How we worked it out

Calcium

  • Servings: 120 ÷ 4 per serving = 30
  • In the pack: 30 × 1 g = 30 g
  • £38.66 ÷ 30 g × 500 mg = 64.4p per 500 mg calcium
  • A week 64.4p × 7 = £4.51 · a month × 30 = £19.33 · a year × 365 = £235.18
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 120 ÷ 4 per serving = 30
  • In the pack: 30 × 100 mg = 3 g
  • £38.66 ÷ 3 g × 100 mg = £1.29 per 100 mg magnesium
  • A week £1.29 × 7 = £9.02 · a month × 30 = £38.66 · a year × 365 = £470.36
  • Amount per serving: stated on the label.
