Vitamin D3 Supplementation

Vitamin D3 plays a crucial role in skeletal health, immune function, and metabolic regulation. Supplementation reduces the risk of fractures, especially when combined with calcium, and is associated with a significant reduction in all-cause mortality. Meta-analyses show that long-term Vitamin D supplementation reduces all-cause mortality by 6% and cancer mortality by 13%. These benefits are particularly notable in older adults, where sufficient Vitamin D levels are linked to better immune health, lower inflammation, and reduced risk of cardiovascular disease.
