I have noticed that all Nitric Oxide products are made up of one of these three Amino Acids (L-Arginine, Arginine Alpha-Ketoglutarate (A-AKG), or Arginine HCl).
Could someone explain the difference between the three and which is the best/most absorption. Thanks.
I am debating which one to get (the prices are different among the 3):
Arginine Alpha-Ketoglutarate (A-AKG)
