Thyroid Hormone Replacement
Levothyroxine · Liothyronine (T3) · Desiccated thyroid
Mechanism
Replaces or supplements thyroid hormone (T4/T3) when endogenous production is insufficient.
Environmental footprint
Restores metabolic rate when dosed correctly. Over-replacement strains heart and bone. Under-replacement leaves symptoms unresolved.
What the evidence shows
Essential for hypothyroidism. Levothyroxine is standard of care. Timing, food interactions, and dose adjustment require monitoring. Overtreatment causes hyperthyroid symptoms.
