I previously posted questions to the community about low Vitamin D and received many suggestions which is appreciated. My Vit D is still low in spite of continued supplementation.
One researcher discussed the issue of an inversion which is the most logical in my situation. The idea is that serum levels of Vitamin D register low (which is the inactive form of Vitamin D) while the active form is normal. The article linked below discusses this very issue, it is found in auto-immune diseases, and I am not sure if it a problem with VDR (Vitamin D receptor),
Another researcher has suggested that Nattokinase and Metformin are able to correct this since they target the VDR.
