Ferratin & Folate

Just gave my reults on ferratin (23) & folate (7.3) but perhaps they are wrong because I have been using the B12 spray for about a month or so. My levo has been reduced a little to 5 x 100 & 2 x 125mcg and I am very tired (no thyroid gland). I have had anaemia on and off for most of my life, but the docs receptionist said my results were normal!!!

Pepekins, supplementing B12 won't affect your ferritin and folate. Folate is usually good around half way through range which generally goes up to 20, so take a B Complex which contains a little folic acid to improve the folate and keep the other B vits balanced.

Ferritin is optimal half way through range. 23 is low so supplement iron until it is 70-90 or halfway through range. Take each iron tablet with 500-1,000mg vitamin C to aid absorption and minimise constipation.

Low ferritin may be why you are fatigued but I do think 100/125 is a low dose for someone without a thyroid gland.

ps I shall delete your duplicate post.


Ferritin should be well over 70 at miniumum

Depends on ref range but it must be halfway in any range or your body cannot utilise the levothyroxine

Are you coeliac because that can be why some people cannot raise ferritin levels easily


No I am not coeliac but I don't think I do raise ferratin levels easily. I try to have a little red meat each week and eat plenty of greens.


Please consider trying haem (also spelled heme) and/or ferritin supplements.


Do you eat potatoes with your red meat and greens? They will increase absorbtion. Or you could take vit C with your meals.

Don't rely on spinach for your iron. It has plenty but also contains a substance that blocks absorbtion.


I think the difficulty is where do you stop! I take stuff for bones and flexibility, Rosehips for Vit C, Omega 3 capsules, a powder for energy and of course the thyroxine. However maybe instead of the energy powder a vit B complex would do the trick or iron!!


Oh and Vit B12 spray and cod liver oil!!!
