Thyroid

A holistic guide to understanding, supporting and repairing your thyroid.

Understanding

Understanding Your Thyroid

Your thyroid is a butterfly-shaped gland in your neck. It's the body's thermostat and gas pedal—controlling metabolism, energy, temperature, mood, and weight. It needs iodine, selenium, zinc, and tyrosine to make hormones. Most thyroid problems are autoimmune (Hashimoto's or Graves') triggered by gut issues, stress, and environmental toxins.

Quick Reference

Quick Reference Guide

  • Get a full thyroid panel tested (TSH, Free T3, Free T4, Reverse T3, antibodies).
  • Eat sea vegetables for natural iodine.
  • Manage stress—cortisol blocks thyroid conversion.
  • Avoid fluoride and chlorine when possible (they compete with iodine).
  • Sleep in a cool, dark room.

Hyperthyroid

  • Weight loss despite eating
  • Anxiety and tremors
  • Heat intolerance
  • Rapid heartbeat
  • Bulging eyes
  • Frequent bowel movements

Root Causes

Root Causes

  • Autoimmune attack (Hashimoto's)
  • Iodine deficiency or excess
  • Selenium deficiency
  • Chronic stress and high cortisol
  • Gut dysbiosis and leaky gut
  • Environmental toxins (fluoride, bromide, chlorine)
  • Estrogen dominance
  • Liver congestion (poor T4 to T3 conversion)

Remedies

Natural Remedies

Ashwagandha

Adaptogen that supports thyroid conversion. Source: Banyan Botanicals, Himalaya.

Selenium-rich Brazil Nuts

2–3 nuts daily provides the selenium your thyroid needs.

Sea Vegetables

Kelp, dulse, nori for natural iodine (use cautiously if Hashimoto's).

Castor Oil Packs

Apply over the neck/throat area to increase circulation.

Reduce Stress

Meditation and sleep are thyroid medicine.

Vitamins

Vitamins & Supplements

Selenium (200mcg)

Essential for T4 to T3 conversion.

Thorne, Pure Encapsulations

Zinc (15–30mg)

Needed for thyroid hormone production.

Thorne

Iodine (only if deficient)

Potassium iodide or sea kelp. Can worsen Hashimoto's—test first.

Life Extension

L-Tyrosine

Amino acid building block of thyroid hormone.

Jarrow, Pure Encapsulations

Vitamin D3

Low levels linked to autoimmune thyroid.

Thorne

Myo-Inositol

Helps balance thyroid antibodies and hormones.

Foods

Healing Foods

Brazil Nuts

2–3 daily for selenium.

Seafood & Sea Veggies

Natural iodine and zinc.

Eggs

Iodine, selenium, and tyrosine.

Berries

Antioxidants reduce thyroid inflammation.

Leafy Greens

Rich in minerals (rotate for oxalate variety).

Bone Broth

Glycine supports conversion enzymes.

Avoid: excessive raw goitrogens (soy, raw cruciferous veggies) if iodine deficient.

Movement

Movement & Exercise

Walking & Yoga

Gentle daily movement—over-exercising stresses the thyroid.

Strength Training

Builds metabolism-supporting muscle.

Avoid Chronic Cardio

Long-distance running can suppress thyroid function.

Swimming

Gentle, full-body, no impact.

FAQs

FAQs

Q: Why does my doctor say my thyroid is "normal" but I feel terrible?

A: Most doctors only test TSH. You need Free T3, Free T4, Reverse T3, and antibodies to see the full picture.

Q: Can I heal Hashimoto's naturally?

A: You can put it into remission by healing the gut, reducing antibodies, and supporting conversion. Medication may still be needed.

Q: Is iodine good or bad?

A: It depends. Deficiency causes goiter, but excess can trigger autoimmune flares. Test before supplementing.

Did You Know

Did You Know?

Your thyroid is the only organ that absorbs iodine—it literally pulls iodine from your blood to make hormones that control every cell's energy level.

Sound Healing

Sound Healing — 492.8 Hz

492.8 Hz is the thyroid frequency. Pair with 741 Hz for detox support.

Fasting

Fasting Connection

Fasting can temporarily lower T3 (active hormone) to conserve energy. For hypothyroid individuals, shorter fasts (14–16 hours) are safer than prolonged fasting.
