How we worked it out

Electrolytes

  • In the pack: 55 × 1 serving = 55 servings
  • £29.10 ÷ 55 servings × 1 serving = 52.9p per serving
  • A week 52.9p × 7 = £3.70 · a month × 30 = £15.87 · a year × 365 = £193.12
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • In the pack: 55 × 75 mg = 4.13 g
  • £29.10 ÷ 4.13 g × 500 mg = £3.53 per 500 mg calcium
  • A week £3.53 × 7 = £24.69 · a month × 30 = £105.82 · a year × 365 = £1287.45
  • Amount per serving: stated on the label.

Magnesium

  • In the pack: 55 × 120 mg = 6.6 g
  • £29.10 ÷ 6.6 g × 100 mg = 44.1p per 100 mg magnesium
  • A week 44.1p × 7 = £3.09 · a month × 30 = £13.23 · a year × 365 = £160.93
  • Amount per serving: stated on the label.

Potassium

  • In the pack: 55 × 1 g = 55 g
  • £29.10 ÷ 55 g × 200 mg = 10.6p per 200 mg potassium
  • A week 10.6p × 7 = 74p · a month × 30 = £3.17 · a year × 365 = £38.62
  • Amount per serving: stated on the label.
