The Scientific Advisory Committee on Nutrition consultation on its draft Vitamin D and Health report is open for scientific comment.
This consultation (comments) closes at 23 September 2015 2:00pm
Remember that the government (=taxpayer) pays for all medical treatment in the UK
- and it is delivered by the government (=National Health Service)
So they don't want the level of Deficiency raised ( 25nmol/L = 10ng/mL )
- and they don't want any new illnesses specified that require treatment !
A cynical person might suggest that this report is politically biased
Hi Barbara ( bboucher at doctors.org.uk )
This is a step ahead for the UK, of course. Congratulations to you and others in the UK who worked for this.
But 10 micrograms/d (400 IU/d) is a pitifully small dosage, considering the high latitudes of the UK. It is also too low concerning the cloud cover that covers much of the UK population in winter.. For example Edinburgh is at 56 degrees N. Analysis from satellite sources indicate extensive cloud cover in winter in the UK. And, sadly, the UK probably still burns some coal containing sulfur, adding particulate air pollution to the atmosphere that tend to absorb and backscatter solar ultraviolet B.
Another reason is the UK has a colorectal cancer incidence rate (30 per 100,000 per year) in the top quarter of reporting countries of the world and breast cancer (90 per 100,000) in the highest 10% of countries of the world (Mohr et al. 2008; Cuomo et al. 2013). Vitamin D repletion will prevent most cancer in women (Lappe et al. 2007), including colorectal and postmenopausal breast cancer. This will require not 400 but 1200 IU/day (30 micrograms) of vitamin D3. This should be consumed with calcium, 1000 mg/d for men and boys 9+ years and 1200 mg/d, in women and girls 9+ years, the calcium ideally from diet.
Yet another reason is the high rates of multiple sclerosis in the UK. Vitamin D deficiency plays a central role in this disease.
The incidence rates are 10-12 per 100,000 in Scotland the prevalence is 200-209 per 100,000 population (Lothian and Border areas, Rothwell & Charloton, 1998). The authors of the Scottish study asserted that its incidence rate of MS is the highest ever reported in the world. For a rough comparison, the prevalence in California-born residents of Los Angeles was 40 per 100,000 in an earlier survey (Detels et al., 1978). There are many other studies in support of this association.
Vitamin D deficiency also has a strong association with incidence of type 1 diabetes. The UK (Oxford) is in the top 10% of areas that have type 1 diabetes registries (Mohr et al., 2008). Use of vitamin D would reduce incidence of this serious disease in the UK should also be considered. This is another reason to recommend 1200 IU/d (30 micrograms/d) rather than 400 IU/day.
I could list many more non skeletal diseases that the proposed 10 microgram/d dose is too small to influence. The UK is sadly missing a chance to achieve these benefits of vitamin D3 by recommending a dose that is too small. The recommended dose of 400 IU/d (10 micrograms/d) would raise serum 25(OH)D by only about 2.8 ng/ml (7 nmol/L).This would do virtually nothing to reduce incidence of cancer, multiple sclerosis, type 1 diabetes and several other important non-skeletal diseases due mainly to the vitamin D deficiency that is rampant in the UK.
Vitamin D Recommendations around the world - IU and ng has the following chart
Note UK proposed 400 IU is lower than most of the world
Chart of Vitamin D levels vs disease - Grassroots Health June 2013 had the following chart
- UK (SACN) is ignoring scores of Vitamin D studies
- 10X increase in cost of vitamin D per child-year in UK in 6 years - Aug 2017
- 400 IU Vitamin D is enough for majority in UK, even in winter (nope) – Nov 2015
- Only 1 in 10 UK parents had been told about vitamin D by their child’s doctor – April 2015
- Only 1 in 4 UK children had EVER gotten vitamin D supplements – April 2015
- UK people and doctors still clueless about vitamin D – Survey Oct 2014
- UK-NICE draft on vitamin D – extremely low doses and levels– May 2014
- Post-mortem analysis of children in London Hospital – only 1 child had adequate level of vitamin D – July 2014
This UK Study defined adequate as > 32 ng, NOT 10 ng
- Why are doctors reluctant to accept vitamin D
- Let 1000 die from vitamin D deficiency rather than incur 1 lawsuit
- A look at inner workings of committee looking at vitamin D for UK - Dec 2012 the same commitee as on this page, still thinking
- Is 50 ng of vitamin D too high, just right, or not enough has the following notional chart
Consensus: 0 ng is bad and 30 ng is good/ok
