I suspect that blood vitamin D is mainly a marker for how much outdoor exercise people are getting, and that it is the exercise rather than the D which is causal.
My life changed after I got tested for vit D and started talking supplements. I was severely deficient. I am now sufficient and everything changed for me.
Earlier quoted context omitted.
But then why do we see improvements in people that get vitamin D + K2 supplements and not exercise?
As the article mentions, we pretty much don't see improvements with supplementation.
> the balance of evidence tips pretty clearly in the direction that people with low-ish levels would be wise to supplement

This is a refreshingly balanced and honest analysis of Vitamin D studies. The strongest evidence for Vitamin D is in people who are severely deficient. Bumping up to a normal range can provide some improvements. The health influencers started noticing that the Vitamin D studies coming out weren't matching their original hype for Vitamin D, so many pivoted to trying to make claims that most people are severely deficie…

On a slight tangent, if people are unaware, you can pay for and get just about any lab test without a prescription in the United States.
The very premise that loading up your body with "excess" vitamins beyond what you need is already pretty fraught. Building a house without enough lumber can lead to long term deficiency - but loading up a construction site with more materials than are needed shouldn't automatically be assumed to be good.
The reality is that the modern diet has already solved so many common nutrient deficiency diseases (pellagra and goiters were a shockingly common diseases 100 years ago) that maxing out on vitamin intake has become more of something like a speculative hobby than anything else.
Has anyone done a RCT of D3+K2? K2 seems to be important in the absorption of D3. Another aspect that bothers me with these studies is that we’re simply supplementing the vitamin D, seemingly without measuring the change in blood levels. I took 2000IU (+K2) a day for many years in between testing my blood levels and still had <30ng/ml and had to go up to 5000IU/day. I’d like to see some further study.
Switched to 5000iu +K2 in MCT oil, -- 8 months later I'm at 64ng/ml.

For example, I've been supplementing with nicotinamide riboside for a few years now. I stop occasionally and when I do stiff and sore hands and knees return and I get more headaches.
I'd love to know if I'm deluding myself (placebo effect?) or there's good science that backs up my experience.
I never heard that in Germany. I only heard that if you use certain medications like cortisone that vitamin d could be problematic. Most doctors will give vitamin d supplements when prescribing cortisone, at least in Germany.
