Somewhere in an earlier thread, I had posted something about
the UK was going to be giving out free D to high risk groups for Covid. Though I thought their doses were ridiculously low, this at lest seemed like a good step forward from those in authority in the UK. Well, it seems I celebrated too early. https://archive.is/msqfb
There is currently insufficient evidence to support taking vitamin D solely to prevent or treat COVID-19, according to new guidance.
However, experts confirmed current advice for everyone to take a vitamin D supplement throughout the autumn and winter. ( BB adds: ?????? ).........................
Evidence Is 'Inconsistent'
The scientists agreed that low vitamin D status was associated with more severe outcomes from COVID-19. However, they said it was not possible to confirm causality because many of the risk factors for severe COVID-19 outcomes are the same as the risk factors for low vitamin D status.
Other problems with the available evidence were cited as inconsistencies between studies, and differences between supplementation doses, settings, populations, durations of trials, and definitions of outcomes.
Prof Ian Young, chair of SACN, said: "This evidence review confirms that currently there is not enough available evidence to determine that there is a causal relationship between vitamin D and COVID-19."
The guidance recommended that more research be conducted.......".
Or, in my case, call me crazy, I will just continue to take Vitamin D and other possible helpers, and encourage every one I care about
to do the same, after researching this for themselves. I'm not waiting for the never ending recommendation "that more research be conducted", though I do hope they actually do so. Besides, they apparently are not considering the RCTs which have already been done.
"Dr Paul Chrisp, director of the Centre for Guidelines at NICE, said: “As research continues on the impact of vitamin D on COVID-19, we are continuing to monitor evidence as it is published and will review and update the guidance if necessary."". Well, no need to rush.
"One recent study, published in the journal Nutrients, suggested that a high-dose booster therapy of vitamin D in its 'parent' form, cholecalciferol, regardless of baseline serum 25(OH)D levels, appeared to be associated with a reduced risk of mortality in acute inpatients admitted with COVID-19.
The observational study involved 444 participants with a median age of 74 from Tameside General Hospital in Ashton-under-Lyne.
The authors call for further work...........". LOL! Or, some of us might choose to not wait for further work, and go ahead and make certain we are not deficient or even insufficient on D. Like me.
"They point out that if beneficial, high dose therapy with vitamin D would be inexpensive and widely available.". Well, we agree on that! And considering the RCT in the OP of this thread, a few other RCTs with the same results, and about
a bazillion observational studies all pointing in the same direction, I do start to wonder if there is actually any amount of evidence that would be enough for these people? Besides, I'm willing to bet money that almost every one of those advisors are supplementing at least with a couple of thousand IU of D.
"The panel was concerned that not everyone was aware, or were following, UK Government recommendations to take a supplement between October and early March when people in the UK do not make enough vitamin D from sunlight.
They stressed that everyone should consider taking a supplement containing 10 micrograms (400 international units) of vitamin D daily.
The panel also stressed that this was particularly important during the COVID-19 pandemic, when people may be indoors more than usual.
'Alarming' Vitamin D Deficiency in UK Ethnic Groups
New research found that 57.2% of people with Asian backgrounds living in the UK are deficient in vitamin D (levels below 25 nmol/L) during the winter and spring..............".
Well, may I suggest if "not everyone was aware, or were following, UK Government recommendations to take a supplement between October and early March...." it might be because of articles like this that seem to be saying "we can not recommend vitamin D supplementation to improve your odds against- among other illnesses- Covid-19"?
"The study used data from 440,581 UK Biobank participants.
"The rate of severe deficiency was much higher in most population groups than we would have expected, so these results are really very alarming," commented Prof Elina Hypponen from the University of South Australia, who led the study.
The authors said the results strengthened calls for a mandatory vitamin D fortification programme in the UK."
Well, which is it? Should they supplement or not? After all, the title/headline is: "'Not Enough Evidence' to Recommend Vitamin D for COVID-19 Treatment
December 17, 2020
There is currently insufficient evidence to support taking vitamin D solely to prevent or treat COVID-19, according to new guidance." And I seriously doubt the recommended tiny dose of 400 IU, or food fortification, is going to do much to get levels for most folks up above 30 ng/ml, considering that nature will supply > 10,000 IUs from exposing a lot of skin to sunshine for 30 minutes.
