Summary
This study examined the effects of weekly 35,000 IU vitamin D supplementation for 4 weeks on bone turnover markers (BTMs). There was improvement in the levels of parathyroid hormone (PTH), osteocalcin, and carboxy-terminal telopeptides of crosslinks of type 1 collagen (βCTX) which paralleled the increase in vitamin D levels.
Purpose
The effects of vitamin D supplementation on bone turnover markers (BTMs) have been inconsistent. This study examined the effects of weekly 35,000 IU vitamin D supplementation for 1 month on BTMs.
Methods
Sixty-eight vitamin D deficient adolescent females were given 35,000 IU of vitamin D3 for 4 weeks. Pre and post intervention blood samples were taken for 25(OH) D, PTH, osteocalcin and βCTX.
Results
There was a significant increase in serum 25 (OH) D in the post intervention period which was accompanied by a significant decrease in PTH, osteocalcin and βCTX (P < 0.001).
Conclusions
We concluded that weekly 35,000 IU vitamin D supplementation for 4 weeks results in significant improvement of BTMs.
