Iron – iron levels need to be optimal – ferritin 70 + in order for thyroid to functional optimally – low ferritin can mimic some hypothyroid symptoms.
Vitamin B12 should be in upper quarter of range – again lower could mimic hypothyroid symptoms.
Vitamin D – make sure you are getting enough vitamin D from sunlight – if not supplement – but sunlight is always a better source of vitamin D.
With hypothyroidism there are often issues with low stomach acid – so either incorporate betaine pepsin or start using Apple Cider Vinegar or lemon to enhance absorption.
Correct issues with cortisol – by correcting circadian rhythms – lowering inflammation and having good progesterone levels which convert to cortisol.
Look out for re activated Epstein Barr Virus – this is very common for hypothyroid patients
Do 23andme to see if you have MTHFR defect – if you seem to need high doses of T3, what
seems like thyroid resistance, have high iron, high coper/low zinc, hard time getting or keeping
certain nutrients up, high homocysteine etc
Look out for chronic inflammation – this can be determined by too high ferritin and a CRP test.
Check for Candida – this promotes inflammation
Check for gut issues – intolerance to gluten and certain foods
Check blood sugar
Over exposure to mould
H. pylori infection
Factors that increase conversion of FT4 to RT3
Low calorie diet
Nutrients that contribute to proper production of thyroid hormones
Factors that inhibit proper production of thyroid hormones
auto immune disease
Factors that increase conversion of t4 to t3
reduce TH17 and help pro inflammatory conditions with boswellia errata
vitamin A, D, omega 3 helps to prevent nasty pro inflammatory cytokine
Don’t go too low carb as this will affect your T3 levels – make sure you are recycling enough
carbs – have some good carb days
