How we worked it out

Magnesium

  • In the pack: 30 × 70 mg = 2.1 g
  • £35.99 ÷ 2.1 g × 100 mg = £1.71 per 100 mg magnesium
  • A week £1.71 × 7 = £12.00 · a month × 30 = £51.41 · a year × 365 = £625.54
  • Amount per serving: stated on the label.

Potassium

  • In the pack: 30 × 210 mg = 6.3 g
  • £35.99 ÷ 6.3 g × 200 mg = £1.14 per 200 mg potassium
  • A week £1.14 × 7 = £8.00 · a month × 30 = £34.28 · a year × 365 = £417.03
  • Amount per serving: stated on the label.
