How we worked it out

Potassium

  • Servings: 300 ÷ 10 per serving = 30
  • In the pack: 30 × 200 mg = 6 g
  • £19.45 ÷ 6 g × 200 mg = 64.8p per 200 mg potassium
  • A week 64.8p × 7 = £4.54 · a month × 30 = £19.45 · a year × 365 = £236.64
  • Amount per serving: stated on the label.

Electrolytes

  • Servings: 300 ÷ 10 per serving = 30
  • In the pack: 30 × 1 serving = 30 servings
  • £19.45 ÷ 30 servings × 1 serving = 64.8p per serving
  • A week 64.8p × 7 = £4.54 · a month × 30 = £19.45 · a year × 365 = £236.64
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Magnesium

  • Servings: 300 ÷ 10 per serving = 30
  • In the pack: 30 × 100 mg = 3 g
  • £19.45 ÷ 3 g × 100 mg = 64.8p per 100 mg magnesium
  • A week 64.8p × 7 = £4.54 · a month × 30 = £19.45 · a year × 365 = £236.64
