@nicolesnutrition: The new ASH guidelines just doubled the ferritin cutoff for iron deficiency, from 15 to 30 ng/mL. Even better if you’re menstruating or pregnant? 50-80 ng/mL. If you have a thyroid condition, this matters even more: -Your thyroid needs iron to make and activate thyroid hormone
-Thyroid conditions can affect how you absorb and lose iron
-Ferritin is also an inflammation marker, so it can look normal or even high when iron stores are actually low (this is especially common in autoimmune thyroid conditions) That’s why one number never tells the whole story. Ferritin, transferrin saturation, and a full thyroid panel should be read together. 👉 Save this post and pull up your last labs.
