When Your Health Turns On You: #Hypothyroidism --- 9: Covid-19 and Vitamin D – Jan 2021 Update

Vitamin D3 capsule

When I started this series in February 2020 I never expected still to be adding to it in January 2021. There again, one year on from the first Covid-19 hospitalisations in the UK, no one here expected to be living under Lockdown-3. It could be worse, and it is in some parts of the world; at least we don’t have a curfew.

However, the UK figures, horrendous as they are, speak for themselves:  3.8m people have tested positive for Covid-19; deaths within 28 days of a positive test have topped 100,000.

There is good news: 9.97m people have had the first dose of available vaccine; 491,000 the follow-up dose. In my area those aged 70+ are being called, which means that the vast majority of the most vulnerable (80+) have been vaccinated.

The even better news is that people are beginning to take seriously the role of Vitamin D within the human immune system, except, it seems, the Government and its health advisers.

One of the leaders of the publicity push – apart from Dr John Campbell, much mentioned during this series – is David Davis, MP, who has been writing articles in every newspaper that will print them. Mr Davis is an old-school politician: not only did he work for a living before entering politics, he has a Joint Honours degree in Molecular Science/Computer Science, so he knows what he’s talking about. More important, he’s not afraid to stand up in Parliament and make the case for Vitamin D, as he did on 14th January, now available on YouTube: https://youtu.be/Gog5mgBv0hM

The video is 24 minutes in total, and an eye-opener. Who knew, despite growing evidence from around the world, funding for trials to ascertain the efficacy of Vitamin D had been refused – twice? The response, towards the end of the video, from NICE/Public Health England is, shall I say… beyond belief.

Today I watched a discussion between David Davis and Dr John Campbell which brought to light some fascinating, and quite horrific, points: 

  • As long ago as 1983 (read it and weep) the medical profession was beginning to understand the impact of Vitamin D on the body at cell level, and particularly in the immune system.
  • In 2017 there was an article in the British Medical Journal suggesting that Vitamin D could inhibit respiratory infections by up to 70%. (Note: around 17,000 people die annually in the UK due to seasonal influenza – Public Health England figures.)
  • In March 2020 Mr Davis ramped up his own study, believing there is a correlation between more people dying of Covid-19 with low Vitamin D levels (ie the elderly; darker skin tone; co-morbidities), and if correct low Vitamin D “could” account for around 50% of Covid-19 deaths.

The discussion is well worth watching. It is 1hr 20mins, but the most pertinent information is within the first 30 mins: https://youtu.be/bQyhjQUjHjU

How about me with an autoimmune disorder I strongly suspect – a suspicion boosted by the above discussion – was caused by a long-standing lack of Vitamin D? I shall reiterate the results from my last two Vitamin D blood tests which, let me remind UK readers, I have had to pay for:

mid August 2020: 124 nmol/L             early November 2020: 109 nmol/L
(Optimal is 125-150 nmol/L)

Considering I have stayed on my relatively high level Vitamin D3 supplement and its co-factor protocol throughout, what prompted such a fall in only two and a half months? Lack of sunshine. It was autumn.

I am intending to pay for a further test at the end of March, the end of winter. That should prove interesting. I’ll keep you posted.

Stay safe. 


Update 30 March 2021:
My paid for panel of blood tests are completed. All results look reasonable;
Vitamin D stands at 128 nmol/L (tick!).

  1. Thanks for sharing this vital information, Linda. The genie is out the bottle, so it will, eventually, be a productive element for change. In fact, it's now possible for some sufferers to sign up for a Govt sponsored issue of Vit D supplements. As I recall, it's offered for a period of 4 months, but you had to sign up by mid Jan. Be interesting to see whether this moves forward.

    1. Not at only 10mcg of Vitamin D3 it won't. I could be cynical and say plan is built to fail. As David Davis puts it in the long video (about 11mins in) ...We are in the middle of a respiratory pandemic and NICE are fighting rickets.

    2. I'd forgotten the amount was so paltry, Linda. I didn't participate as there was 'advice' it might be contrary to one of my conditions. But you're right; box-ticking' and a recipe designed to 'prove' it doesn't really work. The current bunch of idiots in charge are desperate to replace the NHS with a medical insurance system along the lines of that in the US; a way for them and their cronies to make yet more profit, of course.
