You're right about that. Many people are Vitamin D deficient. But you don't solve that problem by taking a massive daily amount of Vitamin D.
You take a reasonable dose (a small increase in dose) and measure the new level.

My doc said I was “high” at 78ng/dL, but the research I’ve seen recommends maintaining 80ng/dL for optimal health. But obviously you need a test to know. D is not a cure-all, but there are certainly many facets of health that it affects, since it is actually a hormone and not a “vitamin”.
I believe depending on multiple factors and being fat soluble it is not rapidly excreted. It depends on your current levels, your state of health (how much your processes "need") etc - but it is multiple days.
Of course. Reading up and studying the topic is exactly my point.
"Taking 60,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity. This level is many times higher than the U.S. Recommended Dietary Allowance (RDA) for most adults of 600 IU of vitamin D a day.
Doses higher than the RDA are sometimes used to treat medical problems such as vitamin D deficiency, but these are given only under the care of a doctor for a specified time frame. Blood levels should be monitored while someone is taking high doses of vitamin D."
My VERY first words were....in case someone missed them, but yes seeing the responses, yours is a good reminder.
"Not giving advice other than start the conversation with your health care provider regarding having your blood level of Vitamin D checked"
That said, poke at your doctor. It's YOUR health.
In regard to K2, one doctor told me it was important only for blood-clotting in newborns. Seriously! As far as nutrition goes, doctors have on average received no more than 11 hours of education on that topic in medical school. 11 hours isn't much. I have had more than 11 hours in sensitivity training and how has that worked out?

I think I posted an article on the history and health connections from Nexus Magazine before. It’s a good read, and notes that if you’re taking an appropriate level of K2 along with D, toxicity is not an issue, as D liberates (or mobilizes, if you will) calcium and K2 directs it to the bones. Without K2, the calcium can end up in soft tissues and that’s what the “toxicity” is.
As in everything, moderation is key, along with plenty of personal research and consulting a trusted medical professional.

Knowing that d3 was often recommended to help resist the onset on respiratory ailments. Started taking 5000 iu every other day. Been doing it even before the pandemic. Colds and flu hate me.
I believe you’re talking about K1, that is the one that deals with blood clotting. K2 helps to direct calcium out of the blood and into the bones from what I’ve gathered from doctors and experts. But, do your own research.In regard to K2, one doctor told me it was important only for blood-clotting in newborns. Seriously!

I was talking about K2 to that doctor in the context of calcium. My point was that he didn't know about the calcium/K2 interaction. As far as clotting goes, K1, K2, and K3 play a role. K1 is for example in spinach while K2 is found in natto. Both foods, along with many others, affect blood clotting (INR test) in people on the most common blood thinners. K3 is a man-made substance.I believe you’re talking about K1, that is the one that deals with blood clotting.

My eyes glaze over when I hear someone use association studies to imply that a product can help prevent or cure virtually every disease known to man.
vitamin D can stay a long time, as all vitamins that are fat soluble
Your doctor is right. Almost no-one gets enough Vitamin D from sunlight alone. I even take a Vitamin D tab (1,000 IU) every day and I'm the original Vitamin supplement skeptic. For the record, I do believe in Vitamins, I just don't believe in trying to get them from a pill.
The other place where taking vitamins is recommended (strongly recommended actually) is taking Folic Acid along with iron during pregnancy. Folic Acid supplements almost entirely prevent neural tube defects in newborns.

That's not my understanding of his views on this at all. He's talked about vit d many times, he's quite conservative on the recommended dose. Even in this video he warns about the dangers of taking too much and suggests somewhere around 3000 to 5000 IIRC, while getting tested over a period of time.
Tablets are also less ideal than oil based vit d, as vit d is fat soluble.
He runs a clinic and does long term testing on many patients. He knows this stuff inside and out, and has a scientific/evidence based approach to health.
