What Is the Difference in L-Lysine & L-Tyrosine?

L-lysine and L-tyrosine are amino acids with distinctly different functions in the body. Primarily, lysine boosts the immune system while tyrosine affects mental health and hormone levels.

  1. Lysine and Herpes

    • Even stubbornly persistent herpes viruses often respond to lysine, reducing the pain and suffering that accompanies cold sores, shingles or genital herpes.

    Tissue and Bones

    • Lysine helps rebuild and repair tissue after injury or surgery, and it helps stave off osteoporosis by assisting with the uptake of calcium.

    Tyrosine and Hormones

    • Tyrosine is the building block of dopamine, a neurotransmitter responsible for a person̵7;s ambition and drive, while conversely creating a sense of satisfaction with moderation. This amino acid also increases the body̵7;s supply of adrenaline and thyroid hormones.

    Tyrosine and Appetite

    • More dopamine means less appetite. Not only does tyrosine suppress cravings for sugary foods, but, according to wellness reference manual ̶0;Healthy Healing,̶1; it also helps reduce body fat.

    Nonessential versus Essential

    • Tyrosine is regarded as a nonessential amino acid because the body can make it from other amino acids. Lysine is an essential amino acid, which means it must be supplied from protein in the diet.
