Given my symptoms should I be on more dose of my prescription supplements please? As well as thyroid medication I have been taking 1 200mg ferrous fumarate tablet since 2013, vitamin D3 800iu since 2013 and 5mg folic acid since November last year.
Ferritin 19 (15 - 150)
Folate 2.31 (2.5 - 19.5)
Vitamin B12 208 (190 - 900)
Total 25 OH vitamin D 44.2 (>75 adequate)
Symptoms are things like not concentrating very well, hard stools, heavy periods, dry skin, pins and needles, breathlessness, headaches, fatigue, muscle cramps, muscle twitching and joint pain. Feedback is appreciated. Thank you in advance.
