The thyroid is a butterfly-shaped gland crucial for hormone production affecting metabolism, heart rate, and more. Signs of thyroid issues include weight changes, irregular heartbeat, and temperature sensitivity. You can live without a thyroid with hormone therapy. Key hormones include T3, T4, RT3, and calcitonin. Iodine is essential but must be balanced. Thyroid disease affects 20M+ Americans—main types include hypothyroidism and hyperthyroidism. Women are especially at risk

Estrogen Dominance isn’t just about high estrogen — it’s the imbalance between estrogen and progesterone. Even low estrogen can be problematic if progesterone is lower. Estrogen dominance disrupts thyroid function and metabolism. To rebalance: support progesterone, block aromatase, detox stored estrogen, and reduce estrogen activity. Carbs matter — long-term low-carb can worsen aromatase. A balanced diet with liver-loving, estrogen-clearing foods is key to hormone health.
