The liver serves a critical role in glycogen storage and release, acting as a key metabolic organ. Glycogen is the stored form of glucose, and the liver can hold a substantial amount of it, primarily used to regulate blood glucose levels. The amount of glycogen stored in the liver varies based on dietary intake, energy needs, and individual metabolic health.

When examining various studies and physiological estimates, the liver typically stores approximately 75–100 grams of glycogen in a well-fed state. This storage is vital for maintaining blood glucose levels during fasting periods or between meals. When the body requires glucose for energy, the liver can convert glycogen back into glucose and release it into the bloodstream.

In contrast, other options would estimate liver glycogen reserves above or below this range, which do not typically align with physiological data gathered through research. This range underscores the liver's functionality in energy regulation and highlights its importance in metabolic processes.
