Calcium deficiency can have significant effects on health, particularly on bone density and strength. Insufficient calcium intake may lead to osteoporosis, increasing the risk of fractures and breaks in later life. Additionally, calcium plays a vital role in muscle function, blood clotting, and nerve transmission. A deficiency can result in symptoms like numbness, muscle cramps, and in severe cases, heart rhythm disturbances. Long-term calcium deficiency can also contribute to dental health issues. Therefore, maintaining adequate calcium levels is essential for overall physical stability and function.
