Relationship Between Calcium Levels and Nail Health
- The chemical profile of the normal nail plate includes mineral composition, such as magnesium, calcium, iron, zinc, sodium, and copper 1.
- Studies have shown that fingernail and toenail calcium concentrations decrease with age in both men and women 2, 3.
- A significant positive correlation was found between fingernail calcium and lumbar bone mineral density (LBMD) 2, 3.
- Nail mineral content, including calcium, may be utilized as an indicator of bone mineral metabolism 2.
- The relationship between nail and bone health may exist in a measurable way, with nail properties linked to bone health 4.
- The measurement of fingernail calcium content may be useful as a predictor of osteoporosis 3.
- Calcium levels in nails may be affected by various factors, including age, bone mineral density, and nutritional status 1, 2, 5, 4, 3.
