L-Arginine and Arginine AKG: A Simple Guide
Arginine is one of the best-known amino acids in the workout world. Here is what it is and what the AKG pairing means.
What arginine is
L-arginine is an amino acid, a building block of protein. Meat, fish, dairy, nuts and seeds supply it, and the body also uses it to make nitric oxide.
Nitric oxide in plain words
Nitric oxide is a small molecule that helps blood vessels relax and widen. That is why arginine often appears in talk about circulation.*
What AKG adds
L-arginine AKG 2:1 joins two parts arginine to one part alpha-ketoglutarate. AKG is a compound the body makes in normal energy chemistry. The official page says this form is more absorbable, but it shows no study on SodaFil itself.
Why two forms
Using plain arginine beside the paired form is a design choice by the maker. Check your bottle label for how much of each is in a capsule.
