I am already taking 5000 IU D3 for winter, somewhat less in summer and times when I am outside. Last Dec. annual physical my D reading was 66 ngm/mL, midway in Kaiser Permanente’s Optimum Range of 50 to 80 ngm/mL. Will ask for the blood test at my Dec. annual physical.
I am also concerned about K1 and the inflammatory issue. I have allergies and take from 4 to 7 grams of Vitamin C a day and still my nose gets clogged as it is right now. Will pop a 1000 mg C as soon as I finish writing this. Does this mean I have inflammation?
What is this MK-7 and MK-4 you mention here?
If you go back to the link I gave you https://www.nutritionadvance.com/vitamin-k2-benefits/ , here are some key points:
There are many different forms of vitamin K2, but the two primary forms found in food are:
Menaquinone-4 (MK-4): animal foods such as dairy and meat contain MK-4.
Menaquinone-7 (MK-7): the best source of MK-7 is natto, a traditional Japanese fermented soy product. Other fermented soy dishes also have very high concentrations of MK-7.
On the other hand, vitamin K1 (phylloquinone) mainly occurs in plant foods, predominantly in dark green vegetables such as collard greens and spinach.

As previously mentioned, we can get vitamin K from K1 (mainly green vegetables) and K2 (animal foods and bacteria/fermented food sources).
With this in mind, one of the most significant benefits of vitamin K2 is that the MK-7 form (found in natto) has greater bioavailability than vitamin K1.
First of all, vitamin K1 has very poor bioavailability, and studies show that K1 absorption may be as low as 4% in foods like spinach.
Since vitamin K is fat-soluble, eating the spinach alongside a source of fat (butter) led to a threefold improvement in the absorption rate.
Although the precise absorption rate of vitamin K2 is not known, the consumption of menaquinone-7 significantly raises serum vitamin K levels.
The graph below (see link for graph) shows that vitamin K2 (MK-7) has a much greater absorption rate and half-life in the body, and keeps vitamin K levels high for several days
Additionally, the Rotterdam Study showed that menaquinone (K2) decreased the risk of arterial calcification and cardiovascular disease mortality. In contrast, phylloquinone (K1) had no such effect ).
Key Point: As evidenced by the absorption rate in numerous studies, vitamin K2 is significantly more bioavailable than K1.
We take 4,000 iu of D3 daily with the K2.
If you have inflammation take tumeric. We buy it in bulk online and make our own capsules. I have not taken Advil for arthritis in over two years.
