Vitamin D levels in Swiss breast cancer survivors.

CONCLUSION: A remarkable fraction of the patients had serum 25(OH)D below (40%) or above (30%) optimal levels, and only around 30% of patients had optimal levels. Levels of 25(OH)D and 1,25(OH)2D increased on cholecalciferol supplementation, but the usual supplementation regimens were not adequate to bring 25(OH)D to the optimal range for a large proportion of patients.
