  • Improves mood, focus, and mental clarity in those with thyroid deficiency
  • Normalizes cholesterol and heart function that are disrupted by hypothyroidism

Potential side effects of T4 include headaches, appetite changes, anxiety, sweating, an irregular heart rate, muscle weakness, hair loss, and insomnia, especially when doses are too high.
