How we worked it out

Electrolytes

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 1 serving = 15 servings
  • £24.95 ÷ 15 servings × 1 serving = £1.66 per serving
  • A week £1.66 × 7 = £11.64 · a month × 30 = £49.90 · a year × 365 = £607.12
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Calcium

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 60 mg = 900 mg
  • £24.95 ÷ 900 mg × 500 mg = £13.86 per 500 mg calcium
  • A week £13.86 × 7 = £97.03 · a month × 30 = £415.83 · a year × 365 = £5059.31
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 50 mg = 750 mg
  • £24.95 ÷ 750 mg × 100 mg = £3.33 per 100 mg magnesium
  • A week £3.33 × 7 = £23.29 · a month × 30 = £99.80 · a year × 365 = £1214.23
  • Amount per serving: stated on the label.

Potassium

  • Servings: 15 ÷ 1 per serving = 15
  • In the pack: 15 × 400 mg = 6 g
  • £24.95 ÷ 6 g × 200 mg = 83.2p per 200 mg potassium
  • A week 83.2p × 7 = £5.82 · a month × 30 = £24.95 · a year × 365 = £303.56
  • Amount per serving: stated on the label.
