L-Tyrosine – 100 Caps | Amino Acid for Thyroid & Cognitive Support

L-Tyrosine supplement provides a high-quality source of the amino acid tyrosine, which plays an important role in the production of thyroid hormones and neurotransmitters. This formula is ideal for individuals seeking support for mental performance, stress response and healthy thyroid function.

What Is L-Tyrosine?

L-Tyrosine is a non-essential amino acid, meaning the body can produce it from phenylalanine. However, internal production is limited, and dietary intake may be beneficial—especially during periods of stress, increased mental workload or low protein intake. Tyrosine naturally occurs in foods such as bananas, avocados, eggs, meat and dairy products.

Supports Thyroid Hormone Production

L-Tyrosine is a precursor in the synthesis of key thyroid hormones, including thyroxine (T4). These hormones rely heavily on iodine—approximately 65% of their structure is iodine. In regions with low dietary iodine intake, thyroid imbalances are more common. Using an L-Tyrosine supplement may support thyroid function, especially when combined with sufficient iodine intake.

Cognitive & Stress Support

Tyrosine contributes to the production of neurotransmitters such as dopamine, norepinephrine and epinephrine. These transmitters influence mood, motivation, focus and the body’s stress response. Supplementing with L-tyrosine may help support concentration and cognitive performance during demanding situations.
