How we worked it out

Magnesium

  • Servings: 118 ÷ 4 per serving = 29.5
  • In the pack: 29.5 × 400 mg = 11.8 g
  • £13.49 ÷ 11.8 g × 100 mg = 11.4p per 100 mg magnesium
  • A week 11.4p × 7 = 80p · a month × 30 = £3.43 · a year × 365 = £41.73
  • Amount per serving: stated on the label.

Boron

  • Servings: 118 ÷ 4 per serving = 29.5
  • In the pack: 29.5 × 1.5 mg = 44.3 mg
  • £13.49 ÷ 44.3 mg × 3 mg = 91.5p per 3 mg boron
  • A week 91.5p × 7 = £6.40 · a month × 30 = £27.44 · a year × 365 = £333.82
  • Amount per serving: stated on the label.

Potassium

  • Servings: 118 ÷ 4 per serving = 29.5
  • In the pack: 29.5 × 5 mg = 147.5 mg
  • £13.49 ÷ 147.5 mg × 200 mg = £18.29 per 200 mg potassium
  • A week £18.29 × 7 = £128.04 · a month × 30 = £548.75 · a year × 365 = £6676.41
