Thyax Research:

Acetyl L-Tyrosine, L-tyrosine complex- Tyrosine is required for synthesis of thyroid hormones, and deficiency of phenylalanine and L-tyrosine has been associated with hypothyroidism (1). A form of tyrosine, acetyl-L-tyrosine in combination with phenylalanine has been shown to sufficiently meet the requirement of a certain class of amino acids in adults (2).

  

Zinc (picolinate)- Required for the manufacture of thyroid hormones, zinc is also necessary for overall growth and development (3). Patients with hypothyroidism may have impaired intestinal zinc absorption and lower levels of plasma zinc (4,5). Treatment with zinc improved thyroid function and reduced the incidence of subclinical hypothyroidism in patients with Down syndrome, who have an increased risk of hypothyroidism (6). As well, the addition of zinc supplementation to L-thyroxine therapy in hypothyroid animals improved wound healing (7).

 

L-Phenylalanine - As a precursor to the amino acid tyrosine, phenylalanine plays an important role in thyroid function. Deficiency of phenylalanine and L-tyrosine has been associated with hypothyroidism (1).

 

Iodine (Kelp)- Iodine is a trace element that is required for thyroid hormone synthesis. Deficiency of iodine causes goiter, thyrotoxicosis and developmental disorders in children (8,9). Even mild iodine deficiency can result in hypothyroidism and thyroid disorders, especially in at-risk populations (10). However, excess iodine can actually inhibit thyroid function, and combined dietary and supplemental levels should not exceed 600mcg per day.

Selenium (Sodium Selenite)- Selenium (in the form of selenoproteins) is necessary for the production and conversion of thyroid hormones (11). In addition to iodine supplementation, selenium may mitigate the development of hypothyroidism and may be essential for those with congenital hypothyroidism (12). When combined iodine and selenium deficiencies exist, selenium must always be given with iodine or thyroid hormone (13).

 

Copper (Gluconate), Manganese (citrate), Molybdenum- These trace minerals are closely tied to thyroid function. In animal studies, copper and manganese deficiency and hypothyroidism were worsened when these conditions existed together (14,15).

Vitamin B1 (thiamine HCl), Vitamin B2 (riboflavin), Vitamin B3 (niacin), Vitamin B5 (d-Calcium Pantothenate)- These B vitamins are essential for energy production, mood, nervous system function and wound healing. One of the main complaints of hypothyroidism is fatigue, which is mostly caused by low levels of thyroid hormone but may also be the result of low B vitamin status.

 

Vitamin B6 (Pyridoxine HCL), Vitamin B12 (Cyanocobalamin), Folic Acid- Required for optimal function of the nervous and immune systems, these B vitamins are useful in reducing levels of homocysteine, a detrimental amino acid associated with heart disease. Patients with hypothyroidism have significantly higher plasma levels of homocysteine (16). Supplementation with vitamin B6, B12, and folic acid can lower homocysteine (17).
