i don't know what you mean by you "don't have time for this. " curing a vitamin d deficiency is as easy as taking a pill once a day. low vitamin d levels have been associated with bone pain general muscle weakness and even cancer (thought that's unlikely in a young person). it's doubtful your sleepiness and lack of concentration are due to vitamin d deficiency but i suppose anything's possible. you don't need any "other test" to determine the cause of your low vitamin d levels. it's pretty simple: you're not consuming enough vitamin d and you're not getting enough sunlight on your skin. this is a very common problem. on the one hand we medical professionals tell people to wear sunscreen. on the other hand we tell them they're deficient in vitamin d. the solution is to continue wearing sunscreen when you go in the sun for prolonged periods of time and to take vitamin d supplements. if you have no personal or family history of skin cancer you probably are safe to get 15-30 minutes of sun per day on your skin. this will help boost your vitamin d levels. given how very deficient you are in vitamin d i hope you took the prescribed 50 000 iu of vitamin d every other day until the prescription was gone. the usual length of therapy is a couple of weeks. you should get re-tested if you have not already done so. and then you may need to continue taking inexpensive vitamin d supplements for awhile until your levels are within normal range. please note you should not continue taking 50 000 iu of vitamin d indefinitely. that's a very large dose. if you have any questions consult your health care provider. wishing you well! i don't believe the answer is always so cut and dry. my vitmain d level has been low and getting lower for at least 5 years now. i don't tolerate the heat or sunshine so i don't get very much sun. but i have been pushing myself to tolerate it. but i've been on several very high courses of good quality vitamin d supplements and the mainstays of my diet are all vitamin d rich. but there was never even a slight rise in my levels. at last check my levels were in the single digits. incidentally i am always tired and always in pain these days. absolutely! i have had similar symptoms along with cardiac and autoimmune disorders. my vitamin d level is 13 and has runned low for years. i too never worried about vitamin d but i've found out that it's a huge problem and runs in my family related to synthesis problems of vitamins and enzymes. have levels check regularly even after normal labs and please take your vitamin d with lots of sunshine and diet rich in vitamin d c b12 calcium etc. i've gotten much better! they all work together. what i meant is i don't have time to feel so down with all my responsibilities i did start taking the pill recently. i was asking what other tests can i do to determine the cause of feeling sleepy all the time and having concentration issues and if it's somehow related to my vitamin d insufficiency. nonetheless thank you for putting time and answering. greatly appreciate all the answers.
vitamin d level was 15? my doctor prescribed 50 000 iu every other day. details are below. so my vitamin d level was 15 last year i did nothing about it unfortunately but i was. -always sleepy. - i would take long naps during the day. -i can't concentrate. - anxious. -knee pain once in a while it starts hurting and feeling really stiff goes away with rest. i feel bad because i'm in college and i don't have time for this i have lots of work to do. do you guys think this is because of my vitamin d levels? also what other tests should i do to determine the cause? thanks a lot.
