Thyroid Medication: T3 and T4
The thyroid hormones thyroxine (T4) and triiodothyronine (T3), are tyrosine-based hormones produced by the thyroid gland primarily responsible for regulation of metabolism. T4 converts to T3, with T3 being 3-4 times stronger than T4. Synthetic T4 (Synthroid) is often prescribed for people diagnosed with hypothyroidism ("sluggish thyroid").
