  • In the pack: 60 × 1.04 g = 62.1 g
  • £46.99 ÷ 62.1 g × 100 mg = 7.57p per 100 mg magnesium
  • A week 7.57p × 7 = 53p · a month × 30 = £2.27 · a year × 365 = £27.62
  • Amount per serving: stated on the label.

Potassium

  • Servings: 150 ÷ 2.5 per serving = 60
  • In the pack: 60 × 99 mg = 5.94 g
  • £46.99 ÷ 5.94 g × 200 mg = £1.58 per 200 mg potassium
  • A week £1.58 × 7 = £11.08 · a month × 30 = £47.46 · a year × 365 = £577.49
