Function
It serves as an essential substrate for the production of dopamine, norepinephrine and epinephrine.
L-Tyrosine supplementation alleviates cognitive decline induced by stressors
Such as sleep deprivation, high pressure and low temperature, and sustains brain performance.
As the primary building block of thyroid hormones, it participates in the regulation of basal metabolic rate,
body temperature maintenance and growth development.
It also facilitates the synthesis of adrenal hormones and enhances the body's stress tolerance.
It is gradually converted into melanin under the catalysis of tyrosinase,
which determines pigmentation in skin, hair and iris.
It also forms a vital physiological defense for skin against UV damage.
As a structural amino acid of proteins, it broadly participates in biological processes including cell proliferation,
differentiation and metabolic regulation.
Application
Sports Nutrition: Widely incorporated into endurance and focus-support sports supplements to
relieve central fatigue caused by high-intensity exercise and high-temperature environments.
Functional Dietary Supplements: Anti-fatigue and mood-support products targeting people
with late-night schedules and high work pressure to help improve mental status.
Food Processing: Used as an amino acid fortifier in special diets.
It also takes part in the Maillard reaction to enhance the flavor and color of baked goods and meat products.
Livestock & Poultry Feed Additive: Added to poultry diets to deepen the pigmentation of egg yolks and poultry skin,
and optimize breed characteristics of special livestock such as black-bone chickens.
Aquaculture: Acts as a nutritional component and feeding attractant in aquafeeds;
Promotes pigmentation on fish body surface and improves feed palatability.
