ʟ‑Tyrosine is an amino acid which helps optimize weight loss, mood, libido, efficiency at work, and peripheral circulation—thus helping to reduce cold limbs.

ʟ‑Tyrosine is a nonessential amino acid (protein building block) that the body synthesizes from the amino acid phenylalanine. Tyrosine is important for the structure of almost all proteins in the body.

ʟ‑Tyrosine, through its effect on neurotransmitters, may affect several health conditions, including mood disorders. Preliminary findings indicate a beneficial effect of tyrosine, along with other amino acids, in people affected by dementia, including Alzheimer’s disease. Due to its role as a precursor to norepinephrine and epinephrine (two of the body’s main stress-related hormones), tyrosine may also ease the adverse effects of environmental, psychosocial, and physical stress.

ʟ‑Tyrosine is a precursor to thyroxine, a primary thyroid hormone. Tyrosine is a precursor to many neurotransmitters, such as adrenaline (also called epinephrine); noradrenaline (also called norepinephrine); and ʟ‑dopamine, which is a precursor to dopamine. These neurotransmitters are crucial to brain functions. ʟ‑Tyrosine also supports libido and protects from ultraviolet rays.

ʟ‑Tyrosine is used to treat conditions such as mood disorder, poor coping ability, fatigue, low sex drive, low metabolism, and drug abuse (when combined with tryptophan). It can also improve endurance under stress and is effective as an appetite suppressant. When taken properly, ʟ‑tyrosinecan assist a sluggish thyroid and aid the dieter in losing excess, unwanted pounds.

ʟ‑Tyrosine is converted by skin cells into melanin, the dark pigment that protects against the harmful effects of ultraviolet light. Thyroid hormones, which have a role in almost every process in the body, also contain tyrosine as part of their structure.
