Summary

UK medical experts say TikTok’s “ferritin face” trend is not a diagnosis and urge blood tests.
Sue Pavord of Oxford University Hospitals says ferritin below 30 µg/L signals iron deficiency, below 50 µg/L indicates risk.
World Health Organization defines ferritin under 15 µg/L as deficient, while UK guidance flags under 30 µg/L as low.
Experts advise high-risk groups—heavy periods, pregnancy, vegans, athletes—to request full blood count, ferritin, B12 and folate.
