How we worked it out

Electrolytes

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 1 serving = 15 servings
  • £20.00 ÷ 15 servings × 1 serving = £1.33 per serving
  • A week £1.33 × 7 = £9.33 · a month × 30 = £40.00 · a year × 365 = £486.67
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 50 mg = 750 mg
  • £20.00 ÷ 750 mg × 500 mg = £13.33 per 500 mg calcium
  • A week £13.33 × 7 = £93.33 · a month × 30 = £400.00 · a year × 365 = £4866.67
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 100 mg = 1.5 g
  • £20.00 ÷ 1.5 g × 100 mg = £1.33 per 100 mg magnesium
  • A week £1.33 × 7 = £9.33 · a month × 30 = £40.00 · a year × 365 = £486.67
  • Amount per serving: stated on the label.

Potassium

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 250 mg = 3.75 g
  • £20.00 ÷ 3.75 g × 200 mg = £1.07 per 200 mg potassium
  • A week £1.07 × 7 = £7.47 · a month × 30 = £32.00 · a year × 365 = £389.33
  • Amount per serving: stated on the label.
