L-Tyrosine

L-tyrosine is an amino acid precursor to epinephrine, a natural chemical in the body that allows fat to be mobilized and burned as energy. L-tyrosine is also a precursor to thyroid hormones, which maintain proper metabolic rate. L-tyrosine supports fat loss efforts, especially in combination with the effects on metabolism of citrus aurantium and caffeine. Mild stress and anxiety may be relieved by L-tyrosine, as well as fatigue.*
