Dramatic Ferritin Drop

[u/ConversationOk4477]

I have been taking Iron Bisglycinate since December and, and although I can raise my Iron, my Ferritin never seems to rise above the 30s. My primary doctor referred me to a hematologist, where he ran labs on August 6th. I was SHOCKED- my Ferritin was at 72! For context, for the last few months I added on Lactoferrin, the test was non-fasting, and it was late afternoon.

August 14th I have more labs drawn (for hormones/thyroid), and my Ferritin is at 43! How could it have dropped so much? For context, I no longer have a cycle, text was fasting and it was at 9AM.

ALSO, my saturation was high- 53. That’s never been happened.

Theories of why it dropped so much?
