How to Choose a Thyroid Support Formula
A thyroid support formula should be chosen carefully because fatigue, sensitivity to cold, weight fluctuations, mood changes and difficulty concentrating can have many different causes. A professional assessment and blood tests are necessary to determine whether the thyroid gland is functioning normally.
Phytothyro thyroid support by St. Francis Herb Farm is a certified organic tincture designed as a daily tonic to support proper thyroid gland function and overall endocrine and metabolic health. Its formula combines six medicinal herbs: bladderwrack, black walnut, ashwagandha, milky oat seed, guggul and blue flag.
Before choosing this formula, consider the following factors:
- Whether you have been diagnosed with a thyroid disorder.
- The results of your most recent TSH and thyroid hormone tests.
- The use of thyroid replacement therapy, including levothyroxine.
- The use of lithium, sedative medications or other products with sedative properties.
- The presence of hyperthyroidism, which is a contraindication.
- Your preference for a liquid tincture containing alcohol.
- Your ability to take the product three times daily on an empty stomach.
Phytothyro thyroid support should not be used to diagnose a thyroid condition yourself or to replace prescribed thyroid medication. Any change to hormone replacement therapy must be supervised by a health care practitioner.

To Combine With
Phytothyro thyroid support can be incorporated into a comprehensive approach that includes a varied diet, regular sleep, appropriate physical activity and symptom monitoring. It may be helpful to record changes in energy, weight, body temperature, bowel movements, mood and concentration so they can be discussed with a health care practitioner.
