Thriving with optimal thyroid hormones (T3, T4, TSH)

  • Thyroid hormones are made by the thyroid at the base of the neck. 
  • Production is 90% T4 Thyroxine and only 10% active T3 triiodothyronine
  • The pituitary gland in the brain starts the process by releasing TSH (thyroid stimulating hormone). 
  • Some T4 is then converted into the more bioactive T3 (3-5 times as active) 
  • T3 helps every cell in the body produce the energy molecule ATP 
  • Thyroid hormones boost metabolic rate, increases blood circulation which augments nutrients, oxygen, water, and hormones to cells all over the body.
  • Thyroid hormones help keep the body warm and muscles and joints healthy and pain-free. 
  • Protects the brain, heart, kidneys, digestive and immune system. 
  • Increases fat burning 
  • Helps eliminates cholesterol which helps open up the arteries and improves blood pressure.

  • Difficulty losing fat 
  • Morning fatigue

Improving levels of thyroid hormones 

  • Consume a fiber-rich diet as fibers attract heavy metals, mercury toxins, and help flush them out 
  • A diet rich in fruit nourishes the Thyroid. Dr. Hertoghe stated he was able to lower his dosage of thyroid hormones after increasing fruit consumption 
  • Address estrogen dominance as excess estrogen interferes with thyroid function (Dr. Nick Delgado) 
  • Eat 2-3 brazil nuts daily to improve selenium levels. No more than 200mcg per day as too much lowers thyroid function. 
  • Add a teaspoon of kelp to meals to increase iodine levels 
  • Consume hemp seeds and pumpkin seeds to acquire zinc 
  • Take Udo’s oil or milled flaxseeds, chia seeds, and hemp seeds for essential fatty acids. 
  • Take 1-3 grams of the amino acid tyrosine to boost sluggish thyroid hormone production. 
  • Ashwagandha converts T4 into the more active T 3 at 500mg per day 
  • For an overactive thyroid use lemon balm extract to regulate levels.
