Dear All, we are having an internal discussion on how to calculate the protein content for labelling purposes based on the European legislation for supplements consisting solely from amino acids and/or other N-containing substances. Can you just sum up the amino acids? Or only the proteinogenic AA? Or do you have to apply the general factor of 6.25? Would you apply the factor to total N or only to N from proteinogenic AA? Or.... Thank you in advance for your inputs.
