Vitamin D plays a critical role in skeletal homeostasis. Vitamin D supplementation is used worldwide to maintain optimal bone health. The most applicable level of supplementation is still questionable.
Experimental study was conducted supplying mice with diets with different doses of Vitamin D and dietary supplementation. It was concluded that Vitamin D supplementation leads to tougher bone than supplied with dietary vitamin D.
Observational study was also conducted and all diets were tolerated without adverse effects on body weight.
