The thyroid gland is responsible for normal thyroid function and hormone production, which are essential to a person’s overall health. While bad diet and stress can cause imbalances in the body, poor thyroid glandular health is actually responsible for 70% of all cases of hypothyroidism. In fact, when you opt for an herbal approach like a liver glandular supplement to help improve your thyroid health, it also improves your overall health by supporting many other systems in the body.
