T4

T4 (Levothyroxine Sodium) is a prohormone thyroid medication that converts into T3 in the body, supporting baseline metabolic function and energy regulation. It provides a more gradual and stable thyroid effect compared to direct T3 use.

Common dosing:
• 25–50 mcg per day
• 50–100 mcg per day (advanced use)

Dosing is typically adjusted based on individual response.
