Natural Factors, L-Tyrosine, 250g

Natural Factors L-Tyrosine 5 g provides a higher dose of this free-form amino acid in a convenient powdered form. L-tyrosine helps decrease cognitive fatigue resulting from physically stressful situations, such as extended wakefulness, exposure to cold, and excessive noise.

L-tyrosine is a fundamental component of proteins and a precursor for several important compounds in the body, including thyroid hormones, the pigment melanin, and neurotransmitters involved in stress response, such as dopamine, norepinephrine, and epinephrine.

L-tyrosine is synthesized internally from the amino acid phenylalanine, but research suggests that this production decreases during periods of stress. While L-tyrosine is naturally present in protein-rich foods like meat, fish, dairy, and nuts, it is most effective when consumed directly in its free form.

Supplementing with L-tyrosine may benefit people at risk of fatigue or overstimulation from physical stress, including individuals with irregular work and sleep schedules, athletes involved in strenuous training, and professionals working in physically or mentally demanding environments.

Each scoop of this neutral-tasting, vegan powder contains 5 g of L-tyrosine, providing 10 g per two daily doses. This is a high-potency L-tyrosine supplement formulated for people experiencing high levels of acute stress. It is non-GMO, derived from vegan sources, and contains no flavours, sweeteners, or fillers.
