Hair Calcium Paradox: A Report of Two Cases of Controlled Intermittent Dietary Calcium, Magnesium, and Vitamin D Supplementation
January 2007
TLDR Increased calcium in hair may signal early bone health issues in menopausal women.
The document reported on two cases involving controlled intermittent dietary supplementation of calcium, magnesium, and vitamin D in menopausal women, highlighting the "calcium paradox," where increased calcium in hair indicated decreased calcium in bones. This phenomenon was identified as an early sign of metabolic changes leading to osteopenia or osteoporosis, occurring even before differences could be detected by DEXA imaging. The study suggested that monitoring hair for osteotrophic elements could serve as an early indicator of bone health issues in menopausal women.
