Calcium deficiency occurs when the body does not have enough calcium to support vital functions such as nerve signalling, muscle contraction, and bone strength. While traditionally associated with ageing and osteoporosis, calcium deficiency is increasingly being observed in younger adults. Modern lifestyles, poor dietary habits, limited sun exposure, and reliance on processed foods contribute to insufficient calcium intake. Early deficiency can silently affect the nervous system, muscles, and metabolism long before it begins to impact bone strength. Recognising calcium deficiency early is crucial to prevent long-term complications such as fractures, weakened bones, and impaired neurological function.
