Alpha-ketoglutarate (AKG) is a compound your body makes naturally. It sits at the center of the Krebs cycle, the process that turns nutrients into cellular energy. The molecule also helps build amino acids and handle nitrogen waste.
Supplemental AKG is taken to support energy output, bounce back from exercise, and maintain overall vitality. Researchers continue to study its connection to aging and metabolic function. Solid human data is still limited and inconsistent.
People usually take AKG as a powder or capsule. Empty stomach dosing may improve absorption. Some use it before a workout. Others prefer a different time of day.
