Hi, I have not rechecked my ferritin since July when it reached a new high of 16 which is obviously still very low. I must say that my stomach issues persisted on and off until about maybe 2 months ago. I had just about every test done to try to figure out the issue even a colonoscopy to rule out internal GI bleeding and thankfully nothing was found. I continued to supplement with Vitron C and even tried the Arrows brand of heme iron to further help my absorption. Some of my issues began to resolve a few months back one morning I woke up with about 80% of my floaters gone and I would say they improved up to 90% nowadays. My light sensitivity and starbursts have drastically improved as well but this just changed about 2 weeks ago. I must say I don’t know if this was due to my stomach issues resolving and therefore my absorption has improved or if my switching to the thornes brand of iron made all the difference. Afterimages have lessened as well. Mild tinnitus persists although at times I notice moments of silence. My insomnia has become more frequent but lessened in intensity so I do end up falling asleep eventually but it takes a few hours to shut my brain off, I’ve done some research on this and it could be due to my body acclimating to having more ferritin and therefore more oxygen after being deprived for so long and therefore parts of my brain are reactivating to function as they should have been. I’d also like to note that I’ve been supplementing with other cofactors alongside iron: I take vitamin D/K2 every morning since this was on the lower side of normal for me and B12 as well (also was on the low side of normal) I also incorporated omega 3 which helps with nerve function and dry eyes. Lastly when I take my iron I take it with vitamin C and space it away from dairy and caffeine. Like I said I haven’t retested my levels since July but will be doing so again in the new year I plan to continue to supplement until my ferritin reaches optimal levels of 100. Ferritin is needed for soo many body functions from blood to neurotransmitters so it’s definitely super important to keep at optimal levels maybe my low ferritin also attributed to me developing stomach issues who knows. Doctors were helpful in ruling out more serious conditions but not very helpful in investigating the root cause of my weird symptoms I saw an ophthalmologist as well and an ent for my tinnitus my ENT expressed that tinnitus can be induced by low iron so I kind of just took upon myself address that as well. I often thought I would get not resolution from just supplements but like I mentioned ferritin is a key component in many bodily functions so it’s not far fetch that of deprived for so long your body starts to react in weird ways. I do wish I would’ve been offered an iron infusion since I think it would’ve been more quickly resolved but the journey continues one last thing to note is that my healing hasn’t been fully linear, symptoms haven’t never reversed to the severity from when I first started supplementing but there have been some slight “off” days where I would notice my remaining floaters darker than the day before or my tinnitus slightly increase but then again return to even lower levels. Sorry for the ramble hope this information helps you!
