  • In the pack: 90 × 165 mg = 14.9 g
  • £24.48 ÷ 14.9 g × 500 mg = 82.4p per 500 mg calcium
  • A week 82.4p × 7 = £5.77 · a month × 30 = £24.73 · a year × 365 = £300.85
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 82.5 mg = 7.43 g
  • £24.48 ÷ 7.43 g × 100 mg = 33p per 100 mg magnesium
  • A week 33p × 7 = £2.31 · a month × 30 = £9.89 · a year × 365 = £120.34
