Vitamin D also TREATS

TREATED successfully = "Controlled by" or "Helped by" or "Suppresses"
Hesitant to say that vitamin D can cure a disease. It is very difficult to reverse damage.
Observations:
Diseases TREATED by vitamin D appear to be a subset of those which vitamin D can PREVENT.
PREVENTION appears to need > 30 ng and TREATMENT appears to need 40-60 ng of vitamin D
Appear to need about 4X as much IU of vitamin D to TREAT as to PREVENT a disease
Often need one or more of the vitamin D cofactors to TREAT a disease, especially Calcium, Magnesium, Vitamin K2
- Perhaps because the cofactors increase the bio-availability of vitamin D
