Vitamin C and Iron supplements might not do it. Vitatron C did nothing, Iron Folic did nothing (used to pre vax), Ferraris Sulffate constipated like crazy, Heart & Soil Life blood mildly helped but never increase. My Ferritin was 5 - my hair was falling out, dry skin, brittle nails, heart palpitations, super tired, and now bone pain. My PCP and Hematologist said the extreme low Ferritin was to blame. Did IV Iron at the end of last summer even though technically not anemic but my symptoms dramatically improved after 5 doses of IV iron. Level went from 5 to 128!!! Unfortunately over the last 8 months I've been steadily dropping and back down to 11 as of a week ago. For your health, please keep an eye on this and potentially get a Hematologist referral if you're experiencing any odd symptoms (especially any of the above I've listed).
