Product Overview


  • Dietary Supplement
  • Athletic Series
  • Potassium & Magnesium Alpha-Ketoglutarate

K-Mag KG is a combination of the essential minerals potassium and magnesium with alpha-ketoglutaric acid (AKG). Potassium, magnesium, and AKG all have important roles in the Krebs cycle, the body's main energy production system. Potassium is important for muscle strength and glycogen formation, while magnesium helps store body energy as magnesium ATP (adenosine triphosphate, the body's chief energy molecule). AKG combines with the harmful ammonia generated by intense muscle activity to create glutamine, an important energy fuel.

Suggested Use

1 to 2 tablets daily with a meal.

Saving my brain

Posted by iHerb Customer on Feb 21, 2011 | Verified Purchase

I have chronic Lyme disease, and many of the protocols that kill off Lyme and its co-infections produce nasty by-products: especially ammonia in the brain. This can cause irritability, negativity, anxiety and brain-fog. K-Mag-Kg is a fantastic ammonia mopper, which has greatly helped me as well as others in my Lyme groups. I take two daily and keep extra on hand always in case of extra die-off symptoms. Great stuff!

Thanks for your feedback!

Seems effective

Posted by iHerb Customer on Nov 09, 2010 | Verified Purchase

I had a job finding a reasonably pure AKG supplement having tested very low on a metabolic acid profile. I was concerned that I might not tolerate this due to fillers/binders, but - two weeks in - it seems fine. I think I have noticed a slight increase in energy/stamina, though this is only part of my personal picture, so I can't say for sure yet. Five stars, because I'm pretty sure it's the real McCoy.
