Iron Supplements


Could anyone advise me about iron supplements please? I have Hashimotos and amongst various other tests my ferritin came back at 25 (range 15 - 300). My GP said it was low but obviously still within range. I understand from this site that it needs to be at the higher end of the range. Are there different types/strengths that anyone could recommend at all?

IWNBB, ferritin is optimal half way through range. Try Ferrous Fumarate 210mg and take each tablet with 500mg-1,000mg vitamin C to aid absorption and minimise constipation. Take iron 4 hours away from Levothyroxine and retest ferritin in 6 months.
