    They reckon fifty per cent of the UK population have low vitamin D. What is his blood measurement? I would not have thought a Dexascan necessary at his age unless recommended by his GP. The important thing is for us to eat a good balanced diet, which a lot of us do not. The trouble with Vitamin D is that less than twenty per cent comes from food it is mainly from the sun. As we all use ridiculously high sun screens nowadays this blocks out the vit D. Also sitting indoors playing video games does not help either.

    Full blood count including iron test would be a good one seeing as he's tired. 

    Just out of curiousity, what are his vitamin D levels? Is he vegan... if so a B12 check would be required to determine his levels.

      He should be feeling well within a month if the vit D supplements are a good dose. For levels below 25nmol/litre dosage should start at 10,000 IU for 3 months at least, then a lower dosage for maintenance if he should require them. Hope he's back to normal asap. x

      800IU a day is what I was prescribed with levels of 5mmol/litre. I had to go back to my GP 3 times to insist on higher doses and vegan alternatives. In the end, I bought my own from the manufacturers and am taking 10,000IU a day. I tried higher doses but they had a laxative effect on me.

      I don't think the NHS care for vitamin D deficiency, nor do they want to prescribe adequate supplements. 

      If your son'r levels are below 25mmol/litre, then he should be on HIGHER doses than 800IU a day.

      Today I'm ringing my doctor to refer me to the hospital for an injection of vitamin D2 (Ergocalciferol) as my levels will not improve unless I get a higher dose and supplementing myself has flared up my Crohn's. They routinely do give injections - 300,000 IU - according to how deficient you are. I'm dying here!

      It can take up to 3-6 months to get vitamin D levels up to normal, but if taking higher doses, then you should be feeling the good effects within a month.

      Agony. I have Osteomalacia (adult Rickets).

      Rang my GP who says he'll check my levels in 4 weeks time.

      I'm in pain 24/7 and have very little energy. I go to bed with a huge headache and wake up with an even bigger one. I also broke my thumb a few weeks ago, trying to assemble a metal bed. That's how soft my bones are. I've been referred to see a rheumatologist - only after insisting I see someone because this isn't right that I just swallow some supplements and wait for the pain to subside... Rheumatologist appointments are fully booked and there's a LONG waiting list. When I booked, over 6 weeks ago, I was told I was going to wait 14 weeks for an appointment as that was the soonest.

      So I wait... Meanwhile I do more research on vitamin D and what doses I can tolerate along with ensuring I have adequate amounts of vitamin F and K (linolic acids and green veg).

      B12 levels are exceedingly good as are my Calcium and electrolytes (Phosphate, Magnesium, Potassium). It's just my iron, blood and vitamin D that have been awful for a while and taking time to put right. Crohn's disease depletes my stores or something... But I wouldn't have a problem with my gut if my vitamin D levels were normal. Continuous circle.
