Advanced Amino Formula Ingredients
What the merchant currently lists in Advanced Amino Formula, how the eight amino acids fit into protein nutrition, and the important histidine question.
The eight listed amino acids
The current merchant page lists isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Three of those—leucine, isoleucine and valine—are branched-chain amino acids.
What is not on that eight-amino-acid list?
Histidine is the important omission to understand. Standard nutritional references classify histidine among the nine essential amino acids for adults. That does not make the product automatically appropriate or inappropriate; it means shoppers should understand what they are actually comparing.
