Supplements That Support Thyroid Function and Weight Balance

How Thyroid Hormones Affect Weight

The thyroid gland produces two primary hormones — T3 (triiodothyronine) and T4 (thyroxine). These regulate basal metabolic rate, influencing how many calories your body burns at rest.

• Low T3 = slower metabolism
• Hypothyroidism can cause fatigue and fat gain
• Elevated TSH often indicates thyroid underperformance

1. Iodine: The Building Block of Thyroid Hormones

Iodine is essential for the synthesis of T3 and T4. Your body doesn’t produce iodine — it must come from diet or supplements.

• Sources: Seaweed, iodized salt, eggs, dairy
• Too much iodine can also harm — aim for moderate intake (~150 mcg/day)

2. Selenium: The Antioxidant Shield

Selenium helps convert T4 to the active T3 form and protects thyroid cells from oxidative damage.

• Improves thyroid hormone metabolism
• Reduces Hashimoto’s thyroiditis inflammation (autoimmune)
• Supports fertility and immunity

3. Zinc: For Hormonal Communication

Zinc plays a key role in thyroid hormone production and immune health.

• Low zinc = low T3 and elevated reverse T3
• Boosts leptin sensitivity and supports appetite regulation

4. Ashwagandha: The Adaptogen for Stress and Thyroid

This Ayurvedic herb has shown benefits in both managing cortisol and improving thyroid levels.

• Supports TSH and T3 balance
• Reduces anxiety and improves sleep
• Shown to improve energy and reduce fatigue

5. Vitamin D: The Immunity–Thyroid Link

Low vitamin D levels are common in people with thyroid dysfunction, especially autoimmune thyroiditis.

• Modulates immune activity in Hashimoto’s
• Improves mood and reduces fatigue
• Supports calcium metabolism (critical if on thyroid meds)

6. L-Tyrosine: The Precursor for T3 and T4

Tyrosine is an amino acid required for the synthesis of thyroid hormones, when paired with iodine.

• Used by the thyroid to produce T3/T4
• Also supports focus and neurotransmitter production
• Helpful for brain fog and fatigue

7. B-Complex Vitamins: Energy and Hormone Support

B-vitamins — especially B12, B6, and folate — play a role in energy metabolism, red blood cell formation, and neurological health.

• B12 deficiency is common in hypothyroidism
• B6 helps regulate mood and reduces PMS
• Folate supports detox and hormonal balance

Lifestyle Tips to Support Thyroid Naturally

Supplements help — but they work best with supportive lifestyle habits:

• Avoid excessive soy and gluten (may impact absorption)
• Reduce chronic stress (cortisol interferes with T3 conversion)
• Prioritize 7–8 hours of sleep
• Strength train 3–4x per week to boost metabolism
• Get sunlight exposure for vitamin D
