True but it isn’t that bad.
I’ll keep an eye on it.
I get the sun when I’m in the car anyway.
There was recently some stuff about how much UV was blocked out by modern glass.
Tobe honest, if it is consistent, then a trundle off to the Doc, or nurse, is worthwhile. I'd agree it would be good to have your VitD levels checked, as a decent proportion of folks in the UK are running low on it. The NHS threshold for diagnosing a defficiency is very low, in my view. I prefer my own levels to skirt around the 100 mark.
I was found to be defficient last year, following my thyroid beginning to struggle, so had a loading course of D3 +K2, then continued to supplement at a lower dose, through the winter. I paused my supplement whilst spending 2 months in SE Asia. Even though I was outside, a lot, in the sun, my levels didn't soar in quite the expected way. My blood test was the same before and after all that natural sunshine.
Not so long ago, someone pointed out to me a paper suggesting a goodly proportion of VitD created from sunshine on the skin is actually washed away.
