Calcium deficiency risks are high globally (51% in 2011), with animal products being the major source of dietary calcium in many regions.
Calcium deficiency is a major global health issue, affecting over half the world's population. Ensure adequate intake through dietary sources, particularly if you live in or consume foods from regions with high deficiency risks.
