Creatine is a nitrogenous organic acid that helps supply energy to cells throughout the body, particularly muscle cells.2 Creatine makes up about 1 percent of the total volume of human blood.2 Between 1.5 and 2 percent of the body’s creatine store is converted for use each day by the liver, kidneys, and pancreas.3 It’s then transported through the blood and used by parts of the body for energy.3 The average person needs between one and three grams of creatine per day.4 Around half of this comes from the diet, and the rest is produced by the body.1,5 Increasing creatine levels via supplementation may support cells’ energy levels.
