How we worked it out

Calcium

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 400 mg = 72 g
  • £13.99 ÷ 72 g × 500 mg = 9.72p per 500 mg calcium
  • A week 9.72p × 7 = 68p · a month × 30 = £2.91 · a year × 365 = £35.46
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 200 mg = 36 g
  • £13.99 ÷ 36 g × 100 mg = 3.89p per 100 mg magnesium
  • A week 3.89p × 7 = 27p · a month × 30 = £1.17 · a year × 365 = £14.18
  • Amount per serving: stated on the label.
