THYREX is a dietary supplement which helps improve the function of the thyroid gland in a completely natural way. An insufficient functioning of the thyroid gland is one of the primary causes of quality-of-life problems like energy problems, mental imbalance and obesity.
THYREX is a dietary supplement which helps improve the function of the thyroid gland in a completely natural way. THYREX can be used for the treatment of subclinical hypothyroidism in monotherapy as well as for the treatment of overt hypothyroidism in combination with replacement therapy.
Dysfunction of the thyroid gland is one of the main causes of quality of life issues, such as lack of energy, mental imbalance and obesity. Mild forms of thyroid dysfunction can be treated easily with the help of natural stimulation and do not necessarily require replacement therapy for optimal treatment. In severe forms of thyroid dysfunction a combination of replacement therapy and stimulation is the
best guarantee for an optimal quality of life.
THYREX is a dietary supplement that supports the thyroid optimally in a completely natural way. Thyrex consists of a combination of L-Tyrosine and Iodine, the basic ingredients of our thyroid hormones, supplemented with Withania Somnifera, an adaptogen which has been scientifically proven to stimulate thyroid function, as well as Selenium, Zinc and Vitamin B1, which are the three main cofactors required
for optimal thyroid hormone replacement therapy.
