L-Tyrosine by Designs for Health


L-Tyrosine (120 capsules) is a non-essential amino acid that the body synthesizes from phenylalanine. Tyrosine acts as a precursor for the production of dopamine, which is then converted to norepinephrine and ultimately to epinephrine. These neurotransmitters play an essential role in various bodily functions such as mood regulation, stress response, and cognitive health

Our popular tyrosine powder is now available in a convenient 1.2 g tablet, along with 100 mg of vitamin C as a cofactor for neurotransmitter production. Tyrosine is a conditionally essential amino acid synthesized in the body from the essential amino acid phenylalanine, and is required for the optimal function of many biochemical pathways and other bodily processes.

Tyrosine is a vital nutrient that acts as a building block for several essential compounds such as thyroid hormones, melanin pigment, and neurotransmitters like dopamine, epinephrine, and norepinephrine. Adequate intake of tyrosine supports healthy energy levels, stress responses, cognitive health, metabolism, and healthy aging. Vitamin C is required for the synthesis of neurotransmitters from tyrosine.

Dopamine plays a vital role in memory, learning, and reward processes and contributes to healthy aging. Norepinephrine and epinephrine help the body cope with stress. During stressful or mentally challenging situations, the body may become temporarily depleted of dopamine, norepinephrine, and epinephrine. This can leave a person feeling exhausted or overwhelmed. As tyrosine is a crucial building block for these neurotransmitters, it can help support a healthy stress response, sustained energy levels, mood, cognitive health, and mental flexibility. Tyrosine may also assist in multitasking and improve the body’s ability to tolerate tasks that require challenging thinking or fine motor skills.

Although the body can synthesize tyrosine, the capacity for tyrosine synthesis declines with age. Some individuals may have a greater need for tyrosine intake than what is typically obtained from their diet. Furthermore, certain amino acids in food compete with tyrosine for absorption, making it challenging to obtain enough tyrosine from food alone. Therefore, individuals looking to optimize their tyrosine levels may benefit from isolated tyrosine supplementation.

The typical dietary amount provided by a 3 oz. portion of animal protein is 0.3-1 g of tyrosine. Tyrosine is the precursor amino acid from which the body makes dopamine (with vitamin B6 as a cofactor), which is then converted to norepinephrine (with vitamin C as a cofactor) and then to epinephrine (with SAMe as a cofactor). Tyrosine competes for uptake with other large neutral amino acids, so in order to maximize absorption from the supplemented tyrosine into various tissues (such as brain, adrenals, nerves), it should be taken on an empty stomach, or two hours away from a protein-containing meal.
