Official title
The Effects of Vitamin D and Calcium Supplementation at Tolerable Upper Limit Doses on Calcium Metabolism in Postmenopausal White Women.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Recently two distinguished committees, Institute of Medicine (IOM) and The Endocrine Society have proposed different intake guidelines for Calcium and Vitamin D. We wish to compare the effects of both of them on calcium metabolism and bone turnover. We propose a one year randomized double blinded study for the same.
