Calcium deficiency, which often goes undetected for several years, can cause low bone density and eventually osteoporosis.
Symptoms of calcium deficiency include aches, cramps, pins and needles in the hands and feet, spasms and twitching in the muscles.
Large intakes of magnesium and too much phosphorus – found in fizzy soft drinks – can upset your calcium balance.
