How we worked it out

Iodine

  • Servings: 59 ÷ 0.2 per serving = 295
  • In the pack: 295 × 225 µg = 66.4 mg
  • £15.50 ÷ 66.4 mg × 150 µg = 3.5p per 150 µg iodine
  • A week 3.5p × 7 = 25p · a month × 30 = £1.05 · a year × 365 = £12.79
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 59 ÷ 0.2 per serving = 295
  • In the pack: 295 × 8 mg = 2.36 g
  • £15.50 ÷ 2.36 g × 100 mg = 65.7p per 100 mg magnesium
  • A week 65.7p × 7 = £4.60 · a month × 30 = £19.70 · a year × 365 = £239.72
  • Amount per serving: stated on the label.
