Arginine alpha-ketoglutarate, used to raise nitric oxide for pumps
We rank A-AKG (Arginine Alpha-Ketoglutarate) by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
A-AKG is the short name for Arginine Alpha-Ketoglutarate. This is a supplement created by combining two different molecules: Arginine, which is an amino acid (a building block of protein), and Alpha-Ketoglutarate, which is an organic acid that helps the body produce energy.
It is primarily used to increase the levels of nitric oxide in the body. Nitric oxide is a gas that relaxes the inner muscles of your blood vessels, causing them to widen. This process improves blood flow, which athletes often refer to as the pump because it makes muscles feel fuller and tighter during a workout.
To produce this supplement, manufacturers combine the amino acid Arginine with Alpha-Ketoglutarate. They react these two components together to create a stable salt. Once this chemical bond is formed, the resulting substance is processed into a fine powder, which is then either sold as is or packed into capsules.
This ingredient sits in a mid-range price bracket. This is because the raw materials are not as cheap as basic amino acids, but the manufacturing process is straightforward and there is plenty of competition among supplement brands to keep costs from becoming too high.
