What Are Thyroid Functions, and How Can They Be Naturally Supported?

Question

I recently had a thyroid test, and my doctor mentioned that my levels were slightly off. I never really thought about the thyroid before, but now I’m wondering—what are the thyroid functions, and how can they be naturally supported?

From what I understand, the thyroid controls metabolism, energy levels, and body temperature. But what happens when it becomes overactive (hyperthyroidism) or underactive (hypothyroidism)? How do imbalances in thyroid function affect weight, mood, and overall health?

I also read that iodine, selenium, and certain hormones play a key role in thyroid function. What are the best dietary sources of these nutrients, and are there natural ways to regulate thyroid activity without medication?

Since I prefer natural treatments, I looked into Ayurveda’s approach to thyroid function. Are there Ayurvedic remedies, herbs, or yoga practices that can help maintain thyroid health? I found that Ashwagandha, Guggulu, and Pranayama breathing exercises are often recommended—do these actually help in balancing thyroid hormones?

For those who have dealt with thyroid function issues, what treatments or lifestyle changes helped you the most? Did diet, exercise, or Ayurvedic therapies improve your condition? I’d love to hear real experiences on supporting thyroid function naturally.

The thyroid gland plays a crucial role in regulating metabolism, energy levels, body temperature, and hormone balance. It produces T3 (triiodothyronine) and T4 (thyroxine), which influence digestion, heart rate, and mood. When the thyroid is overactive (hyperthyroidism), symptoms like weight loss, anxiety, and rapid heartbeat can occur. In contrast, an underactive thyroid (hypothyroidism) leads to fatigue, weight gain, and depression.

Essential nutrients like iodine (found in seaweed, dairy, and eggs) and selenium (in Brazil nuts and sunflower seeds) support thyroid hormone production. A balanced diet, stress management, and regular physical activity can help maintain thyroid function naturally. For mild imbalances, some people find relief through lifestyle changes, reducing processed foods, and ensuring proper hydration before resorting to medication.

Ayurveda recommends Ashwagandha (to support energy and stress response), Guggulu (for metabolism), and Pranayama breathing exercises (to balance hormones). Yoga poses like Sarvangasana (shoulder stand) may stimulate thyroid function. Many have reported improvements through diet, herbal remedies, and stress reduction alongside medical guidance. Regular thyroid screenings and a holistic health approach can help maintain thyroid balance naturally.
