Amino acids the body cannot synthesize
Human Histidine Needs
Amino acid required for growth, tissue repair, and production of histamine and hemoglobin.
Human Isoleucine Needs
Branched-chain amino acid involved in muscle metabolism, immune regulation, and energy production.
Human Leucine Needs
Branched-chain amino acid that stimulates muscle protein synthesis and regulates metabolic signaling pathways.
Human Lysine Needs
Amino acid necessary for protein synthesis, calcium absorption, hormone production, and immune function.
Human Methionine Needs
Sulfur-containing amino acid used in methylation processes and as a precursor to cysteine and other important biomolecules.
Human Phenylalanine Needs
Aromatic amino acid used to synthesize tyrosine and important neurotransmitters such as dopamine and norepinephrine.
Human Threonine Needs
Amino acid important for protein structure, immune function, and synthesis of collagen and elastin.
Human Tryptophan Needs
Amino acid used in the synthesis of serotonin, melatonin, and niacin.
Human Valine Needs
Branched-chain amino acid supporting muscle metabolism, tissue repair, and energy production.
