Your pituitary gland, found at the base of the brain, produces and secrets thyroid-stimulating hormone that stimulates your thyroid gland and helps regulate body's growth, development and metabolic function. Your thyroid gland is shaped like a butterfly and is located in the front part of your lower neck. The amino acid tyrosine plays an important role in regulating your thyroid function and may also be used as an adjunct in the treatment of hypothyroidism. Speak to your doctor before taking tyrosine supplements for the treatment of hypothyroidism.
Hypothyroidism
The thyroid gland produces two important hormones called tetraiodothyronine, or T4, and triiodothyronine, or T3. These hormones may affect everything from appetite to body temperature. Hypothyroidism occurs when your thyroid gland does not produce enough of these thyroid hormones. People with hypothyroidism may have symptoms such as constipation, fatigue, weight gain and depression.
About Tyrosine
Tyrosine is the nonessential amino acid found in meat, dairy products, soy products, beans, bananas, pumpkin seeds and sesame seeds. In your body, tyrosine is used as a starting material for the production of thyroid hormone. Low levels of tyrosine have been associated with underactive thyroid, according to the University of Maryland Medical Center.
Dosage
As a dietary supplement, L-tyrosine is available in the form of capsules and tablets. The University of Maryland Medical Center suggests that intake of tyrosine at a dosage of 500 mg two to three times a day may help prevent or treat symptoms associated with hypothyroidism. A good diet, along with regular exercise, may increase the effectiveness of tyrosine supplements to help combat hypothyroidism.
Safety
Tyrosine is generally safe to use, according to Swedish Online Health library. However, intake of higher-than-recommended dosage of tyrosine may cause adverse effects such as nausea, vomiting, diarrhea and nervousness. Intake of tyrosine supplements in combination with prescription thyroid medication may raise levels of thyroid hormone too high in your body. Consult your doctor before taking tyrosine supplements along with prescription thyroid medication.
