Alpha-ketoglutarate is a key compound in the Krebs cycle, which is essential for energy production in cells. It plays a crucial role in converting carbohydrates, fats, and proteins into usable energy. This compound is also involved in amino acid synthesis and the regulation of cellular metabolism. In addition to its metabolic functions, alpha-ketoglutarate is studied for its potential health benefits. It may support muscle recovery, enhance exercise performance, and improve overall metabolic health. Some supplements containing alpha-ketoglutarate are marketed for these purposes, although more research is needed to fully understand its effects.
