What is Alpha-ketoglutaric acid (AKG)?

Alpha-ketoglutaric acid (AKG) is a naturally occurring compound in the Krebs cycle that helps cells produce energy. It is also involved in amino acid and nitrogen metabolism.

What are the potential benefits of AKG supplements?

AKG is commonly marketed for energy support, exercise recovery, and healthy aging. Evidence in humans is limited and results are mixed for performance-related outcomes.

What is a typical AKG dosage?

Common supplemental amounts are about 1,000–3,000 mg per day. Dosing can vary by product form and individual tolerance.

Is AKG safe for everyone?

Many people tolerate AKG, but safety data are limited for long-term use and for certain medical conditions. People with kidney or liver disease, or those who are pregnant or breastfeeding, should consult a clinician before use.

Does AKG increase longevity in humans?

Some animal research suggests AKG may influence markers related to aging, but robust human evidence for longevity benefits is not established. Human studies are still needed to confirm effects.
