How we worked it out

Electrolytes

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 1 serving = 30 servings
  • £43.45 ÷ 30 servings × 1 serving = £1.45 per serving
  • A week £1.45 × 7 = £10.14 · a month × 30 = £43.45 · a year × 365 = £528.64
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Magnesium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 60 mg = 1.8 g
  • £43.45 ÷ 1.8 g × 100 mg = £2.41 per 100 mg magnesium
  • A week £2.41 × 7 = £16.90 · a month × 30 = £72.42 · a year × 365 = £881.07
  • Amount per serving: stated on the label.

Potassium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 500 mg = 15 g
  • £43.45 ÷ 15 g × 200 mg = 57.9p per 200 mg potassium
  • A week 57.9p × 7 = £4.06 · a month × 30 = £17.38 · a year × 365 = £211.46
  • Amount per serving: stated on the label.
