How we worked it out

Electrolytes

  • In the pack: 15 × 1 serving = 15 servings
  • £35.49 ÷ 15 servings × 1 serving = £2.37 per serving
  • A week £2.37 × 7 = £16.56 · a month × 30 = £70.98 · a year × 365 = £863.59
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Magnesium

  • In the pack: 15 × 100 mg = 1.5 g
  • £35.49 ÷ 1.5 g × 100 mg = £2.37 per 100 mg magnesium
  • A week £2.37 × 7 = £16.56 · a month × 30 = £70.98 · a year × 365 = £863.59
  • Amount per serving: stated on the label.

Potassium

  • In the pack: 15 × 150 mg = 2.25 g
  • £35.49 ÷ 2.25 g × 200 mg = £3.15 per 200 mg potassium
  • A week £3.15 × 7 = £22.08 · a month × 30 = £94.64 · a year × 365 = £1151.45
  • Amount per serving: stated on the label.

Zinc

  • In the pack: 15 × 3 mg = 45 mg
  • £35.49 ÷ 45 mg × 15 mg = £11.83 per 15 mg zinc
  • A week £11.83 × 7 = £82.81 · a month × 30 = £354.90 · a year × 365 = £4317.95
