How we worked it out

Magnesium

  • Servings: 237 ÷ 4.9 per serving = 48.4
  • In the pack: 48.4 × 190 mg = 9.19 g
  • £19.99 ÷ 9.19 g × 100 mg = 21.8p per 100 mg magnesium
  • A week 21.8p × 7 = £1.52 · a month × 30 = £6.53 · a year × 365 = £79.40
  • Amount per serving: stated on the label.

Electrolytes

  • Servings: 237 ÷ 4.9 per serving = 48.4
  • In the pack: 48.4 × 1 serving = 48.4 servings
  • £19.99 ÷ 48.4 servings × 1 serving = 41.3p per serving
  • A week 41.3p × 7 = £2.89 · a month × 30 = £12.40 · a year × 365 = £150.85
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Potassium

  • Servings: 237 ÷ 4.9 per serving = 48.4
  • In the pack: 48.4 × 150 mg = 7.26 g
  • £19.99 ÷ 7.26 g × 200 mg = 55.1p per 200 mg potassium
  • A week 55.1p × 7 = £3.86 · a month × 30 = £16.53 · a year × 365 = £201.14
