Bonded Amino’s – 2:1 vs 1:1
L-Arginine AKG is actually two ingredients, L-arginine and alpha ketogluterate (AKG). About eight years ago, it was discovered that the absorbability of free form amino acids, like L-arginine are increased when bonded with AKG. The preferred ratio is two parts L-arginine and one part AKG (2:1).
Over time, new tests showed a one to one (1:1) ratio was good on absorbability, but total L-arginine was reduced to nearly insignificant amounts. Before long, 1:1 became the standard. That means if you see L-Arginine AKG….2000mg, there is only 1g of L-arginine.
The 2:1 is now considered a “premium” ingredient yielding 33% more L-arginine with the highest absorbability.
The same is true with many other bonded free form amino acids like L-citrulline malate. A 2:1 ration of Citrulline to malate is premium.
