Your immune system protects your body from foreign pathogens that could potentially cause illness and disease. Three amino acids that support a stronger immune system are glutamine, cysteine and arginine. These biomolecules are important in regulating the immune response.Glutamine deficiency causes reduced B cell differentiation and reduced T cell proliferation in the body. Make sure you receive adequate amounts of the amino acid to maintain optimal lymphocytic proliferation, cytokine production and macrophage production.Arginine helps the body sustain proper activation of B cells and antibody production. Cysteine fosters a stronger immune system because it serves as the precursor to glutathione, which enables T cell activation and proliferation.Next
