Vitamin D, Essential Minerals, and Toxic Elements: Exploring Interactions between Nutrients and Toxicants in Clinical Medicine

Table 2

Vitamin D levels achieved in 2 studies done at northern latitudes.

	Number	Percentage
() Higher latitude statistics for high levels of 25(OH)D3, = 1430 [2]
Number of patients with >150 nmol/L of 25(OH)D3	15	1%
Number of patients with >100 nmol/L of 25(OH)D3	315	22%
Number of patients with ideal levels 100–150 nmol/L	300	21%
() Nursing home study using 2000 IU daily of vitamin for >5 months, = 68 [63]
Number of patients with >150 nmol/L of 25(OH)D3	6	9%
Number of patients with >100 nmol/L of 25(OH)D3	54	78%
Number of patients with ideal levels 100–150 nmol/L	48	71%

All levels achieved in these patients were well below 375 nmol/L where side effects have been reported.
