what you need to know about ferritin (your personal iron reservoir!) if you have a thyroid condition:
🩸suboptimal ferritin can produce symptoms like hair loss and fatigue that are often blamed on the thyroid
🩸GPs often ignore the importance of ferritin and rarely flag it as abnormal.. even at levels below 30 ng/ml (and we really want to be aiming for 70!)
🩸the GP prescribed and store bought iron supplements lead to a lot of digestive issues
🩸Adequate ferritin level is crucial for thyroid hormone conversion
🩸High daily iron supplementation can fuel the inflammation and still fail to raise the ferritin levels (esp when the transport is poor)
🩸Heavy periods contribute to the issue
🩸Hashimoto’s with high inflammation levels, combined with low digestion/ stomach acid production is the root cause of low ferritin for most with Hashi
you can apply the tips I shared above and you will see the numbers go up
but the long term fix lies in addressing the broader terrain and lowering the autoimmune inflammation 💡
In this week’s thyroid musings (my free thyroid musings newsletter) I will be sharing a deep dive on ferritin, inflammation/ hepacidin connection, what to test for the full picture and my fave supplements.
Not receiving my emails? lets fix that.
