Your body can store about 100 grams of glycogen in the liver.
It can also store glycogen in the muscles, about 1 to 2% of the muscle mass, which on average means around 400 grams.
Glycogen is also stored in very small amounts in other tissues, such as brain, kidneys, and even blood cells.
Depending on your muscle mass and ability to store glycogen, your body may store from 500 to 600 grams of glycogen.
