How we worked it out

Calcium

  • Servings: 120 ÷ 1 per serving = 120
  • In the pack: 120 × 400 mg = 48 g
  • £12.29 ÷ 48 g × 500 mg = 12.8p per 500 mg calcium
  • A week 12.8p × 7 = 90p · a month × 30 = £3.84 · a year × 365 = £46.73
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 120 ÷ 1 per serving = 120
  • In the pack: 120 × 200 mg = 24 g
  • £12.29 ÷ 24 g × 100 mg = 5.12p per 100 mg magnesium
  • A week 5.12p × 7 = 36p · a month × 30 = £1.54 · a year × 365 = £18.69
  • Amount per serving: stated on the label.
