I wrote a few days ago regarding a possible B12 deficiancy. I recieved some really useful information on here and although i have not recieved an official PA diagnosis off my doctor it appears i probably do have it as i had a very low level of 91 last year and have been put on injections every 3 months. During all this i decided to have a few tests carried out via medichecks. (I have not used them before so not sure how accurate but have heard good reviews and they seem legit from info i have read) They do a fatigue and tiredness blood test which checks full iron panel, thyroid and vitamin D. All came back fine except for Vitamin D. My result was 37.3 nmol which suggests an insufficiancy which could lead to a defficiancy, and they recommended taking a vitamin D supplement of 800 - 2000iu for 12 weeks to raise this and then re-checking my level to see if it has improved. If so i can then reduce supplementation. I also did an active B12 test which came back as high, but because i have had injections in recent past, i realise now it would be high so the result is meaningless. I have been feeling very tired, lightheaded, achy musles etc. Which may be due to B12 (ive learnt you can still get symptoms with a normal result) but also as i have now learnt i have a low level of Vitamin D, could this could also be a contributer to how ibam feeling? Would having PA effect vitamin D levels? Sorry if this is a silly question as i know PA is related to B12 but im surprised i am low in vitamin D as i am outside quite a lot and we have had really good weather lately! I am thinking of trying a vitamin D spray as it appears to absorb quicker, has anyone used one and have any recommendations of a good one to purchase? im due back at my doctors this week for some more tests (glucose and calcium) so i will discuss the vitamin D results with her also.
