Douglas Laboratories Thyro-Set is formulated with ingredients that work synergistically to improve thyroid function such as iodine and L-tyrosine which are essential for the production of the thyroid hormones T3 and T4. Thyro-Set is formulated for thyroid support, containing nutrients and herbs that may help in regulating thyroid function. Hypothyroidism, or low thyroid function, is characterized by symptoms such as cold intolerance, depression, hair loss, lack of or low energy, and weight gain. The Ayurvedic adaptogenic herbs Ashwagandha and Coleus forskohlii enhance the production and release the T4 and T3 hormones. Zinc, selenium, and manganese are included in this formula to help further support thyroid health.

As we age, changes occur in many areas of our brain, notably in the prefrontal cortex and hippocampus, that can affect brain volume, neurotransmitter levels, protein and glucose metabolism, blood flow and blood vessel structure. These changes may impact our memory recall, ability to perform tasks and emotional well-being, and compromise overall quality of life. Factors such as genetics, diet, exercise and the environment can all influence cognitive health during later years. Emerging research continues to focus on how we may be able to provide nutritional support during many of the normal, age-related changes we observe in brain function.* *These statements have not been evaluated by the Food and Drug Administration.
