Thyroid – Understanding the Shield Within

Updated: Jul 9

Your Master Gland At the front of your neck is your thyroid, shield-like shaped gland that secretes two hormones, T4 (thyroxine) and T3 (triiodothyronine). These hormones influence the metabolic processes throughout your entire body; instructing your heart to beat, your lungs to breathe, your digestion to absorb food and your cells to convert that food into energy. For something so small, your thyroid plays a large role in your overall vitality!
