Doctor's Best L-Tyrosine supplies the pure L-form of tyrosine, an amino acid that has many important functions in the body. Tyrosine is perhaps best known for its crucial role in the production of certain substances that have vital messenger actions in the brain and the rest of the nervous system (as nerve transmitters) as well as elsewhere in the body. Tyrosine also can have specialized roles even when incorporated into proteins tyrosine kinase enzymes, for example, are fundamentally important for diverse signaling and regulatory functions.
Tyrosine can be converted to 3,4-dihydroxyphenylalanine, a precursor used both for the synthesis of catecholamine messengers (dopamine, epinephrine, and norepinephrine) and for making the pigment melanin.2,3 Although L-tyrosine can be formed within the body from the essential amino acid L-phenylalanine, this conversion process is likely insufficient to fully meet the body’s need for L-tyrosine, even under normal conditions. This means the body may require extra tyrosine from the diet in special circumstances.
Why take Doctor's Best L-Tyrosine?
Melanin, the body's major pigment that contributes to skin, hair, and eye color, is synthesized from L-tyrosine through a series of steps that begin with conversion to 3,4-dihydroxyphenylalanine. Melanin is very important for regulating the skin's exposure to ultraviolet (UV) light.
When the skin is exposed to UV light, enzymatic activity escalates within melanosomes (cellular factories that produce and transport melanin), resulting in increased melanin within the skin so that more UV light can be absorbed. This is the biological basis of the body's tanned appearance. The melanin deposited in skin cells forms a barrier known as supranuclear caps to shield our DNA from UV radiation.
