My daughter was diagnosed with sevre vitamin D deficiency last year aged 10. For years she had been complaining of painful joints and had started to limp. She was referred to a rheumatologist and her levels were found to be 14. After a four month course of high strength liquid vitamin Dher joint pain has nearly gone. I also am on vit d but why our levels are low we dont no. Nearly every winter we go to the Canary Islands for a week to get some sunshine and we have been doing this since she was a baby apart from two years when I was unable to travel. The cost of this treatment was probably high but if left undiagnosed/treated at her age would have been far more costly at a future date not to mention the efffects on her body. We eat healthy so can only guess its an absorbtion problem. However now we are on the low dose vitd(400iu) and I do wonder if this is effective in maintaining levels as her levels havnt been monitored since and I buy just a multivitamin with d3 in it as she wont take cod liver oil which was recommended.
You have only to google vitamin d3 deficiency - and lots of info is available. lts recommended for babies/toddlers to be on 1000ius daily. Older children/teenagers need 5000ius - and adults up to 10.000ius daily. lf you have been tested and found to be deficient you will need more. Vitamind3world.com also do test kits to calculate your levels. ldeally, your levels should be 150/224nmols. l have been taking 20.000ius daily to try to get a better level - this winter. l have books on vitamin d3 -[ that l got from amazon]. The Vitamin D Cure /Overcoming Multiple Sclerosis.
l can remember, as a child,having painful legs - and being told it was ‘growing pains’. Well we all know now it was not.
l - like many others on this site get our vitamin d3 softgels 360 Healthy Origins from amazon - seems to be the cheapest. At about £15 for a years supply. The gel capsules can be pierced and the oil squeezed onto food or juice for small children.
To be able to EAT enough vitamin d3 - you would need to eat about 6 portions of oily fish a day. Only eskimos can do that. 15mins of full sun on your exposed body is the equivalent of 20.000ius.
The test for vitd3 is easily done with a ‘spot’ test. lts just a very small prick into the finger.
