what is this saying in plain english? That we all need to take vitamin D supplements?

Basically yes. I didn't read the paper, but the abstract says that our current recommendations were designed to get us past a threshold of 50 (nmol/L, but the units aren't that important). But they claim that we should be aiming to get above 75, and it would be best if we could get above 100. So drink more fortified milk. Edit: oops, looks like I read it wrong. 50 nmol/L isn't the threshold the current RDA gets us to…

Milk costs more than a vitamin

This supports my lived experience. Found to be incredibly low in vitamin D, and diagnosed with autoimmune thyroiditis. Doctor said to supplement with 2000 IU being the max per day.

After seeing no improvement whatsoever in vitamin D levels, and after talking with others with the same issue, I self medicated to 10000 IU / day.

Lo and behold my vitamin D levels went back up and my auto-antibodies went back down.

This article recommends around 100 nmol/L. Most people are between 20-30, because they don't get enough Sun and do not take supplements. It gets really really bad when the number gets below 10 and it takes months to recover. Another Vitamin whose deficiency cause irreversible damage is B12. Folks, get both of these checked.

Because of impaired kidney function, I get my vitamin D levels monitored every month. Yes supplements can take 2-3 months to increase the levels. The sun actually works pretty good if you can stay outside 15 minutes in noon sun. But that's difficult in the winter months.

I happen to have a gene mutation that makes methylation of B12 inefficient. I never did well in chemistry or biology for that matter, but my limited understanding is that methylation is necessary for it to be useful. It turns out that you can buy methylated B12 called methylcobalamin. The more common form is cyanocobalamin, and is not very useful for people like myself. That is my understanding, if anyone here knows…

Thanks for this added information. I discovered the same thing, with another family member where Methylcobalamin worked wonders and Cyanocobalamin didn't.

One thing I would add is that Methylcobalamin needs to be injected to work best. If people do not have your gene mutation, they are better off taking Cyanocobalamin.

PS: Whenever someone in family has major health issue which no one can get handle on - they reach out to me. My lifelong dream has been to cure Cancer using AI. Just started working on that.

True, cyanocobalamin for people like you won't work.

Although consuming just methylcobalamin leaves out adenosylcobalamin.

Sufficient vitamin D is gained primarily from Sun exposure.. typically between 10am and 2pm, I have read that at certain latitudes and times of year the required window is considerably less but cannot find a reference. http://www.return2health.net/articles/does-vitamin-d-really-...

This is a very caucasian centric viewpoint.

The fact is that if you live in higher latitudes and have dark skin, you physically cannot absorb enough vitamin D from sunlight during the winter months. While it is physically possible during the summer, it is not practical to spend hours sunbathing.

I just want to say the b complexes are indeed super important, but recent studies indicate a potential link between overly high dosage and some types of cancers, particularly in men. So be wary of overdoing it with those 3000% dv supplements.

Another big challenge in winter months is that people are so covered with warm clothes, that even going out in Sun doesn't help much.
