How we worked it out

Electrolytes

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 1 serving = 30 servings
  • £24.50 ÷ 30 servings × 1 serving = 81.7p per serving
  • A week 81.7p × 7 = £5.72 · a month × 30 = £24.50 · a year × 365 = £298.08
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 50 mg = 1.5 g
  • £24.50 ÷ 1.5 g × 500 mg = £8.17 per 500 mg calcium
  • A week £8.17 × 7 = £57.17 · a month × 30 = £245.00 · a year × 365 = £2980.83
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 100 mg = 3 g
  • £24.50 ÷ 3 g × 100 mg = 81.7p per 100 mg magnesium
  • A week 81.7p × 7 = £5.72 · a month × 30 = £24.50 · a year × 365 = £298.08
  • Amount per serving: stated on the label.

Potassium

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 250 mg = 7.5 g
  • £24.50 ÷ 7.5 g × 200 mg = 65.3p per 200 mg potassium
  • A week 65.3p × 7 = £4.57 · a month × 30 = £19.60 · a year × 365 = £238.47
