How we worked it out

Electrolytes

  • In the pack: 45 × 1 serving = 45 servings
  • £34.49 ÷ 45 servings × 1 serving = 76.6p per serving
  • A week 76.6p × 7 = £5.37 · a month × 30 = £22.99 · a year × 365 = £279.75
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • In the pack: 45 × 50 mg = 2.25 g
  • £34.49 ÷ 2.25 g × 500 mg = £7.66 per 500 mg calcium
  • A week £7.66 × 7 = £53.65 · a month × 30 = £229.93 · a year × 365 = £2797.52
  • Amount per serving: stated on the label.

Magnesium

  • In the pack: 45 × 25 mg = 1.13 g
  • £34.49 ÷ 1.13 g × 100 mg = £3.07 per 100 mg magnesium
  • A week £3.07 × 7 = £21.46 · a month × 30 = £91.97 · a year × 365 = £1119.01
  • Amount per serving: stated on the label.
