Effects of High-Dose Vitamin D Supplementation on Bone Mineral Density

This chapter discusses a study that investigated the effects of different levels of vitamin D supplementation in adults aged 55 to 70 over a three-year period. The study found that high-dose supplementation did not provide significant benefits and may have negative impacts on bone mineral density. The chapter emphasizes the importance of considering the dosage and duration when supplementing with vitamin D and cautions against high-dose supplementation without proper clinical supervision.
