"IMPORTANT: If You Take Vitamin D, You Need K2
This is a really crucial point: If you opt for oral vitamin D, you need to also consume in your food or take supplemental vitamin K2.
Whoa there partner!
You also should brush your teeth, say your prayers and kiss your mum good night.
All my alarms went off when I saw this unsupported assertion: "We don't see symptoms of vitamin D toxicity very often. But when we do, those symptoms are inappropriate calcification. That's the symptom of vitamin D toxicity. And it is actually a lack of vitamin K2 that can cause that..."
That's complete nonsense. We know very well how high doses of Vitamin D cause hypercalcemia and it has everything to do with the effects on PTH, and increased calcium absorption and nothing to do with K2.
I've been banging around high dose Vitamin D quite intensively for the past 12 years as a way to control calcium in cats suffering renal failure. I don't recall ever seeing anything that said K2 was critical to the absorption or conversion of Vitamin D and certainly nothing to suggest that it plays a role in Vitamin D induced hypercalcemia.
I just did a quick PubMed search and while there are 217 articles mentioning both K2 and Vitamin D, none appear to be in the context that you laid out here. K2 is required for bone health and that involvement is tied to the interactions between K2 and calcium. Vitamin D only gets mentioned in this context because it is usually deficient, not because it has any specific link to K2.
So I repeat. Good health probably means that we shouldn't be deficient in any essential mineral or vitamin, but that is not the same as saying that any particular mineral or vitamin is vitally linked to another.
The body is a system so at some level, everything is linked to everything else, but again, that is not to say that there is a direct link between K2 and Vitamin D.
Just my opinion. I'm completely open to any scientific evidence that there is a direct link requiring supplementation, but until then, I think just eating well and getting enough solar exposure are probably all that is necessary, assuming of course, no specific deficiencies.
I know that natto is a good source of K2 so my guess is that Vegemite is too so you are probably completely covered.

As bright as bright can be.
We all enjoy our Vegemite
For breakfast, lunch, and tea.

Every single week,
Because we love our Vegemite
We all adore our Vegemite
