How we worked it out

Electrolytes

  • Servings: 12 ÷ 1 per serving = 12
  • In the pack: 12 × 1 serving = 12 servings
  • £29.99 ÷ 12 servings × 1 serving = £2.50 per serving
  • A week £2.50 × 7 = £17.49 · a month × 30 = £74.97 · a year × 365 = £912.20
  • Amount per serving: priced per serving — compare what each serving contains before choosing.

Magnesium

  • Servings: 12 ÷ 1 per serving = 12
  • In the pack: 12 × 60 mg = 720 mg
  • £29.99 ÷ 720 mg × 100 mg = £4.17 per 100 mg magnesium
  • A week £4.17 × 7 = £29.16 · a month × 30 = £124.96 · a year × 365 = £1520.33
  • Amount per serving: stated on the label.

Potassium

  • Servings: 12 ÷ 1 per serving = 12
  • In the pack: 12 × 200 mg = 2.4 g
  • £29.99 ÷ 2.4 g × 200 mg = £2.50 per 200 mg potassium
  • A week £2.50 × 7 = £17.49 · a month × 30 = £74.97 · a year × 365 = £912.20
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 12 ÷ 1 per serving = 12
  • In the pack: 12 × 100 mg = 1.2 g
  • £29.99 ÷ 1.2 g × 1 g = £24.99 per 1 g
  • A week £24.99 × 7 = £174.94 · a month × 30 = £749.75 · a year × 365 = £9121.96
  • Amount per serving: stated on the label.
