I stupidly did not ask my doctor what number my vitamin d levels was the doctor just said slightly low. He gave me 10 x 20'000 iu vitamin b3 to take over two days and 1000 a day there after . Is it possible to know my level from dosage given to me . Elaine

    First, I am not at all sure what you mean by “10 X 20,000 iu”? Do you mean take 100,000 iu the first day and 100,000 iu the second day? Your level is probably fairly low but no way to tell the actual number. Also be aware that after the initial “large” dose that the 1000iu a day will probably not be enough to keep you at a level of 50ng/ml that we promote at the VDC. It usually takes 5000iu a day to reach and maintain the 50ng/ml. (It is a guess that you would be OK for a month and then your levels may start to decrease again.) The 200,000 iu is like taking 6600iu per day for an entire month. I hope he/she plans on retesting you in a couple of months.

    Thank you for your reply , yes I did mean 100’000 per day for two days . Do you suggest I should take 5000 a day from now on.

    No, I meant that after taking the big doses and the 1000iu a day, that your level will probably be OK for a month. If you are trying to maintain a level of 50ng/ml from then on you will probably need to take the 5000iu a day. I do not know what your level was and I do not know what level the doctor is trying to reach. Maybe he or she is only trying to get you to 20ng/ml and they will be happy with that level. Do you have any health issues at the moment?

    My health issues are not too serious I went to the the doctor for backache which I have had for over 5 years which left me bed ridden for months on end. He finally did blood test which only showed vitamin d deficiency. After reading the symptoms of other people with vitamin d deficiency I realised that they match a lot of symptoms I have been having that I did not think was related, the list is quite long. I have had consistent gastritis which has baffled my doctor as to why it keeps on returning, do you think it has anything to do with vitamin d deficiency.

    The Vitamin D deficiency could be the reason for the gastritis. Vitamin D has a lot of influence on the immune system so it would not surprise me if it “goes away” once you have supplemented enough. Backaches, especially lower back problems are also associated with Vitamin D deficiency.
    Please keep us informed of any symptoms/problems that disappear with supplementation. We like to hear success stories!

    Thanks that is encouraging hopefully it may go away fingers crossed. The doctors in the UK are not as informed about the deficiency as America, I was told it was low, to take the vitamins , sent away to get on with it. It is only reading sites like this one that has informed me about the possible links with other symptoms I have been experiencing, so just wanted to thanks it has been helpfull

    I did not know wether to start another question or continue with this feed it’s been a while since my last question. I finally found out my blood levels was 15 mnol /l which was lower than I thought. On your advice have increased my intake to 5000-7000 iu a day. I have been taking omeprazole for a few years but stopped on your advice to fella sufferer that it can make you deficient in magnesium, do you know if gaviscon has the same effect. Though the symptoms have improved over the last month I feel I still need something for the indigestion. My thanks in advance.

    Proton pump inhibitors are what you want to avoid, “omeprazole (Prilosec, Prilosec OTC), lansoprazole (Prevacid, Prevacid 24HR), and omeprazole/sodium bicarbonate (Zegerid, Zegerid OTC)- are available as both prescription and nonprescription drugs.” The above are the ingredients you would want to avoid.

    Gaviscon is fine. Also from Healthline “If you suffer from occasional heartburn and have not been diagnosed with GERD, nonprescription antacids such as Maalox, Mylanta, Rolaids, and Tums, or acid-reducing drugs known as H2 blockers, such as cimetidine (Tagamet), famotidine (Pepcid), nizatidine (Axid), and ranitidine (Zantac) will very likely provide relief.”
    Elaine your level was “extremely low”. Do you plan on getting retested at some point in the near future? Given it was that low you probably should have been taking 10,000iu for a while. You really need to see how much progress you have made!

  •  elainedbelgrade10135000 on

    Thanks for your response, yes I will get retested but I may not go through my doctor as he is not aware that I have upped my vitamin d from 1000 iu to 5000 iu and UK doctors don’t understand that is not enough. Can I use your test if I live in the UK or is it exclusive to the USA.

    Sorry just read your disclaimer and it has answered my question. Do you think I should take 10,000 iu now or wait until I do another blood test depending on the result.

    I think after taking the Vitamin D for two months, you should try and retest to see how far it has increased since you were so extremely low. (Honestly your doctor should have said come back and get tested to make sure whatever level he was trying to reach for you happened.) Since your symptoms are getting better, that is a good indication that you are headed in the right direction.
    Under https://www.vitamindcouncil.org/about-vitamin-d/testing-for-vitamin-d/ is this if it helps! City Assays -This company is based in the UK and offers the cheapest test internationally (about $48 USD) and in the UK/Ireland (£25).
    I was trying to find the Vitamin D lab test range that the UK uses but I could not find it quickly. For example Labcorp here in the US is 30 – 100ng/ml which translates to 75 – 250 nmol/l. So here in the US as long as you are under 100ng/ml no doctor can really argue with that. It is just the upper range.
    Please let me know what happens!

    I did the blood test and got the result back and my levels have increased to 89 . 9 nmol which I worked out to be 36 ng . I was very pleased to see a big increase so soon. Do you think I should stay with about 8000 iu or should I decrease the amount to 5000iu, I would value Your opinion . I still feel lathergic sometimes and have mussle pain ect though symptoms have greatly improved . Thank you in advance.

    The 36 ng/ml is correct. Since you are not at 50ng/ml and still have symptoms, I would stay at the 8000iu. For how long, I am not sure. I do not know whether you should stay there until all symptoms are gone then cut back or cut back soon. How about two more weeks at 8000iu and then try and decrease to 5000iu BUT NOT below that. If symptoms start to return at that point then increase the D3 back up again. Let me know how things go! I am glad you are feeling better!!!

    Just thought I would would let you know how I was doing. I just got my results back from a blood test I done a couple of weeks ago it come back as 186mnol. I was very pleases with the increase. While I feel miles better some of my symptoms still come and go,some days I feel normal but I still get days when fatigue gets the better of me. I also have back pain when I sit for a while and my digestion is still poor. I would like to keep my levels at 74 ng do you think I should reduce my intake to 5000ui (I have been taking 10000iu ) or will my levels decrease. Thanks in advance

    Glad you wrote back to tell me how you are doing!
    Have you been taking the 10,000iu since May 2015? If so then I would not decrease if you want to stay at 74ng/ml. After that length of time the only way I think it will go higher is if you take more Vitamin D or go out in the sun while taking that amount.
    Now the next part, I will have to leave up to you. Have you thought about taking more than the 10,000iu a day to see if the remaining symptoms stop? The official range upper end is 100ng/ml and the official no harm will happen is 150ng/ml. Just some food for thought.
    The only other thing I can think of is do you take any supplemental magnesium and/or calcium? Have you ever taken probiotics for your stomach?

    Answered by  IAW on
  •  elainedbelgrade10135000 on

    Thank you for your reply. I have been taking 10000iu for about 4 months before then I was taking 8000iu . I have considered taken more then 10000iu but have always been apprehensive in doing so. I may try it for a few weeks to see if I feel any different. I take 600mg of magnesium citrate but only take 200mg of calcium in a multi vitamin do you think I should take a calcium supplement, I have dairy in my diet which I thought maybe is enough, is there any harm in taking too much calcium. I will also try the probiotic for my digestion which is a good suggestion, I have in the past taken them and did feel better.

    Dr. Cannell once said not to take too much calcium, probably not more than 500mcg a day because there is a lot in most people’s diets. So if you feel there is enough in your diet then do not worry about it. Have you read http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/? You may want to add Vitamin K if you do not get enough in your diet.
    The probiotic may work even better now since you have Vitamin D to go with it.

    Well I don’t really know. I can honestly say that there has not been many, if any studies done. I found one study that was done but without even looking it up, I am sure they did not use enough Vitamin D to know whether it would help or not. If studies use very low amounts of Vitamin D, it may not be enough to show an affect and then they declare it does not work.
    So how do you feel by now and how much Vitamin D are you taking???????

  •  elainedbelgrade10135000 on

    I flitter between 5000iu and 10000iu, I would stick with 10000 but sometimes keep getting dead hands and feet in the night and pin and needles during the day which think it maybe too much vitamin d I take. I had some blood taken last week so will see what the results are . My anxiety has been pretty bad but I overall health has really improved. I took the probiotic for I while which helped with the digestion, someone told me coconut water helps with acid so have been drinking it everyday and do far it has worked. I am still getting tired but less so then before. Thank you for your replay I am sure I am not the only one who thinks you do a wonderfully job helping people get better.

    Thanks for the nice comment!
    When you said “keep getting dead hands and feet at night”, I was also having this issue awhile back only just in my arms and hands.It went away, so I have not thought anymore about it.
    I have two suggestions though. I just found out last week that proton pump inhibitors can also cause a Vitamin B12 deficiency. It would account for the “pins and needles” and anxiety. I know you stopped taking them awhile back but still you could be deficient. You can read up on it. Here is the US the low end of the range is probably too low and should start at a minimum of 500-550pg/ml. https://chriskresser.com/b12-deficiency-a-silent-epidemic-with-serious-consequences/. (He discusses which type of B12 he feels is best.) “there is no upper tolerable limit for B12 because high doses are considered safe for most people.”
    Above I once said not to take too much supplemental calcium BUT lack of can also cause “pins and needles”, so you may want to rethink that.
    One other thing you may want to investigate is “PRE biotics”. Dr. Cannell once talked about both PRE and PRO biotics and I had never heard of the “PRE”.
    Well now you have more homework Elaine!!
    I also greatly appreciate letting me know how you are doing!!!

    Answered by  IAW on
  •  elainedbelgrade10135000 on

    Thanks for your replay, the blood test I did this week by my doctor I think covered b12 so I will look forward to the result, I am vegetarian and have the digestion conditions they mentioned (gastritis and ibs ) I think I would benefit from taking b12 so will start today. I did start to take more calcium but got a bit nervous and stopped , you hear bad things about too much but will start again and see what happens. I will also research prebotics. I will let you know my blood results when I get them. again thanks.
