L-Tyrosine

Healthy Neurotransmitter Metabolism and Thyroid Function*

A synergistic blend of L-tyrosine and vitamin C to support healthy stress responses, cognitive health, energy production, and healthy aging.*

Designs for Health’s L-Tyrosine features 1.2 g of L-tyrosine and 100 mg of vitamin C (as ascorbic acid) per 2-capsule serving.

• Supports cognitive health*
• Supports a healthy stress response*
• Supports healthy aging*
• Supports healthy thyroid function*

Recommended Use: Take 2 capsules per day on an empty stomach or as directed by your health-care practitioner.

Some individuals may require a greater intake of tyrosine than what is typically obtained from the diet*

Tyrosine is a conditionally essential amino acid required for the optimal function of numerous biochemical pathways and physiological processes.* It is the building block for thyroid hormones, melanin pigment, and the neurotransmitters dopamine, epinephrine, and norepinephrine. As such, adequate intake of tyrosine may support healthy energy production, stress responses, healthy aging, metabolism, and cognitive health.* Vitamin C is a required cofactor for neurotransmitter synthesis from tyrosine.

What This Product Is

L-Tyrosine features 1.2 g of L-tyrosine and 100 mg of vitamin C (as ascorbic acid) per 2-capsule serving. Tyrosine is a conditionally essential amino acid required for the optimal function of numerous biochemical pathways and physiological processes. It is the building block for thyroid hormones, melanin pigment, and the neurotransmitters dopamine, epinephrine, and norepinephrine. As such, adequate intake of tyrosine may support healthy energy levels, stress responses, healthy aging, metabolism, and cognitive health.*

Dopamine is involved in memory, learning, and reward processes and plays an important role in healthy aging. Norepinephrine and epinephrine help the body cope with stress. When individuals are experiencing stress or cognitively challenging tasks, the body may become temporarily depleted in dopamine, norepinephrine, and epinephrine, which may leave a person feeling exhausted or overwhelmed. Since tyrosine is a building block to these neurotransmitters, tyrosine may help support a healthy stress response, sustained energy levels, mood, cognitive health, and mental flexibility. Vitamin C is a required cofactor for neurotransmitter synthesis from tyrosine.*

Mechanism of Action

Tyrosine for Neurotransmitter and Thyroid Hormone Synthesis*

L-Tyrosine (1.2 g) is the building block for thyroid hormones, melanin pigment, and the neurotransmitters dopamine, epinephrine, and norepinephrine. During challenging or stressful situations, tyrosine may help support the body's ability to maintain adequate neurotransmitter levels, supporting cognitive performance, mood, and the ability to tolerate tasks requiring challenging thinking or fine motor skills.* Although the body can synthesize tyrosine internally, synthesis capacity declines with age, and certain amino acids compete with tyrosine for absorption.*

Vitamin C as Neurotransmitter Synthesis Cofactor

Vitamin C (100 mg as ascorbic acid) is a required cofactor for neurotransmitter synthesis from tyrosine. The inclusion of vitamin C ensures the body can efficiently convert tyrosine into dopamine, norepinephrine, and epinephrine. Some individuals may have a need for a greater intake of tyrosine than what is typically obtained from the diet, making isolated tyrosine supplementation with its required cofactor beneficial for optimizing neurotransmitter production.*

Applications

  • Individuals seeking cognitive health and mental flexibility support*
  • Those wanting healthy stress response support during demanding situations*
  • Individuals needing sustained energy levels and healthy aging support*
  • Those seeking thyroid hormone and neurotransmitter production support*
  • Individuals whose tyrosine synthesis may be declining with age*

Product Questions

Why should L-Tyrosine be taken on an empty stomach?

Certain amino acids compete with tyrosine for absorption. Taking L-Tyrosine on an empty stomach helps optimize tyrosine intake by reducing competition from other amino acids present in food. This allows for more efficient absorption and utilization of tyrosine for neurotransmitter and thyroid hormone synthesis.*

Why is vitamin C included with L-Tyrosine?

Vitamin C is a required cofactor for the synthesis of neurotransmitters from tyrosine. Without adequate vitamin C, the body cannot efficiently convert tyrosine into dopamine, norepinephrine, and epinephrine. Including 100 mg of vitamin C ensures that the cofactor needed for optimal neurotransmitter production is available alongside the amino acid building block.*

Who may benefit most from L-Tyrosine?

Individuals experiencing stress or cognitively challenging tasks who need neurotransmitter support, those seeking cognitive health, mental flexibility, and sustained energy levels, older individuals whose tyrosine synthesis capacity may be declining with age, and anyone wanting thyroid hormone and neurotransmitter production support with the required vitamin C cofactor.*
