Take a sufficient/normal/usual/typical amount of D3. Nothing excessive is required. K sometimes results in lower serum 25(OH)D, but it's not common.does magnesium lower calcium as well.
I don't get your first part. Maintaining serum 25 OHd has nothing to do with k2, but k2 results in lower 25ohd in some cases?
what needs to be done to ensure 25 OHD is maintained.
and if vitamin K reduces iodine/thyroid hormone uptake wouldnt it make hypothyroid people more hypo, and wouldnt it make everyone hypo unless they megadosed iodine alongside the k or something
Vitamin K's effect on thyroid may not be relevant, especially if taking only a few milligrams or less.
