Feeling great. No symptoms I'm aware of.
Just a heads-up to those guys who have tested very low on their Ferritin-
My functional doc discovered I had low ferritin (11) a number of years ago, and I was having minor gut issues at the time. She was looking for the root cause since the low ferritin in an adult male was unusual. The possible causes she considered included internal bleeding, Celiac disease, others. She zeroed in on Celiac after more diagnosis. I am a skeptic generally, and my fitness level and health caused me to discard this diagnosis ("this is bs.... there is no way I am celiac...") . The antibody test was positive...then the biopsy was positive and it was impossible to refute...
Just saying- malabsorption (from Celiac) will cause low ferritin. Certainly donating blood will whack your Ferritin temporarily, but if it does not recover, you should consider other causes-
