How we worked it out

Electrolytes

  • In the pack: 60 × 1 serving = 60 servings
  • £47.45 ÷ 60 servings × 1 serving = 79.1p per serving
  • A week 79.1p × 7 = £5.54 · a month × 30 = £23.73 · a year × 365 = £288.65
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • In the pack: 60 × 60 mg = 3.6 g
  • £47.45 ÷ 3.6 g × 500 mg = £6.59 per 500 mg calcium
  • A week £6.59 × 7 = £46.13 · a month × 30 = £197.71 · a year × 365 = £2405.45
  • Amount per serving: stated on the label.

Magnesium

  • In the pack: 60 × 50 mg = 3 g
  • £47.45 ÷ 3 g × 100 mg = £1.58 per 100 mg magnesium
  • A week £1.58 × 7 = £11.07 · a month × 30 = £47.45 · a year × 365 = £577.31
  • Amount per serving: stated on the label.

Potassium
