Heading away for a very early night, so tired it's ridiculous.

Before I took ill 99% of my life was spent outside so I didn't need them. Hoping things will let me return to this in the New Year. I feel tired and sluggish the now but doc says it's the op.

Wife and I take one daily (NHS recommended dose) along with our medications

Marge keeps reminding me to take a Vitamin D pill every day.  If I remember, I put one in along with all my other pills.  I suppose she knows what is best, so I am happy to continue.

Sit out in the sun when there is any .

I saw a YouTube video when a doctor (maybe of course it was YouTube) was saying that the accepted supplementary dose had been miscalculated some years back. This had been pointed out by another study but never corrected. The video was called the big vitamin D mistake and I found a report with the same name...

https://pmc.ncbi.nlm.nih.gov/articles/PMC5541280/

That being a US government site makes this seem more official than YouTube. I haven't trawled the whole thing and as the error was {predictably} in statistics. Now to me statistics is all voodoo so I'd have no idea what the fuss is about but her are some excerpts

First paragraph probably for practitioners of the dark arts
Since 10 000 IU/d is needed to achieve 100 nmol/L [9], except for individuals with vitamin D hypersensitivity, and since there is no evidence of adverse effects associated with serum 25(OH)D levels <140 nmol/L, leaving a considerable margin of safety for efforts to raise the population-wide concentration to around 100 nmol/L, the doses we propose could be used to reach the level of 75 nmol/L or preferably 100 nmol/L. Of course, these recommended doses can be individualized based on dietary and sun exposure habits and the latitude of the country, and they can also be adjusted according to body mass index, age, and skin color, with obese, elderly, and dark-skinned people needing higher doses.

Closer to understandable
More importantly, according to the Endocrine Society's clinical practice guidelines, doses up to 1000 IU/d for infants up to 6 months, 1500 IU/d for infants from 6 months to 1 year, 2500 IU/d for children aged 1-3 years, 3000 IU/d for children aged 4-8 years, and 4000 IU/d for everyone over 8 years can be given safely without medical supervision just to prevent vitamin D deficiency, while higher doses may be needed to correct hypovitaminosis D.

And

CONCLUSION
Unfortunately, medicine took a very long time to realize that vitamin D is not simply a vitamin that prevents rickets. For that purpose, 400-600 IU/d may be enough. However, we know today that vitamin D is a powerful nuclear receptor-activating hormone of critical importance, especially to the immune system. With the available data mentioned above, the proposed doses would probably suffice to maintain vitamin D levels around or over 75-100 nmol/L, with practically zero risk of toxicity. Undeniably, further studies are needed to clarify the optimal supplementation of vitamin D, although it is uncertain whether a universal recommended dietary allowance is feasible. Meanwhile, actions are urgently needed to protect the global population from the threats posed by vitamin D deficiency.

My views.
I usually reckon we have survived a couple of million years without vitamin pills. OTOH there are a lot of things that impact our health that medicines of one sort or another overcome.

The clincher for me is that Amazon is awash with vitamin D pills offering 4,000 IU which is apparently 100ug and several multiples of what a bottle of multivitamins I have says is the recommended daily dose. That means this must be well known.

The final clincher is that bottles of 400 cost less than a tenner so I ordered some.

I did not.  Perhaps next time.

Yes, the Christmas scammers are out, Scrumps.
I just had an email this morning pretending to be Costa Coffee,   saying I had won a tumbler??
Then they wanted me to click on their link to qualify.

Firstly, I don't think I have ever been in a Costa Coffee shop,  and secondly,  I checked the email address and it came back as  'BAD.'
