What is Alpha Ketoglutarate?

Alpha ketoglutarate (AKG) is a precursor to glutamine and glutamate, which makes it a central fuel in various metabolic processes. Combined with ornithine, an amino acid, alpha ketoglutarate forms a salt (ornithine alpha ketoglutarate, or OKG) that is commonly taken by bodybuilders and athletes to help with muscle growth, endurance, and recovery.

Alpha ketoglutarate is also available with arginine as L-arginine alpha ketoglutarate (AAKG).

Nitrogen booster like I used to take

I use another product for years that contained these chemicals in capsul form. It was expensive and then impossible to find. It helped with weight training. I recently read about how it boosts longevity in some studies so looked up this prouduct. It made me feel better with the first little teaspoon dose! Just feels like I have more energy in mind and body.

Great Product

I am not a body builder. I'm 82 yr old and have been using this product every morning in my drink of Honey and Vinegar plus apple juice. I have tasted the powder and it has a pleasant taste. I also take a regimen of vitamins, minerals and herbs every day. I am trying to maintain the body and health that I have as long as I can.
