly ingested carbohydrate affects blood sugar, maltodextrin ranges between 85-105, where the standard glucose is set at 100.
Dextrose: is an extremely fast-digesting simple sugar, it raises blood glucose levels quickly, causing a rapid spike in nutrient-transporting insulin into the bloodstream.
Sodium chloride: is the chemical name for salt. Sodium is an electrolyte that regulates the amount of water in your body. Sodium also plays a part in nerve impulses and muscle contractions.
