Handy way to top up your L-arginine levels
Amino acids are the building blocks of protein. L-arginine is an essential amino acid found in seafood, watermelon, nuts and meat. We also produce L-arginine in the liver but use it all up preventing the concentration of arginine in the blood from reaching significant levels.
