What IS Doctor's Best Tyrosine? Doctor's Best Tyrosine is a
conditionally essential amino that is a precursor to the
catecholamine transmitters, dopamine, epinephrine, and
norepinephrine. These are vital messengers for the brain and the
body's other nerve networks. The thyroid gland also needs
Tyrosine to make the vital hormone thyroxine. Doctor's Best
l-tyrosine supplies the pure l-form of Tyrosine, an amino
that has many important functions in the body. Tyrosine or
4-hydroxyphenylalanine, is one of the 22 amino s that are
used by cells to synthesize proteins. How does it work? 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. In dopaminergic cells in the
brain, l-tyrosine is converted to L-Dopa by the enzyme Tyrosine
hydroxylase, then to 3, 4-dihydroxyphenylalanine (dopamine), a
precursor used both for the synthesis of catecholamine's
messengers (dopamine, epinephrine, and norepinephrine) and for
making the pigment melanin. Increasing the levels of l-tyrosine
in the brain may help to alleviate the neurological decline of
catecholamine's that are typically decreased in States of
dementia. Thus, catecholamine's may act as antioxidants in the
brain and be neuroprotective. L-tyrosine helps prevent a decline
in cognitive function in response to physical stress. Melanin,
the body's major pigment that contributes to skin, hair, and eye
colour, 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. The melanin deposited in skin cells forms
a barrier-known as supranuclear caps-to shield our from UV
radiation. Precursor for the nerve messengers dopamine,
norepinephrine, and epinephrine (adrenaline) the catecholamine's
dopamine, epinephrine (adrenaline), and norepinephrine
(noradrenaline) are integral to central nervous system functions
such as , emotion, memory, movement, and Regulation of
glands that secrete hormones into the blood. Their production can
be limited by the a of Tyrosine available to the enzyme that
converts Tyrosine to 3, 4-dihydroxyphenylalanine. Adrenaline and
noradrenaline are released from the adrenal gland, often in
response to stress, and are part of a broad-based physiologic
response that can increase the c rate of cells through
adjusting a number of bio processes. Adrenaline and
noradrenaline are also used to regulate ent sm,
including to increase stored energy utilization by breaking down
glycogen into simpler sugars and releasing ty s from
triglycerides. Stress & mood. Tyrosine at high doses has been
shown to significantly promote positive behaviour characteristics
(like mood) and a superior response to stress in humans exposed
to environmental or cardiovascular stressors. Precursor for
thyroxine production by the thyroid gland the thyroid secretes
two very important hormones, triiodothyronine (T3) and thyroxine
(T4). these help regulate our c rate, which closely
approximates how intensely we manage our life processes. Hormones
T3 and T4 also regulate oxygen use, cellular sm, and the
body's overall growth and development. One of the several steps
leading to the formation of thyroid hormones requires that
enzymes attach iodine to Tyrosine.
