How we worked it out

Electrolytes

  • Servings: 26 ÷ 1 per serving = 26
  • In the pack: 26 × 1 serving = 26 servings
  • £31.00 ÷ 26 servings × 1 serving = £1.19 per serving
  • A week £1.19 × 7 = £8.35 · a month × 30 = £35.77 · a year × 365 = £435.19
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • Servings: 26 ÷ 1 per serving = 26
  • In the pack: 26 × 120 mg = 3.12 g
  • £31.00 ÷ 3.12 g × 500 mg = £4.97 per 500 mg calcium
  • A week £4.97 × 7 = £34.78 · a month × 30 = £149.04 · a year × 365 = £1813.30
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 26 ÷ 1 per serving = 26
  • In the pack: 26 × 100 mg = 2.6 g
  • £31.00 ÷ 2.6 g × 100 mg = £1.19 per 100 mg magnesium
  • A week £1.19 × 7 = £8.35 · a month × 30 = £35.77 · a year × 365 = £435.19
  • Amount per serving: stated on the label.
