Been taking hemaplex iron as I read someone on here rave about the results obtained within 2 months. My issue is I keep waking in the night with stomach pain. I am taking 1000 vitamin c but it's still bunging me up so to speak. Wondering whether to increase the C further still? My Ferritin is only 22 and I'm feeling tired still in 2 grains of armour. Thanks in advance.
